Features & Overview

Big Thunder is a nice simple slot game and the bonus bets feature is great, but it follows in the footsteps of many of Ainsworth’s games with the lack of presentation. There aren’t a lot of sounds in the game and the graphics look a bit cookie cutter if you’ve played other Ainsworth poker machines.

There is a Bonus Reel feature in Big Thunder which is triggered when three Big Thunder symbols appear anywhere on the board. During this feature, there is an extra reel with x3 and x5 multiplier symbols and the Big Thunder symbol. When you land one of these symbols on the bonus reel with a win, your win will be multiplied. This feature is active for 15 spins no matter how many symbols you land to trigger it, although you can win an additional 5 spins for landing 3 Big Thunder symbols during the feature.

The King Strike bonus is sort of an addition to the standard payline wins. These wins only occur when you get a payline win with no substitute symbols and a King Strike symbol appears on the bonus reel to the right. Only payline wins with five of a kind will trigger the King Strike bonus, and the payout will depend on the symbol. You can win €5, €10, €25 or €100.

The Big Thunder video slot title is a well-designed 3D slot from Ainsworth King Strike series. If you are looking for action-packed gameplay with flexible betting options, then this slot may be the answer as it rolls in free spins with multipliers as well as retriggers, stacked wilds, large scatter multipliers, and 4 jackpots that can be triggered at any time thanks to a 6th bonus reel.

Theme and Story Line

The Big Thunder slot title comes from the line of Ainsworth ‘King Strike’ series of slots. The theme is set in the dense jungles somewhere in South East Asia where tigers and gorillas roam amongst Buddhist and Hindi relics in a bid to bring good luck and fortune to the reels.

Graphics, Sounds and Animations

Ainsworth’s slot developers have done an amazing job on this slot’s design. The graphic design work is centred on the jungle backdrop, and symbols of ancient relics and wildlife, which are all in 3D with a crisp finish so they appear clearly on mobile and desktop devices. Regardless of the device, you play this slot on, you will be able to have a shot at the progressive jackpot on a quality designed slot.

The sound effects are also different compared to most Ainsworth games. Usually, this slot developer goes for classic slot sounds and lets the gameplay do all the talking. However, on the Big Thunder online slot game you are treated to tigers and gorillas roaring, the sound of thunder as an animated thunderbolt hits the reels in anticipation of triggering the bonus scatter.
