Aussie developer Ainsworth is inviting slots players to take another rainforest adventure, this time in Big Thunder Quad Shot. It’s a 5 reel, 25 payline game that comes with a free spins feature where multipliers can boost payouts by 3x or even 5x. There are also jackpot prizes of up to £10,000 up for grabs. Play on all devices from between £1.25 and £25 per spin.

There’s a strong jungle theme on display in Big Thunder Quad Shot. The lower value royal symbols are covered in creepers. They’re joined by a totem mask, a snake, a tribal shield and a drum. Top of the payers is the waterfall. Land 3, 4 or 5 of these on a line and you’ll receive an award of 0.2, 4 or 12 times your total stake.

Appearing on the middle 3 reels only in the base game is the gorilla which is the wild. This replaces all other symbols with the exception of the scatter. Land 3, 4 or 5 scatters (the Big Thunder logo) and you can look forward to a payday equal to 5, 20 or 100 times your stake. You’ll also activate the game’s Bonus Reel feature.

Once in, you’ll receive 15 free spins on a new set of reels which is missing the lower value playing card symbols. Hope to see the 3x and 5x multiplier symbols land in the Bonus Reel to the right of the main set. These boost the payouts by 3x and 5x whenever they appear.

There are a few amendments to the paytable in the feature too. The scatter awards up to 200 times your stake and the wild gorilla delivers payouts in its own right. You can add more free spins to your tally (in chunks of 5) if you land 3 scatters on the same free spin.

You’ll also have the chance to land a Mini, Minor, Maxi or Major jackpot. Hit a 5 of a kind winner plus the Quad Shot Bonus symbol and you’ll hit the jackpot. Which prize you get depends on the symbols in your 5 of a kind combo and whether it includes a jackpot. Prizes here are £50, £200, £1,250 or £10,000.

Big Thunder Quad Shot keeps to Ainsworth’s usual recipe. The design is functional without being beautiful and the gameplay is simple. The multipliers spice up the feature and there’s always that jackpot in the background. If you enjoy Ainsworth slots, then Big Thunder Quad Shot should offer plenty of appeal.

If you’ve not succumbed to the Ainsworth charms, then we don’t think Big Thunder Quad Shot offers enough to win you round. Head to jungle with better slots including NetEnt’s Jungle Spirit: Call of the Wild.
