Big Thunder » Demo Slot » Ainsworth Games

Big Thunder is a video slot from Ainsworth Technologies, and it’s one of their most popular titles, with millions of players playing the slot each year. Set deep within the Jungle, Big Thunder uses 5 reels and 20 pay-lines and offers treasure rewards for those lucky players, alongside up to 30 free spins, in the lucrative bonus round!

Players can spin from as little as €0.30 a spin, right the way up to €3,000 – and yes, you read correctly… the maximum spin is a whopping €3,000!

The game itself is well designed, with a luscious backdrop of a Jungle, with the low-paying symbols made up of traditional playing card symbols, including 10, J (Jack), Q (Queen), K (King), and A (Ace), and the high-paying ones including game specific symbols, such as a Bingo Drum, a Waterfall, a Mask, a Shield, and a Snake.

Game Features

First off, you’ll need to take a moment to look out for the scatter symbol – this is a Big Thunder logo, and if you manage to land three, four, or five of these on any spin (the position of the scatter symbols doesn’t matter), you’ll win 15 free spins. You’ll also win 2, 20, or 50X your stake for landing them (the more you land, the higher the payout.)

Now, during the free spins round, you’ll be taken to a new set of reels. On these reels, all the traditional playing card symbols, including 10, J (Jack), Q (Queen), K (King), and A (Ace), are removed, leaving you with just the high-paying ones!

Plus, that’s not all; the pay-table increases and the symbols on the reels pay more, with 5 of a kind of the Gorilla Wild paying a whopping 70X your total stake!

There’s also the 6th reel during the feature, which contains 3X and 5X multipliers. If they land on a winning spin, they’ll multiply your win by their value, and if you land two, they’ll multiply against one another!

It’s possible to re-trigger the bonus round by simply landing another three, four, or five scatter symbols anywhere in view; and do so, and you’ll win another 15 free spins!

Big Thunder slot is available to enjoy on mobile phones and smart tablet devices, and you’ll be able to play the game without downloading anything – it’s all browser base! Simply open up Big Thunder from your chosen online casino, and begin spinning – it’s simple!
