Enjoy some cartoon-style martial arts mayhem in Thunderfist, a 5 reel, 243 ways to win slot powered by Net Entertainment. This kung fu crew come with stacked wilds and a bonus feature that awards up to 20 free spins where payouts are boosted by random multipliers of between 2x and 5x. Play from between 25p and £125 per spin.

The visuals in Thunderfist are well constructed – set against a forest backdrop, the base game reels are enclosed within bamboo and include stylised playing cards from A to 10 alongside 5 martial artists. The most rewarding of these is the headband wearing man in orange who’ll get you 100 coins if you land a 5 symbol combo.

That may sound a little skinny but remember that Thunderfist uses the 243 ways to win game engine where winning combinations are created by landing the same symbol on adjacent reels. Joining the standard symbols is the stacked wild which can appear on any reel and substitutes for all other symbols apart from the scatter.

The golden coin is that scatter – it’s the key to unlocking the game’s main attraction, the Free Spins feature. 3 gold coins will get you 10 free spins, 4award 15 with 20 on offer if you’re lucky enough to land 5 coins. The free spins are played on a new set of reels, set within a temple or pagoda. The payout structure remains the same though.

You can boost your pay days during the feature courtesy of a random multiplier – after each winning spin, flashes of lighting will crash down to reveal a multiplier of 2x, 3x, 4x or 5x which will be applied to your win. The precise amount changes following each successful spin.

The design in Thunderfist is pretty high end which is what you’d expect from a slot from NetEnt – the cartoon animations are nice and smooth and the backing track certainly enhances the martial arts theme.

On the variance scale, Thunderfist sits somewhere in the medium range – the stacked wilds can certainly help things along in the base game. The free spins aren’t the easiest to trigger but the potential 5x multipliers can make it worthwhile when they do hit.

Thunderfist is a fairly simple slot – the sound and imagery are top notch and the features are perfectly solid. There’s nothing especially ground-breaking on offer but the stacked wilds, free spins and multipliers are an enticing combination and make Thunderfist well worth a look for martial arts and Asian-themed slot fans. If you like the theme, iSoftBet’s Red Dragon Wild is highly recommended.
