50 high payout online slots and their RTP listed

We have decided against listing these slots by their RTP rate and instead, have gone for alphabetical order. This way, you can quickly check our list to see if a game you like qualifies as one of the top fifty best paying slots. As we have said, we have a separate bigger page listed by RTP. So, let’s begin…

1429 Uncharted Seas (Thunderkick, 98.63% RTP)Based on early myths of the seas, this Thunderkick developed slot features all manner of sea monsters, from krakens to mermaids, sea serpents and beyond. Simple and with ancient map-like graphics, the slot offers 25 fixed lines over its 5 reels and can be played for as little as 0.10 per spin. Of course, if you’re feeling adventurous, up to 100.00 a game can be staked. The RTP rate in this game trumps virtually anything else from Thunderkick at 98.63%, and the slot carries a non-progressive prize worth a petite 50x your total stake because of its high RTP rate.
Players of this game can expect to find a stacked wild which appears on the three central reels, and a compass scatter which can trigger a free games bonus. The free spins can be re-triggered by landing more scatters on the reels of the game while the bonus is being played. There is nothing particularly impressive about the free spin bonus, but with up to 50 free spins up for grabs, and such a high RTP rate, wins are a regular occurrence with this charming but straightforward slot.

After Night Falls (BetSoft Gaming, 97.27% RTP)
After Night Falls is one of those wonderful 3D slot machines that BetSoft Gaming is so famed for. There is something very Inspector Clouseau about this game, which offers up a non-progressive haul of 1,550,000 credits if you strike it lucky. After Night Falls allows all 30 of its paylines to be adjusted by players, and you can expect to be able to alter the number of coins you stake per line and coin values, too, with bets ranging from a floor of 0.01 per line per spin, up to 150.00 per spin.
There is a free spin mode in this game, which is triggered via case file scatters. The bonus promises up to 25 free spins, with multipliers ranging from 2x up to 10x. Moving wilds are triggered when a magnifying glass appears on the reels, and if they keep appearing on the reels, re-spins are granted. A 5 Rooms Click Me bonus is yours if you can land 3 or more criminal symbols on the reels, and this feature dishes out instant wins. Meanwhile, when a reel contains stacked symbols, those symbols can collapse offer players the potential to win several times on a single spin. Like most BetSoft slots, a Double Up gamble feature has also been included in this game, which has an above average RTP rate of 97.27%.

Alchemist’s Lab (Playtech, 97.30% RTP)
The first three-reel slot make it onto our list is Playtech’s Alchemist’s Lab. Similar in theme to Playtech’s Alchemist’s Spell, this classic slot may only contain 3 reels and a single pay-line, but it is capable of dishing out wins worth around 10,000x your total bet, which is not to be sniffed at. The classic slot also has an above average RTP figure of 97.3%. The one downside to the game is that it does prove costly to play, with wagers stretching from 1.00 up to 30.00 a game. Players should know well enough what to expect with this game in terms of theme, given its rather self-explanatory title.
Often, classic slots such as this do not come with a wealth of special features thrown into the mix. Alchemist’s Lab does, though. A bonus round is effectively triggered when players land 3 of the spell book symbols on the reels. Once the bonus has been triggered, players will be invited to select three potions from several which appear on the screen. These are then added together to give you a total instant win bonus prize haul. Players who like this game may also wish to try Alchemist’s Spell. Although they aren’t directly related, the two slots contain the same theme, and more importantly, the 5-reel, spell slot has the same RTP rate as this 3-reel title.

At the Copa (BetSoft Gaming, 97.42% RTP)
Another one of BetSoft Gaming’s truly mesmerizing 3D slot machines, At the Copa, is a Copacabana-themed video slot, and one which delivers all manner of tropical and musical symbols to players on its 5 reels and 30 lines. Like other BetSoft slots, players have total control over how much they stake, what those coins are worth, how many coins they wager, and the number of lines they play with. This is handy in a game which has an RTP rate of 97.42% and a non-progressive jackpot prize which is capped at 2,500x your total bet. However, the slot also dishes out progressive prizes. Suave, Mediano and Caliente jackpots can be yours depending on how many chillies you land, where you land them, and whether you are playing with the maximum stake or not.
At the Copa is not short of special symbols and features, either. Wild symbols can replace all but other bonus icons, and if they land in the middle of the third reel, they can expand to cover the entire reel, while delivering a re-spin. The more times you win here, the more re-spins you will get, with each re-spin profiting from an increasing multiplier. The slot also delivers a standard free spin bonus (triggered by stiletto shoes on the first, third and fifth reels) and players can select a dancer to act as a secondary wild in this bonus. The slot offers a click and win-based dancing bonus.

Atari Asteroids (Pariplay, 97% RTP)
Pariplay’s only entry on our top 50 list of the best paying online slots is Atari Asteroids. It features a rather unique 3-4-5-4-3-reel structure and comes with a “720 ways to win” pay-line structure. Wagers are a bit costlier than some players would like at a minimum of 0.50 per spin and a maximum of 25.00 a game, though. The non-progressive jackpot of 600x your total bet makes for exciting game play, though, in this slot, which is themed on old-school space gaming. The wild is unmissable, appearing as a big block of text, and it can expand to fill entire reels at times, triggering re-spins as it does so.
Wilds aren’t the only goodies you can come across in this game. Players will also note that Atari Asteroids also delivers free spins to its players. These are triggered via scatter icons and can see players win up to 30 free spins in all. Those spins are played on a second set of reels in this game, which carries an RTP rate of 97%; vastly more than any other slot from this developer.

Barber Shop/Barber Shop Uncut (Thunderkick, 97% RTP)
Barber Shop has recently had a bit of a redesign and been relaunched as Barber Shop Uncut. Whichever version of this Thunderkick slot you happen to play, though, will still offer you an RTP rate of 97%, which is more than in many other slots. Graphically, this barber-themed slot is a hoot with simple, paper-style imagery, some of which is quite creative. The usual 5-reel, 25-line format can be found in this game, which costs between 0.10 and 100.00 a spin, and can dish out wins worth a lowly 40x your total bet. That might sound petite, but with such a high RTP rate, we’re prepared to overlook that.
Barber Shop and revamped Uncut version both offer up a re-spin bonus whenever players manage to land a winning combo on the reels. Re-spins will continue to come your way until no new winning combinations are acquired on the reels. Players need 5 bonus symbols to appear on the reels to trigger this slot’s free spin feature, but when they do, they can walk away with a handful of spins, multipliers worth up to 5x, and the Inwinity Feature. This Thunderkick developed feature guarantees players a win on the final spin, so the reels will keep spinning until that occurs.

Beverley Hills 90210 (iSoftBet, 97.09% RTP)
No prizes are awarded for guessing the theme and inspiration behind this slot machine. The first iSoftBet to make our list, Beverley Hills 90210 is a branded slot and one which has an impressive RTP of just over 97%. All your favourite 90s characters are present on the 5 reels and 243 pay-lines of this game, which costs between 0.50 and 25.00 a spin. How much can you win, then? Well, the non-progressive jackpot is capped at a woeful 10x your total bet but considering there are 243 lines and plenty of chances to win with this decent RTP rate, most players won’t mind that one bit.
This slot is also jam-packed with features. Players can expect to be able to find modifiers which can switch the direction of the paylines (or even trigger wins in both directions), a free spin bonus which can offer up to 25 free games, and two distinct types of bonuses, one for the boys and one for the girls. The boys’ free spin bonus offers up to 3 wild reels, while the girls’ free spin bonus promises between 1 and 5 wilds per spin. The choice, though, is entirely down to you.

Big Bad Wolf (Quickspin, 97.35% RTP)
Quickspin’s Big Bad Wolf is one of the most popular slot machine games on the net, and not just with fans who like nursery rhyme-themed titles. It is also popular becomes of generous 1,000-coin non-progressive jackpot, 97.35% RTP rate, and dirt-cheap stakes, which range from 0.25 up to 250.00 a game. If none of that does it for you, and the nifty graphics don’t strike a chord, either, you can always indulge in some of the slot’s many special features. Where do we begin with those? There are so many to choose from.
For starters, there is a cascading reel feature in this slot. It occurs whenever a win is landed, with winning symbols removed and replaced by new ones, potentially allowing players to net multiple wins on a single spin. The slot also contains a counter system whereby when pig counters are filled, they will become additional wilds. Lastly, there is an impressive free spin bonus. This feature can not only dish out free games but see the wolf try to blow down houses by landing moon symbols on the reels. Each time the wolf blows down a house, players will pocket 2 extra spins and a 2x multiplier on their winnings.

Big Red (Aristocrat, 97.04% RTP)
Aristocrat’s Big Red is not the most commonly offered slot game on the net, but if you do come across it, you are certainly going to want to give it a run for its money. This game is themed on typical wildlife, with an emphasis on Australian animals. Set in the outback (although the animals on the reels look out of place here) this game costs between 0.10 and 50.00 a game, features a basic 5-reel, 5-line format, and can dish out wins worth 1,250x your total bet. Its RTP is well above what we would expect from Aristocrat, at 97%.
Don’t expect too much in the way of special features here. Big Red can deliver a free spin bonus, but only when a wild (kangaroo) appears in a winning combo. This unusual way of triggering the feature offers 5 spins, but you only get a handful of spins on individual lines, which is just bizarre. The slot also features a gamble feature, so players can gamble their winnings if they wish. Bizarre and quirky it may be (and that could be why it is not commonly found), but few players are going to grumble at an RTP rate of above 97% now, are they?

Blood Suckers (Net Entertainment, 98% RTP)
Arguably one of the most prominent slots to make our list, Blood Suckers is found all over the internet and is a solid release from Scandinavian casino software providers, Net Entertainment. In fact, this game is so popular that it is considered a benchmark in the vampire-themed slot genre, beaten only by Microgaming’s Immortal Romance. Even that famous Microgaming slot cannot trump the 98% RTP rate that Blood Suckers carries, though. Jam-packed with famous vampires such as Elizabeth Bathory, Dracula, Lestat and vague Nosferatu references, Blood Suckers is a 5-reel, 25-line slot and one which costs just 0.01 per line per spin. You can even slam down your stakes (no pun intended) worth up to 500.00 a spin if you wish.
Most major slots with high RTP rates generally tend to feature lackluster cash prizes. There’s none of that with Blood Suckers, though, which dishes out a non-progressive prize worth 7,500x your total bet if you’re lucky. The slot isn’t exactly short of special features, either. Expect to find wild symbols, scatters and bonus symbols. There is a click and win bonus feature in this slot which enables you to open coffins and either stake vampires to win cash or expose flying bets to end the feature. A free spin bonus has also been worked into its design, and this allows players a total of 10 free spins, during which all wins they may acquire a tripled courtesy of a 3x multiplier. If you’re after playing a truly epic best-paying online slot, Blood Suckers is right up there with the best of them.

Bridesmaids (Microgaming, 97% RTP)
We talked about Microgaming a moment ago, and now it is time to look at one of their best paying online slots. Bridesmaids is, of course, based on the famous motion picture of the same name, and features 5 reels and 40 pay-lines of action. Annie, Helen, Lillian, Megan and Rita all play their part to help players land wins worth up to 15x their total bet in this game, and while that does seem petite and wagers a bit costly (0.40 up to 60.00 a spin), the RTP rate of 97% ensures wins do occur frequently enough.
Bridesmaids offers up a stacked wild, but it is the cupcake symbols that most players will be after. This icon can trigger a wheel bonus. That wheel bonus can then deliver one of 6 bonuses. The simplest of these is a basic cash multiplier, with a jackpot bonus also up for grabs. However, there are also click and win photo and clothes bonuses, as well as two free spin features worked into the design of Microgaming’s Bridesmaids slot.

Columbus (Novomatic, 97.03% RTP)
Whether you fancy trying your hand at the original Columbus game, or its more extensive deluxe version, there are winnings to be had here. Columbus is a Novomatic slot, and it is one which isn’t shy about dishing out decent wins, with its 10,000-coin non-progressive jackpot and its 97.03% RTP rate. Wagers aren’t going to cost you a packet, either, stretching from 0.01 per line per spin up to 100.00 a game on the 5-reel, 10-line deluxe slot.
Understandably, Columbus himself appears as a wild in this game, which features primitive but not exactly dated graphics. There is a gamble feature which is rather primitive, but it is the free spin bonus which really stands out here. It is triggered by landing three or more of the sailing ship scatter icons on the reels. Once the bonus begins, players are treated to a total of 10 free spins. No other goodies have been pumped into this feature, though, so although Columbus and Columbus Deluxe are generously paying slots, they are as elementary as you’re likely to find in the online casino world.

Cosmic Quest: Mystery Planets (Rival Gaming, 98.95% RTP)
Rival Gaming makes its debut on our best paying online slots list with this effort, and what an effort it is. With an RTP rate of 98.95%, Cosmic Quest: Mystery Planets is widely regarded as one of the top five best paying slots of all time. The second in the Cosmic Quest series, this is a straightforward and basic game, and the graphics are quite subpar. None of that will matter to players, though, provided they land a semi-decent win on the reels. That is almost assured of happening since the return to player rate is so high. Wagers on this 5-reel, 20-line slot cost at least 0.01 per spin, and top prizes are non-progressive and capped at 5,000 coins in all.
Expanding wilds make an appearance in Cosmic Quest: Mystery Planets, and they also double up as the jackpot paying icons. Landing 3 more jet pack scatters can offer players up to 50 free spins with all wins doubled, and there is also a second bonus round in the game. That “Scatterstronaut” feature allows players to pocket instant win prizes via a rather basic click and win feature. It may not look like much, but the game can certainly deliver the goods once you get to grips with it.

Diamond Tower (Amaya Gaming, 97.04% RTP)
Released by Amaya Gaming, Diamond Tower is another simple slot. The theme here is lifestyles of the rich and famous mixed with a luxury heist, the graphics are 3D but cheesy and old-school, and the top prize is valued at around 2,000 coins. However, there are over a thousand pay-lines in this game (1,024 to be exact), so wins are frequent. Watch out for the wagers, though, as they cost at least 0.80 per spin and no more than 40.00 a spin, which is a little steep.
Players will also want to keep their eyes peeled for the wilds and scatters. Cat burglar wilds can replace all icons save for scatters, and those scatters can trigger a free games bonus. Firstly, players who land diamond icons on the reels will see those reels locked. They must lock all the reels to trigger the feature, which is tough stuff, too. In the Break-In Bonus, you can select doors to nab jewels (cash prizes), but when the red light is hit, players will be forced to accept free spins and multipliers. The final part of the bonus sees those spins played out with any multipliers won by the player.

Dinosaur Adventure (Genesis Gaming, 97.25% RTP)
Genesis Gaming’s Dinosaur Adventure may not have the most endearing name for a slot or the catchiest, but it does have a corking 97.25% RTP rate. It also offers 1,024 pay-lines for you to win on, and unlike Diamond Tower, those bets cost just 0.40 at their cheapest. A somewhat cheesy game, Dinosaur Adventure can deliver wins worth as much as 5,800 coins via its 5×4 reel structure. Both scatters and wilds appear in this game, with scatters being the most valuable symbols, which is a change.
A Dinosaur Free Spins feature is triggered by landing 3, 4 or 5 scatters. Up to 20 free games can be won, and players are at liberty to bag 2x to 4x multipliers when wilds feature on the reels during this bonus. Those wilds can also multiply against one another when they feature in winning combos, effectively giving you much larger multipliers than you might think, in what is an otherwise easy to grasp video slot machine game.

Doo-Wop Daddy-O (Rival Gaming, 97.99% RTP)
There are a surplus of 60s-themed slots out there on the net, but Doo-Wop Daddy-O is easily the best of them, and for more reasons than one. You would normally associate a Rival Gaming slot with that honour, but with fitting graphics and an RTP rate which is just shy of 98%, there is no denying that Doo-Wop Daddy-O is a groovy game. A spin on this 5-reel, 20-line slot costs anything from 0.01 (per line per spin) up to 25.00 a game, and there is a non-progressive prize worth 15,000 coins there for the taking. Who wouldn’t want a little slice of that?
There are more than a few special features for you to indulge in, too. Players will note that wilds and two scatters form the special symbols here. Car scatters will initiate an instant win-based Drag Race bonus, whereby players can win prizes based on how successful their chosen car turns out to be in a race. Meanwhile, milkshake scatters can trigger a Soda Fountain bonus. This offers players the chance to select ingredients to make a shake, and thus win more instant cash prizes. Curiously enough, there are no free spins to be had in this 60s-themed slot, although you don’t really need them when the return to player rate is this good.

Esqueleto Explosivo (Thunderkick, 97.06% RTP)
Arguably one of Thunderkick’s most popular slots, Esqueleto Explosivo was launched in 2014 and has rapidly become known for its above average RTP rate, its colourful graphics, and its Mexican Day of the Dead theme. Interestingly, the slot only features 17 pay-lines on its 5 reels, but players can get away with dirt cheap wagers, costing just 0.17 per spin and no more than 100.00 a spin. As for the top prize, expect to be able to win around a thousand coins with this non-progressive jackpot slot machine game.
There are a few features you want to check out here. Firstly, there is a collapsing reel feature here, whereby winning skull symbols will drop down and be replaced by new ones. This gives players a chance to land several wins per spin, especially since consecutive wins can lead to multipliers worth up to 32x being applied to your winnings. Explosive wilds can destroy adjacent symbols when they appear, too, which makes this slot even more exciting. Again, throw in the fact that there is a generous RTP rate (at 97.06%) into the mix, and you’ll want for nothing with this groovy Día de Muertos inspired slot.

Fruit Boxes (iSoftBet, 97.10% RTP)
Fruit Boxes is an iSoftBet developed slot and a particularly well-known one to boot. The game features crisp 3D graphics and is known for being one of the better-paying titles around. Players can expect to be able to wager with ease in this game, with a set of easy to use buttons allowing you to bet anything from 0.15 per spin up to 75.00 a game. There are, however, only 15 pay-lines straddling the slot’s 5 reels. One of the joys in this fruit-filled, mad monkey-themed slot is the exploding symbols feature, though.
Any winning symbols which appear on the reels will explode and be replaced by new ones. This cascading reels feature can potentially lead to an unlimited number of winning combos appearing on the reels. Three or more bonus icons will trigger a Fruit Box bonus, which could see players win up to 50 free spins, and scatters can dish out wins no matter where they fall on the reels of the slot. All in all, players can hope to win up to 5,000 coins with this non-progressive, barmy and simply delightful fruit-themed slot machine game from iSoftBet.

Fruit Warp (Thunderkick, 97.00% RTP)
Another fruit-themed slot, Fruit Warp has been produced by Thunderkick. This game features impressive 3D graphics, and these can cause the game to run a little slow on older systems. Fruit Warp doesn’t use pay-lines. Instead, players are required to win by landing clusters of symbols on the reels. Even so, wagers stretch from 0.10 per spin up to 100.00 a game. On the upside, the top prize is capped at over 200x your total bet, which no player will walk away from. Throw in a decent RTP of 97%, and wins occur often enough to satisfy all.
As for features, there are a few to be had. Players who land 4 or 5 of the same fruit symbols will dive straight into a Portal Re-spin bonus. It can see those fruit symbols remain on the reels, while others disappear and are replaced by new ones for the re-spin. In this manner, it is possible to bag several wins at the cost of just a single stake. Another feature is triggered by 5 symbols appear, and this involves collecting multipliers and having them added together to see you land more than generous wins in this creative and inventive fruit-themed slot.

Good Girl Bad Girl (BetSoft Gaming, 97.80% RTP)
BetSoft Gaming’s progressive jackpot slot, Good Girl Bad Girl, is quite unlike many other games you will find. This slot allows players to choose to play in Good Girl mode or Bad Girl mode. The mode you choose determines which prizes and features you can win. You can also choose to go straight down the middle in this game, which has an RTP rate of 97.80%. Pitchforks and Halos are wilds, though which you get depends on the mode you select. A select of Click Me feature have been included in this game, with both good and bad variants, depending on the mode, and there is a money wheel which could see you win one of the two progressive jackpot prizes.
Good Girl Bad Girl doesn’t just offer three gaming modes. It also allows players to choose wagers which range from 0.01 up to 75.00 a game. You can play with 15 paylines on this 5-reel slot, with wins running from left to right (Good Mode), right to left (Bad Mode) or in both directions (at twice the stake). If you’re after one of the best paying progressive online slots, then Good Girl Bad Girl could be for you.

Gung Pow (Microgaming, 97% RTP)
Chinese and Far Eastern-themed slots have been very popular for the last few years now. This game came out in 2014 and has been developed by Microgaming. Although they have several good paying slots, their games seldom expand their RTP rate beyond 97% which is what you want in this slot. Gung Pow features all the stereotypical symbols you would expect to find in such a slot, as well as Microgaming’s customary 243-payline structure over its 5 reels. Wagers cost as little as 0.25 a spin, but you can wager as much as a mind-boggling 1,250.00 per spin if you’re flush. All that hard work can see you win up to 120x your total stake if lady luck is with you.
The special features aren’t over the top here, with free spin icons appearing as tokens and they can trigger a bonus which offers up to 15 free games. Any winnings you land here are tripled. Disappointingly, wilds only appear on the second and fourth reels of this game, but aside from that, Gung Pow is a quality online slot machine.

Gypsy Rose (BetSoft Gaming, 97.60% RTP)
You have probably noticed that quite a few BetSoft slots have made our list. The casino software providers just seem to have a knack for delivering decent RTP rates in their games. At 97.6%, the same is true for their Gypsy Rose slot. This slot machine features the usual fantastic 3D graphics we’ve come to expect from them, is played with a fortune teller theme in mind, and can be played for anything from 0.02 per line per spin, up to 150.00 per spin. Top prizes are capped at a more than respectable 1,500x your total stake.
Gypsy Rose is not short of special features, either. Wild symbols landing on the first and fifth reels of the first, second or third pay-line will see the title character chuck a few more wilds your way. Landing crystal balls on the third reel will offer one of four bonuses in the game. These include a free spin bonus, a re-spin with frozen wilds, an instant win prize worth up to 20x your total stake, or a tarot card bonus which delivers further instant win prizes. As usual, there is a gamble feature worked into the design of this BetSoft Gaming developed online video slot.

Halloween Fortune (Playtech, 97.06% RTP)
Forget about the sequel; that’s poor. The original Halloween Fortune slot is a winner, though. The game which features a light-hearted take on Halloween and witchcraft and uses three sexy sprites as its main characters can deliver an RTP rate of 97.06% and a non-progressive jackpot which is worth a respectable 10,000 coins. All of that is ramped up in a 5-reel, 20-line format, with bets on this Legendary Playtech slot costing as little as 0.01 per line per spin and certainly no more than 20.00 a game.
One of the reasons is sequel sucked is that Playtech did away with the nifty features that this first game has to offer. Halloween Fortune contains a wild, a cash-paying scatter and a bonus icon. The cauldron appearing on the first and fifth reels offers up a click and win bonus, whereby players can select a sexy witch and potion to win free spins plus multipliers. Those choices are then played out in the subsequent free spin bonus round, which can really deliver immense cash prizes for such pithily stakes, courtesy of its overly generous RTP, as mentioned.

Hot as Hades (Microgaming, 97% RTP)
Another member of Microgaming’s 97% RTP club, Hot as Hades debuted in 2015 as a tongue-in-cheek version of the classic Greek mythology slot. Hot as Hades offers 20 lines over its 5 reels and it will cost you at least 0.20 per spin since you cannot adjust the lines in the game. Wagers won’t set you back more than 50.00 a pop here, though, with prizes worth up to 100x your total stake there for the taking. If you play with the maximum stake, you could possibly win as much as 100,000 coins in this Greek mythology-themed slot.
Wilds are doubly useful here. Not only will they substitute for all other icons save for scatters, but they can also double the value of all winning combinations in which they play a part. At any point in the base game, a randomly triggered feature may occur which delivers 5 free spins and extra wilds which can be frozen in place for the duration of the bonus. Keep your eyes peeled for the crystal skulls, too, since these can trigger a bonus in which players can select items to win instant cash prizes, based on a four-tier bonus round. Provided, of course, players manage to avoid the one object which terminates the bonus.

Hot Ink (Microgaming, 97.50% RTP)
Edging just above Hot as Hades in Microgaming’s high paying slot group is Hot Ink. Truth be told, the game play in the tattoo-themed slot is rather drab and dull, but none of that matters if you are just after playing the best paying slots online. Hot Ink delivers in an impressive 1,024 pay-lines over its 5 reels and costs anything from 0.50 upwards for a spin. The non-progressive jackpot is not to be baulked at, either, standing at a fair 1,000x your total bet in all.
Hot Ink’s features are plentiful but dull, as we’ve said. Players can re-spin the reels following any spin to try and land second chance wins, but those re-spins will cost you. This feature did not take off for Microgaming. Moreover, the slot – which has an RTP rate of 97.5% also offers up a mundane Tattoo Bonus. In that feature, players can select a tattoo book to possibly win free spins with 2x multipliers or an instant cash prize. The main spins bonus is triggered by landing koi fish icons on the reels and can see players pocket double wins over 20 spins with this feature. Why koi fish icons? Your guess is as good as ours.

Hound Hotel (Microgaming, 97.00% RTP)
Staying with Microgaming for the time being, we come to Hound Hotel. As its title suggests, this is a game which is all about dogs and hotels. Simple enough to grasp, right? Admittedly, that theme may not tick many players’ boxes, but the 97% RTP rate will, just like the 100x your total bet jackpot prize. Hound Hotel features just 25 lines over its 5 reels, and players can expect to find a wagering range which has a floor of 0.25 and a ceiling of 1,250.00 a spin.
Wilds can appear stacked in this slot, although on a non-winning spin, Dashing Wilds may appear, which can give you a second chance to bag a prize. As for the primary bonus, that is known as the Hound Hotel Bonus (rather unimaginatively, we might add). In this feature, players can try and work their way through the three floors of the Hound Hotel to win goodies. The first, second and third floors offer special wilds, multipliers, and the number of spins you will start the bonus with, respectively. Special wilds include stacked, expanding, frozen, split wilds, and wild reels. This feature is the highlight of the game.

Jack Hammer 2 (Net Entertainment, 97.10% RTP)
Jack Hammer 2 is marginally better than its predecessor. Why? Well, Jack Hammer may have an RTP rate of 97%, but its sequel coughs up a 97.10% RTP rate. Every little helps, right? In Jack Hammer 2: Fishy Business, players are treated to the same kind of game-play which made the original such a hit. There are 5 reels to play with and a cool 99 lines to bet on, all yours for a minimum stake of 0.50 per spin. Prizes range up to 500x your total bet in value, but that’s not all…
Players will note that whenever winning symbols appear on the screen, they will be frozen, and new ones will replace the other symbols on the reels. If you keep adding to those winning combos, the Sticky Wins feature keeps on handing out re-spins. A free spin bonus round has also been included in Jack Hammer 2: Fishy Business, and it is activated when 5 or more scattered electric eel symbols appear. Players can win up to 20 free games with those, during which any winnings are doubled, and a random wild is added to the reels on each spin. If you were to land the Sticky Wins feature here, wins will flow, hence the generous RTP rate found in the game.

Jackpot 6000 (Net Entertainment, 98.86% RTP)
Arguably one of the most appealing classic slots on the net, the Scandinavian online casino software provider’s Jackpot 6000 has a remarkable return to player rate of 98.86%. This is baffling for a 3-reel, classic slot. There are 5 paylines on those 3 reels, and bets cost anything from 1.00 up to 10.00 in all. That may sound rather steep, but you can win up to 2,000x your total stake with this NetEnt developed classic slot.
Following a win in the game, your winnings are transferred to the Supermeter. Once there, players can choose to collect their prize or gamble them. If they choose to gamble them, any combo featuring two jokers will see players win a mystery prize. It is worth noting that Jackpot 6000 has this superb RTP when a 10-coin bet is made. However, if you bet less than that, the RTP drops to a shockingly low 74.9% to 95.1%. This is a game which you only want to play with 10-coin bets, and it is imperative that you remember that.

Jokerizer (Yggdrasil, 98% RTP)
The Jokerizer is a classic/video fusion slot from Yggdrasil, and an excellent example of one which has been designed rather well. The game is hugely popular across the net and can be found in most major casinos. What you have here is essentially a fruit machine but with video slot features, including 5 reels and 10 lines. Wagers are steep, ranging from 1.00 up to 20.00, but with an RTP rate of 98% and wins worth as much as 400x your total bet, they are worth it. The RTP rate is unusually high in this game because there are so few symbols to get in the way of you landing a winning combination.
Players who land 3 jokers on the inner reels will get to land a mystery win prize, worth up to 6,000 coins. A Jokerizer Round can be triggered following any win, and it can see players collect their cash or transfer them to the big reels. You’ll stand a good chance of winning on these reels, and the prize is yours if two jokers appear. This slot is very similar to Jackpot 6000 in that sense.

Jungle Spirit (Net Entertainment, 97% RTP)
Onto another Net Entertainment developed slot now, in Jungle Spirit: Call of the Wild. Launched in 2017, this game features gorgeous animal imagery, and as its title suggests, wilds are plentiful in this game. So too are pay-lines, with 243 of them present on its 5 reels, all for a low stake of just 0.20 per spin. Top prizes are valued at 150x your total bet in this game, which has an RTP rate of 97%, making it a firm favourite with many slot players.
Even though wilds do not make an appearance here, there are ample ways to win. Winning symbols which feature butterflies can expand to cover entire reels, and there is a randomly triggered bonus round in which butterflies can fly and land on symbols to trigger the same feature. The game also includes a free spin bonus which is triggered when 3 or more pink flowers appear on the screen. Players can select from 5 different free spin bonuses, with each bonus offering a varying number of spins. However, the bonuses with fewer spins provide a greater chance of landing wins, so that is something to think about when playing Jungle Spirit: Call of the Wild.

Kitty Cash (1×2 Gaming, 97.90% RTP)
The first of two cat-themed slots to debut on our list of the internet’s best paying online slots is 1×2 Gaming’s Kitty Cash. Cute and cuddly is perhaps the best way to describe this slot, with its cheeky but elementary graphics. 1×2 Gaming aren’t the most noticeable of software providers, but they have still managed to turn out a 5-reel, 9-line slot which costs a pittance (0.05 per spin) to play, delivers a non-progressive jackpot worth 750x your stake, and comes with an RTP of 97.9%.
The slot isn’t shy when it comes to special features, either. Wilds can double any winning combinations in which they play a part, and scatter icons can be used to trigger free spins. Up to 25 free games can be won with this feature. Admittedly, the free spin bonus is a little bland, with no further goodies thrown into the mix, but with wins frequently appearing, you should have all you need to make the most out of this single bonus round in Kitty Cash.

Kitty Cabana (Microgaming, 97% RTP)
The second of our feline-themed slots is Kitty Cabana. Microgaming debuted this slot back in 2015, and although it isn’t one of their hottest titles, it is a big winner in terms of what it can deliver to you. A 25-line slot, Kitty Cabana is what you would expect to find if cats enjoyed a vacation in Cuba and given that it costs just 0.25 per spin and offers up a non-progressive worth 100x your total bet, there are plenty of reasons why you may wish to take a day or two off yourself to play this Microgaming slot.
Wilds appear stacked, and that’s very nice, but Dashing Wilds are the key to success here. They can occur at any time (at random), and they can chuck as many as three wilds onto the reels to potentially help you land a win. The Kitty Cabana bonus works in the same way as the bonus feature in Microgaming’s Hound Hotel. Players can work their way through three floors, to land special wilds, multipliers and free spins, which are then played out accordingly. Special wilds include stacked, expanding, frozen and split wilds, as well as wild reels. All in all, you’re spoilt for choice in this slot, which for some strange reason, just hasn’t lived up to the hype.

Lucky Lady’s Clover (SoftSwiss, 97.31% RTP)
SoftSwiss are not known for their superior software, but this small developer does power many casinos with their in-house software. Lucky Lady’s Clover is arguably their finest slot if you’re looking for a game with a high RTP rate. At 97.31%, this Irish luck-themed game has it all. Bets can cost as little as 0.01 per line per spin, and a non-progressive jackpot is capped at 10,000 coins. As is often the case with online slots, several handy features have been included in the design of this game.
For starters, players can expect to find a wild which can replace all other icons (save for scatters) and double any wins you have. Scatters can dish out wins if just two appear, and three will trigger a free spin bonus. In that feature, up to 15 games can be won with any winnings you happen to acquire being tripled. A gamble feature wraps up the set of bonuses (if you can call it a bonus) that you can expect to find in this great, green-coloured slot game.

Lucky Mermaid (MultiSlot, 98.50% RTP)
MultiSlot are the tiniest of casino software providers, so you wouldn’t ordinarily associate them with being able to churn out a whopper such as this. Lucky Mermaid may sound basic, it may look basic, and let’s face it, it is basic; but the game does have the potential to see you win big and frequently, with its 98.5% RTP rate. Lucky Mermaid features just 25 lines over its 5 reels and bets stem from 0.25 upwards.
Features are, however, somewhat few and far between in this game. Players can expect to prosper from wild symbols in the slot, and the seahorse is the icon which acts as those substitute symbols. As for other bonuses, there is just one. Three or more logos will trigger a click and win bonus, whereby players can select a mermaid to see if they win a race. Cash prizes are dished out based on the selection and the outcome of the race. Admittedly, Lucky Mermaid is as boring as slots come, but with regular wins shooting out left, right and centre, players who are after the best paying online slots may wish to overlook that, given that there is a house edge of just 1.5% in this game.

Mega Joker (Net Entertainment, 99% RTP)
Mega Joker holds the record for being the best paying online slot game currently available. With an RTP rate set to 99%, it is impossible to find a better paying slot right now. Developed by Net Entertainment, Mega Joker launched in 2013 and is a 3-reel, 5-line slot. It costs anything from 1.00 up to 10.00 a game and boasts a progressive jackpot to boot.
The main feature in this slot is triggered whenever a player lands a win. They can collect their winnings or transfer them over to the Supermeter. This is played out on an upper set of reels. To get their hands on the progressive jackpot cash prize (which in the past has been worth hundreds of thousands of credits), players need to do nothing but spin. The top prize is paid out at random. Of course, the larger your bets happen to be, the more likely you are to walk away with a life-changing sum of money. However, as mentioned, with an RTP rate of 99%, wins occur frequently – very frequently – in this NetEnt produced classic slot.

Mystery Joker (Play ‘N Go, 97% RTP)
You’ve probably noticed that quite a few slots on our list carry RTP rates of 97%. Anything less and slots would go from being among the best paying online to average. Mystery Joker fits into our list not just because of its RTP rate, but because it is easy to play. The game offers 3 reels and 5 lines, with players forced to bet anything from 0.50 up to 100.00 a spin. Jackpot prizes are small at just 50x your total bet, but wins occur with shocking regularity.
You wouldn’t think that a classic slot machine (or a fruit machine, if you prefer) would come with a bonus round such as a free spin feature, but this one does. Play ‘N Go have included one here which is triggered by landing 3 jester hat icons on the reels. Once the bonus begins, players prosper from 10 free spins. During the feature, landing just 2 scatters will see players pocket an instant cash prize worth up to 100 credits. Land 3 to bag a mystery win cash prize and add another 10 free spins to your tally. Up to 50 spins can be won in this fashion with the Mystery Joker slot machine.

Pipezillas (GamesOS, 97.20% RTP)
Pipezillas is probably a game you won’t have come across when playing online. Developed by small-scale software providers GamesOS, it is somewhat of a reclusive game. The game can be played for as little as 0.01 per line per spin and offers a return of around 200x your total stake if its non-progressive jackpot is struck. The theme of this slot is as barmy and zany as its title. Expect to find a host of weird and bizarre critters which apparently live in your pipes, with one very strange critter acting as a plumber. GamesOS certainly gets an A+ for originality here.
Wild symbols simply replace other standard paying symbols, unless, of course, they land on the third reel. Then, they can expand to cover the whole reel and offer a 3x multiplier to any wins in which they play a part. A free spin bonus is triggered via scatter symbols, and up to 15 spins can be won here. Lastly, a Pipezilla Race Bonus can be triggered if players land 3 or more blue monsters on the reels, but on a pay-line. This feature allows players to select a potential winner. The amount they win depends on the outcome of the race and the character they chose.

Ragnarök (Genesis Gaming, 98% RTP)
Known fully as Ragnarök: Fall of Odin, this Norse mythology-themed slot is based on the Viking end of the world (Ragnarök). Developed by Genesis Gaming, the slot has a varying RTP rate, but at its highest it can be 98%. The RTP varies, depending on the Rune Level a player has obtained. In short, the more you play the game, the better the RTP rate gets in this slot, which can dish out wins worth up to 1,000 coins via wagers costing as little as 0.01 per line per spin.
Players can collect runes randomly after base game spins, and when features are triggered. The number of runes you collect determines your Rune Level, as well as the features you have open to you. The levels include Thor vs Jor (Level 1), Freya vs. Surtr (Level 2) and Odin vs. Fenrir (Level 3). Features included in this game (though distributed across the various Rune Levels) include free spins, multipliers ranging from 3x up to 22x, extra wilds, instant win prizes, and more. It may sound complicated but stick with Ragnarök, because the more you play, the more it is worth your while.

Rags to Riches (Cryptologic, 97.95% RTP)
One of the most famous slots of all time is Cryptologic’s Rags to Riches and it is also one of the best rtp slot machines. This 5-reel, 20-line slot tells the tale of a nobody who went on to become a somebody. That is ideally what the developers want you to believe will happen to you, and with an RTP rate of 97.95%, it can happen. Wagers range from 0.05 up to 400.00 a game here, which isn’t bad for a slot with a non-progressive prize worth 25,000 coins at stake. You know, that’s provided you don’t win the slot’s progressive jackpot.
Even though there are no wilds symbols present in the game, players can still enjoy special features. Rags to Riches scatters can trigger a bonus round whereby players can select whether the next number in a sequence will be higher or lower than the displayed one. Work your way through the numbers, and you end up winning big money. Get all the way to the end to win the progressive jackpot. However, two mistakes and the bonus round ends for you. This is a tricky progressive to win, but even without it, the RTP rate ensures decent wins aplenty are available to be had with this game.

Rambo (iSoftBet, 97.02% RTP)
Rambo is, of course, based on the famous film series of the same name, starring Sylvester Stallone as John Rambo. A Vietnam War veteran with a knack for war, Rambo is well portrayed here. In fact, the entire game is a faithful recreation of the film franchise. Expect 720 paylines to be present in this 5-reel iSoftBet slot, with bets ranging from a reasonable 0.50 per spin up to no more than 12.50 per spin. You can’t really argue with those bets given the RTP rate, especially when progressive prizes are up for grabs.
Wilds are standard in this game, but scatters can trigger a free games bonus. In that feature, 1 symbol is selected at random to be an expanding icon. Additional free spins can be won in the bonus, and grenade symbols can trigger a progressive jackpot prize. Players need 5, 6, 7 or 8 to win the Stealth, Bravery, Honour and Explosive Jackpot prizes. Notably, the progressives can be won in the base game as well as the free spin bonus, giving you ample chances to walk away with a life-changing sums of cash.

River of Riches (Rabcat, 97% RTP)
Rabcat have developed the River of Riches slot, and it has been made available on Microgaming’s Quickfire platform, like many of their other games. The slot machine is naturally one of many Ancient Egyptian-themed games which you can find online. However, it is the best paying one in this genre to make our list. River of Riches offers 5 reels and 25 lines to play on, with bets fluctuating from 0.01 per line per spin up to 50.00. Prizes are petite at just 40x your total bet, but the high RTP rate ensures wins are at least occurring with regularity.
Keep your eyes peeled for the scatters. These symbols can dish out wins for just 2 icons but can trigger a free spin bonus when 3 appear. Prior to that, though, players will get to learn how many special wilds will be added before each spin. Those extra wilds boost the level of excitement in your game and can make River of Riches even more prosperous. A gamble feature has also been included here, but it is best to stay away from that since you a 50% chance of success of less with the gamble mode.

Safari Sam (BetSoft Gaming, 97.50% RTP)
Safari Sam is one of the most likable (and cute) slots ever devised by BetSoft Gaming. An intrepid explorer and the jungle girl known as Sam take centre stage in this safari-themed slot, which has a wonderfully generous RTP rate of 97.5% meaning it is one of the best rtp slots online. Being a typical BetSoft Gaming developed slot, there are 30 fixed lines, and bets range from 0.02 up to 150.00 a game, while prizes are capped at the customary 500x your total bet mark.
If symbols appear fully stacked on a reel, they can collapse into the same icon following a win, and new ones will drop down to replace some of them in a collapsible reel feature. The game also distributes random wilds onto the reels which can add multipliers worth up to 10x to your wins. Landing the gorilla, zebra and monkey icons in this game will dish out free spins with 2x multiplier wilds. Lastly, a pick and win bonus can see players choose a place for Sam to go, whereby she will locate animals to dish out instant win prizes until the predictable collect sign terminates the bonus round.

Serengeti Diamonds (Amaya Gaming, 97% RTP)
Another member of the 97% club, Serengeti Diamonds is Amaya Gaming’s take on an African safari slot, and it is a rather poor one at that. Played over 5 reels and 25 lines, this slot features poor graphics which don’t push its underwhelming theme at all. However, Serengeti Diamonds does have a generous RTP rate and can deliver wins worth up to 5,000x your total stake. Stakes are costly, though, ranging from a floor of 0.50 per spin, up to 125.00 a game if you’ve got cash to splash on this slot.
Scatters can trigger bonuses, and wilds can replace all but scatters, but you probably knew that already. The Diamond Pick Bonus is triggered by landing scatters on adjacent reels, and they will then remain frozen on the reels while re-spins occur. If you land further diamonds, you’ll bag more re-spins. Bag all diamonds on adjacent reels, and you can select two to win between 5 and 10 free games with between 3x and 8x multipliers for those spins. It is all very dull, drab and boring stuff, but if you want a slot with a great RTP rate and one which pays out frequently, you may still be interested in what Serengeti Diamonds has to offer.

Steam Tower (Net Entertainment, 97% RTP)
Steam Tower is arguably one of Net Entertainment’s more frequently played games, so most players will already know by now that it carries a return to player rate of 97%. That’s not all, though. Steam Tower also carries a non-progressive jackpot which is capped at 2,000 coins. Wagers are cheap at 0.15 per spin and up, and the theme of this game is truly unique and original. Expect a steampunk, dragon, damsel in distress theme to captivate you as you play.
The theme isn’t the only original feature in the game. The bonus round is also right up there in terms of creativity. It is triggered by landing stacked wilds on a reel. Players will start with a total of 10 free spins, but they can ascend the Steam Tower floor by floor, landing more prominent and better prizes, multipliers and more free spins along the way. The objective is to rescue the damsel from a dragon. Doing so will see you win massive riches, but it is certainly not an easy ride. It is just as well then that there are plenty of other ways to win here.

Sugar Pop (BetSoft Gaming, 97.60% RTP)
Sugar Pop is yet another BetSoft Gaming developed slot make our list. A popular title, to say the least, Sugar Pop doesn’t play like your average, run-of-the-mill slot. Instead of pay-lines, players are required to land clusters of candy-like symbols to win prizes. By landing symbols in specific patterns, they can climb through levels, unlocked numerous goodies as they go in this slot, which costs anything from 1.00 up to 250.00 a game.
On your travels up through the levels, you can expect to land various sweets and chocolates which can influence your game. Some destroy rows or columns of symbols, and others offer multipliers on specific coloured symbols. Locate the words bonus pattern and fill the spaces on the grid and you can advance to the next level, where the goodies get better and better. If this all sounds too complicated, just imagine what Candy Crush Saga would be like if you could play it for real money, with the potential to win real money, and you’ll have hit the nail on the head with this BetSoft Gaming video slot.

Supernova (Quickspin, 97.50% RTP)
Developed by Quickspin, Supernova is undoubtedly a bizarre slot, and that (alongside its 97.5% RTP rate) is why it makes our list of the best paying online slots. The game is played in a 3×3 grid, with a second 3×2 grid located to the side of those reels. The latter can offer multipliers, while the main reel set is where the action takes places. That action will cost you at least 0.20 per spin but no more than 50.00 a game. Prizes are petite at 50x your total bet, and although it takes some getting used to, Supernova is well worth a look.
Supernova offers up 27 pay-lines over its 3 reels, well, 5 reels, really. Although there are no bonus rounds to be had when playing this game, players will note that the second set of reels becomes active win a win occurs. These second set of reels could see players win multipliers worth between 2x and 10x the normal rate of pay or they can land on a black hole and not add multipliers to their winnings. That’s all there is to Supernova, really. It is as simple as that.

Temple of Luxor (Genesis Gaming, 97.10% RTP)
Genesis Gaming’s Temple of Luxor is one of the more baffling slots you’ll come across, at least in terms of interface. There are 10 reels in all, divided in the middle by an obelisk. One hundred pay-lines (50 per reel set) span those reels and wins can come from left to right or right to left, depending on the reel set the symbols appear on. Players are looking at betting anything from 1.00 up to 10.00 a game here, but they can win up to 200x their stake courtesy of an RTP which sits at 97.10%.
If you happen to trigger the bonus (by landing two ankh icons on the left and right reels), that obelisk that divides the reels becomes a special 11th reel, linked the two sets of reels together. Players will now find that they now have 11 reels and 50 lines (which pay each way) to get to grip with. This massively ramps up the RTP rate to the figure we have listed here, and with this expanded reel set, it is possible to win as much as 5,000 coins by lining up 11 Horus symbols on any of the slot’s paylines. Temple of Luxor is, therefore, undoubtedly worth a look.

Tiara (Merkur Gaming, 97.81% RTP)
Merkur Gaming are not everybody’s favourite casino software developer. They often produce games which are far too basic to be of any real enjoyment. Nobody was grumbling when they unveiled Tiara, though, with its 97.81% return to player rate. This game is, essentially, a fruit machine, like most other slots from this developer. However, playing with 10 pay-lines and 5 reels does make it simplistic, even if it is cheap to play at just 0.10 per spin. How basic are we talking here, then? Well, you only need to look at the special features to find out.
There are none. Well, that’s not entirely, true. There is a wild symbol. Wilds can substitute for all other symbols, and they can expand to occupy whole reels. When they do this, a free re-spin is granted to players, but that’s their lot. As pathetic as that sounds, what you must remember is that Tiara pays out regularly, very regularly, and at the end of the day, that’s all we’re looking for when it comes to the internet’s best paying online slots, isn’t it? Given its lack of features, Merkur Gaming’s Tiara is best suited to players looking for a big paying game but none of the hassles of special features then.

Vegas Dreams (Big Time Gaming, 97% RTP)
The penultimate game in our list is also the first entry from Big Time Gaming (BTG). Vegas Dreams is a crazy Vegas-themed slot and one which comes complete with flash cars, chips, dice, and every other item you might associate with Sin City. Vegas Dreams looks a lot more complicated than it is, with bets on this 5-reel, 20-line slot ranging from 0.01 up to 250.00 a game. Prizes are excellent at 10,000 coins, and the RTP rate is 97%, so there’s no grumbling there.
When players land a slot machine scatter, they will initiate a free spin bonus. Wild symbols appear as roulette wheels and can double the value of any winning combinations they assist in making. Back to the free spin bonus, Vegas Dreams ensures that players are granted to 15 free games, and anything they win will be tripled, courtesy of a rather generous 3x multiplier. You can also re-trigger the feature in this simple, enjoyable and rather standard video slot machine game.

Wheel of Fortune: Triple Action Frenzy (IGT, 97% RTP)
We’ll end our list of the best paying online slots with IGT’s first game on the list, and the final member of what is rapidly becoming an overcrowded 97% club in terms of return to player rates. Wheel of Fortune: Triple Action Frenzy is one of many Wheel of Fortune-themed slots out there, and this one delights in offering a tropical-style to its imagery. Players will find wagers ranging from 0.15 up to 75.00 on this 5-reel, fixed 15-line non-progressive slot, which can deliver wins worth up to 1,000x your total bet in all.
What about its features? Wheel of Fortune: Triple Action Frenzy features both wilds and super wilds for starters. The latter can appear on the third reel and turn into a set of envelopes. Pick one and you can win a multiplier worth up to 5x which will be applied to any wins you land. The game also comes with its titular Triple Action Bonus, triggered by landing bonus icons on the first, second and third reels. In this feature, players can try to complete a game of hangman to land a multiplier. After that, players can spin the Wheel of Fortune to win a cash prize in what is a decent take on the original and hit television game show.
