First Impression of Big Thunder

Did you know it is possible to try the Big Thunder play without download, at any of the casinos we recommend? Get in the thick of it in just a moment or two, as this game loads faster than many other titles out there!

Big Thunder

The game is inspired by the wildlife in nature’s green cathedral and features a range of elements we associate with rainforest. Animals, colourful flowers, native tribes and drum beats will immerse you in a world completely different from your Ottawa suburbs or Montreal city centre. It is untamed, roaring, primal, and we can’t get enough of it. After all, it does pay up to x10,000 the bet!

Ainsworth added a standard set of controls that allows you to decide how many lines you want to play and how much you are willing to bet. On top of that, there is also the standard spin feature and auto spin mode, as well as some other fine-tuning features.

Gameplay and Features

Big Thunder slots is a world of its own, but even more, a world you’ll want to enter. Before you put on your trekking shoes, check out our bonus features map.

Big Thunder Base Game

In the Big Thunder slot machine, players must face a 5×3 gambling grid. They can choose to play with up to 30 active paylines. To land a win, simply score at least three icons of the same type in adjacent reels on a payline.

The most valuable symbol in the game is the Big Thunder logo, which pays up to x50 the stake. Another symbol you have to pay close attention to is the gorilla, aka the wild symbol. It is a non-paying icon, but it has the power to substitute any other symbol except the scatter.

Kindly note that during the bonus reel feature, the game pays differently, and in some cases, you’ll need only two symbols in adjacent reels. In the bonus game, the gorilla pays up to x2,000 of the bet.

Bonus Reel Feature Bonanza

Gorilla is not the only thing worth your attention in the Big Thunder bonus reel game, so let’s start at the very beginning.

Whenever you get at least three scatter (Big Thunder logo) symbols in view, you trigger the bonus reel feature. A special bonus reel will appear, displaying nothing but x2 and x3 multipliers and the scatter icon.

King Strike Bonus

Certain combos can bring you prizes the size of an elephant:

Graphics and Design

Big Thunder slots graphics will take you where the wild things are. Its incredibly realistic animations and style choices make it very lifelike, and more impressive than enclosures in the Toronto Zoo.

Slithery snakes that caress branches like vines, majestic gorillas, ritual masks, drums and shields, and majestic waterfalls – all of them tell a tale of the Big Thunder that announces the rain season. And with the Big Thunder slot, it is the money that can potentially rain down on you!
