Thunderfist is a 5-reel video slot based on a 243 Ways To Win system whereby winning combinations are formed by a certain number of symbols landed on adjacent reels starting at the utmost left reel, not across a preset payline pattern. There are two bet options: a coin denomination ($0.01–$0.5) and a bet level (1–10), so the minimum and maximum bets are $0.25 and $125 accordingly. To place the maximum possible bet at your preferred coin value, you need to click the Max Bet button. The first, second and third largest bet way wins are $500, $375 and $250.

Bonus features

A wild symbol available in the slot comes stacked and can occupy one, two or all symbol positions on the reel it is on, thus creating more possibilities for a winning combo. The downside to the wild is that it does not create its own combos.

A scatter activates 10, 15 or 20 free spins if three, four or five scatters occur on the reels, no matter their position. During the free spins, all payouts are increased by a random multiplier of x2 to x5 that changes each spin.
