Thunderstruck I

About Thunderstruck I

Thunderstruck I is a five reel, nine payline, and forty-five coin slot machine, with:

A wild, multiplier symbol.
A scatter symbol.
A Free Spins bonus game.
A Gamble feature.

Game Payouts
Winnings paid out on the slot machine are dependent on the symbols displayed on the payline, once the reels have come to a stop.

Regular Payouts

All payout tables display the number of coins that are won for each combination. The total number of coins paid out depends on the number of coins you play per payline.
Regular wins are calculated by taking the number of coins won, multiplied by the number of coins played per payline.

For a combination of regular symbols to produce a winning regular combination, the following criteria must be met:

The symbols must be next to each other on an enabled payline.
Regular winning combinations pay out from left-to-right, so one symbol must be displayed on the first slot reel. A symbol combination starting from the second, third, fourth or fifth slot reel does not pay out.

Scatter Symbol Payouts

Scatter wins are calculated by multiplying the scatter symbol combination payout by the total number of regular coins bet.
Scatter wins are added to regular wins. If you have a scatter win and a regular win, you are paid out for both wins, as the scatter symbol does not need to appear on an enabled payline to win.
For a combination of scatter symbols to produce a winning scatter combination, the following criteria must be met:

Completes a winning scatter combination when two or more appear on the reels.
Cannot be substituted by the wild symbol.
