Big Thunder Slot is a medium volatility game with a 5x3 grid structure and a bet stake range of 0.01-100. The game offers an autoplay option in the form of auto games, which can be selected at rates of 10-100 auto games at a time. An interesting feature of this game is that it gives players the ability to adjust the number of pay lines they bet on in a range of 1-30. This means that players can increase or decrease the number of possible pay lines they will get paid out on, as opposed to more conventional slot games that only allow a fixed number of pay lines. While we really liked having this option, we kinda wish they went a step further to allow players to select the number of coins per line, or even the value of coins in the game. Another big plus, however, is the fact that Big Thunder Slot tracks your game history, allowing repeat players to keep track of their winnings as well as their losses. We think this is really great especially because it promotes playing responsibly which is something, we are strongly in favour of.
Big Thunder Slot has a return to player of 94.38%. This essentially means that the game will reward players with 94.38% of what is staked on it globally. While this may not seem like a terrible rate, it is a little lower than the industry standard which is around 96%. This is the one feature of slot games were bigger is undoubtedly always better. But even if it isn’t the most generous game, in this case, the gap wasn’t nearly big enough to discourage us from playing.
Big Thunder is a simple 2D slot with a crisp and clear interface but overall pretty standard visuals. While its far from the flashiest slot around, the jungle theme is rife in this game, and the sudden and abrupt sound effects keep in with this theme very well. Jungle drums, gorilla roars and cracking thunder will keep you on your toes as you delve deep into the jungle. Aztec masks, jungle drums, snakes and the big mighty gorilla that represents the games wild are among the mysterious symbols that may lead to your Amazonian treasure!
We missed having arrow buttons to press when adjusting the bet value of our bets, as the scrolling function was a little sticky. But overall, we found the interface to be equally clear and responsive on desktop and mobile.
We can’t say that we were overly impressed with the overall design of the game, but it does have a certain character to it. Ainsworth kept it straightforward here and gave players with a flair for the rainforest a quality gaming experience that puts them right in the beating heart of the jungle.
When it comes to Big Thunder slot machine, the proof is really in the pudding. And by pudding, we mean bonus features! Big Thunder has a great variety of bonus features including a free spin feature that is fairly easy to trigger. Big Thunder slot also offers players the chance to win from a quartet of Big Thunder progressive jackpots which can be mini, minor, maxi or major jackpot. While the wild gorilla only appears on reel 3, 4 and 5 only.
A Big Thunder logo, representing the scatter symbol, will payout in any position it lands on, and can give you back x2, x20 or x50 times your stake if you land 3, 4 or 5 of them anywhere on the reels. This will also trigger the bonus reel feature, awarding 15 free spins, but more on that in the next section. Even though the wild gorilla doesn’t pay out it does substitute for all symbols except the scatter, multiplier and king strike, making winning combinations that much easier to come by!
Landing 3 or more scatters symbols will trigger the Big Thunder slot glorious Bonus Reel Feature and the sweet 15 free spins that come with it. While the feature is active, a bonus reel will appear offering 2 new bonus symbols, ‘x3’ and ‘x5’, as well as the scatter. The wild gorilla will substitute for all symbols except for ‘x3’ and ‘x5’. As we’re sure you guessed, landing either of these symbols anywhere on the bonus reel will see your winnings for that game either TRIPLED or MULTIPLIED BY 5! We think that’s pretty sweet.
During every bonus reel round, an extra 5 bonus reel rounds are triggered whenever 3 or more scatters appear anywhere on the reels. While this feature is active the ‘feature paytable’ is applied, so be sure to check that out so you’ll know exactly what to expect. Incidentally, bet lines are paid at the same stake that triggered the Bonus Reel Feature.
Big Thunder Slots offers players the chance of winning 4 exciting bonuses during their King Strike Bonus rounds. The Major Bonus is rewarded when a 5 of a kind Waterfall, Drum, Shield, Snake or Mask win line occurs with no substitutes appearing, and a King Strike symbol appears on reel 6. The Maxi Bonus is given out when a 5 of a kind Ace, King, Queen, Jack, Ten or Nine win occurs with no substitutes, while a King Strike symbol appears on reel 6. The Big Thunder slot Minor Bonus is triggered when a 5 of a kind Waterfall, Drum, Shield, Snake or Mask win occurs, with at least one substitute appearing in the winning pay line, as well as a King Strike symbol appearing on reel 6. The Mini Bonus is awarded to players when a 5 of a kind Ace, King, Queen, Jack, Ten or Nine winning pay line occurs, with at least one substitute appearing in the winning combination line, in addition to a King Strike symbol appearing on reel 6. It’s also worth noting that bonuses cannot be triggered during the bonus reel feature. Overall, we’d say that even though they may be hard to come by, they are pretty favourable Bonus rounds.
We can say we had a pretty decent time trying our luck in the jungle on Big Thunder. The game is solidly designed and offers a straightforward user-friendly experience. While the audio and visuals aren’t the most immersive, we’ve seen, we think this is a quality game from Ainsworth, and we like how its executed. The ability to select the number of pay lines is always nice to have. So is having the option to track game history. But what really puts the game ahead is its bonus features. From bonus reels and free spins to major king strike bonus rounds, this game really makes the player feel like anything is possible, despite its medium volatility.
