Big Thunder Slot - NZ Review, Demo Play, Payout, Free Spins & Bonuses

Down in the jungle

Featuring a lush rainforest setting and some nice animations when you hit the Gorilla wild, Big Thunder from Ainsworth is full of appropriate game symbols - an African Drum, a Mask, a Shield, a Snake and a Waterfall - that offer up to a 5x multiplier for a full house across the reels. The mighty Gorilla wild does not offer any multipliers when you land him, but he will help you pick up some winning combinations, and he’ll even beat his chest while he does it!

At the bottom of the paytable are the usual card symbols, which look slightly out of place with their dice and crown decorations. The Big Thunder logo scatter is the biggest-paying symbol on the reels, landing you 15 coins for a full house. There are some 3x and 5x multipliers available, along with staking options to suit everyone, from 0.30 coins a line to 3,000 coins to satisfy those that like to take a bigger risk.

Wilds and scatters

The Gorilla is the game’s wild, replacing all other symbols except the scatter to create some excellent winning opportunities during the game. The Big Thunder scatter carries a set of multipliers - 2x, 20x, or 50x for 3, 4, or 5 symbols on your reels - and also triggers the 15 free spins of the bonus round.

This bonus breaks out of the traditional reels, discards all the card symbols and adds an extra reel. The paytable gets tastier, and now that proud Gorilla nets you a 70x multiplier. However, it’s that sixth reel that really ups the ante with the gameplay as it carries a 3x and 5x multiplier. Land it, and you can trigger a winning multiplier up to 200x your original stake. Want more? Those free spins can keep triggering up to 30 in total!

Mini, Minor, Major or Grand jackpots

In base play, you’ll notice an extra reel where you can land an additional crown symbol. Earn yourself a full house and match it to a crown symbol, and you’ll trigger an extra jackpot; whether it’s Mini, Minor, Major or Grand depends on the colour of the jewel in the crown.

Big Thunder, big fun

Is it worth following this slot deep into the jungle? With all the treasures on offer, we say it certainly is. The extra reel during base gameplay adds a layer of intrigue along with those four crown jackpots, and the bonus round with those 3x and 5x multipliers delivers some excellent opportunities to increase your wealth.
