Big Thunder Introduction

With a lush background of jungle foliage and reel symbols including an African drum, a waterfall, a snake, a shield and a mask, there is no doubt where this pokie is set: deep in the jungle. The lower paytable symbols are the familiar 9 to A, and you’ll earn up to a 5x multiplier when you spin up a full house of the highest-paying symbols.

However, this game is all about Big Thunder himself, the mighty silverback gorilla. He’s the wild here and although he doesn't pay out, he’ll help you land some very tasty winning combinations.

Winning ways

This Ainsworth pokie is fully customisable, so you can play it your way. Choose from 1, 2, 3, 5, 10, 15, 20, or 25 paylines with bets ranging from 0.30 credits to 100 credits for a maximum stake of 3,000 credits per spin, making this a high roller's delight. The maximum payout available in base gameplay is a 200x multiplier for five drums or waterfalls, but the real riches in Big Thunder can be won during the bonus rounds.

Big Thunder, big reel action

You trigger the bonus spins round by hitting between three and five Big Thunder logo scatters, achieving a reward of 2x, 20x or 50x your original line bet and 15 free spins. So far, so good, right? Big Thunder changes it up by adding an extra reel to the gameplay with 3x and 5x multipliers, removing the low-paying card symbols and ramping up the top paytable reward to 70x Big Thunder himself.

Hit six scatter symbols, and you’ll earn a 200x multiplier and retrigger the free spins bonus up to an additional 30 free spins. The biggest bonus in Big Thunder is awarded through the special bonus reel that spins up a jewelled crown every now and then.

Land the right combination of game symbols and crown, and you could be looking at the 100,000-credit Major bonus when you land five mask, drum, snake, waterfall or shield icons plus a crown symbol on the bonus reel. Different combinations of symbols with the crown will unlock the mini, minor and maxi bonuses.

Big Thunder in the wild

If you enjoy playing pokies at your desktop, Big Thunder will play straight from your browser without the need for any downloads. Do you prefer your gaming in the wild and on the move? Pokies 4U has fully optimised iOS and Android versions of Big Thunder so you can enjoy a little mobile jungle fever on your tablet or smartphone.

If you enjoy great graphics, big bonuses and the adrenaline rush of playing something a little out of the ordinary, Big Thunder is a must-play pokie.
