The only thing we can think of that's scarier than thunder hitting you is a gorilla charging at you. So what happens when you combine the 2? Well, as you'll see in <strong>Big Thunder Quadshot</strong>, the result is big combos and even big payouts. Although it's set in a forest, this bombastic game isn't the tranquil experience you'll encounter in other slots, but rather takes you on a wild ride once you've picked a stake ranging from $1.25 to $25 and started spinning the game's 5 reels. The bonus features are fairly straightforward, but just as rewarding as those out of any other slot. The game's primary bonus is the Bonus Reel, which is a take on free spins that's triggered by landing 3, 4 or 5 scatters on the reels. Once you trigger the feature, you'll get a 5, 20 or 100 times return of your stake, along with 15 free spins. The free spins will occur on a different grid with only high-value symbols, and the combos will often be accompanied by 3x and 5x multipliers. Landing the scatter again during this feature will return 200 times your stake, while landing 3 of them during a single spin will give you 5 more free spins. Aside from this captivating feature, the game has 4 different jackpots you can get during any spin if you can manage to land 5 of the same symbol on a reel. Regardless of which of the jackpots you land, we're sure you'll leave this slot with a much better opinion on gorilla than you've previously had.
