Big Thunder

Players looking for the next online casino to challenge will undoubtedly enjoy Big Thunder. Developed by Ainsworth Game Technology, this video slot has a lot in store for players who want something new and rewarding. It has a number of regular and special features designed to help players get the most out of their money and time. As with a lot of the titles it develops, the company has also added a unique feature to the video slot that gives players the chance to win various bonuses. Since this is an Ainsworth Game Technology developed video slot, players should be able to enjoy it on either their mobile devices or on computers running on Mac, Windows, and even on Linux distros.


Like most of AGT’s video slots, Big Thunder has follows the standard 5-reel, 3-row video slot format with 30 betting lines and an RTP of 94.38%. Additionally, it also has a 6th reel adjacent to the middle row where a King Strike Bonus symbol appears. Bets can be as low as €.01 or as much as €3000 per spin by tweaking slot’s the bet and lines options. In order to win, a player’s spin will need to result at least in the appearance of 3 adjacent symbols on a betting line. These symbols need to be adjacent to each other with the start of their appearance being at the leftmost reel. To help the player win, the video slot has a Gorilla Wild symbol that can substitute for all other symbols except the Big Thunder Scatter symbol. If they do get 3 or more Big Thunder Scatter symbols (regardless of placement in the slot), players can then enjoy the Bonus Reel Feature consisting of 15 free spins. When this feature is activated, the sixth reel (Bonus Bet) will show X3 and X5 multipliers instead of the King Strike Bonus. As a result, winnings during the free spins will be multiplied by 3 or by 5 depending on the multiplier that appears on the sixth reel. As if this feature wasn’t rewarding enough, the video slot also has King Strike Bonuses. Players are awarded Major, Maxi, Minor, and Mini bonuses when a spin (outside of Bonus Reel Feature) result in the appearance of certain winning combinations along with the King Strike Symbol on the sixth reel. Depending on their initial bet, players win as little as €5 to as much as a jaw-dropping €1million with these bonuses.


As you might expect from Ainsworth Game Technology developed games, Big Thunder features great 2D graphics and minimal audio effects. Though the video slots graphics may be in 2D, the company made sure to still keep it enjoyable and entertaining for players with its use of stylized artwork for the symbols, and background. The video slot’s audio is also subdued with the company refraining from putting in background music to help players focus.

It’s important to note that the Ainsworth Game Technology site does not have a free demo of the video slot. Thankfully, the online casinos mentioned earlier have free demos that players can check out first if they’re still not keen on betting real money on this video slot.
