Big Thunder is an extravagant, flashy game brought to your screens by game provider, Ainsworth. Think King Kong combined with Tarzan, and throw in a few extra jungle clichés, and you have the basic concept for this explosive game. Whilst the game itself might be an amalgamation of existing classics, that’s not to say it doesn’t have plenty of original perks to it, which will have you hooked. You can try this game, alongside hundreds of others, for free on your desktop, mobile and tablet devices at Slots Temple.

King of the Jungle

A mighty silverback gorilla is the king of the jungle in this particular Ainsworth slot. Similar in many ways to Peter Jackson's King Kong, it's clear to see which similarities the developers have drawn from the famous tale when creating their main man, 'Big Thunder'. Ready your nerves as you prepare to spin, serenaded by a whirl of reels and a booming crash of thunder when landing certain slots - this game exudes excitement from the very second you begin to play.

As our protagonist is the biggest beast in the jungle, it seems only fitting that the payout opportunities reflect this. The game consists of 5 reels and 30 paylines, and there are up to four jackpots to win, alongside the normal gameplay. 

The eighth wonder of the world

The jackpots you can win increase gradually in size with each one. There’s the mini jackpot, which lives up to its name and offers the smallest payout. Then there’s the minor jackpot, which offers a modest, yet slightly bigger, payout. Following this is the ‘maxi’ jackpot. Finally, leading the pack, we find the ‘major’ jackpot. These jackpots will increase as you increase your bet, so it follows that the bigger your bet, the better the chances of winning big.

To put the potential payout into perspective, if you fancy yourself as a high roller, if you stake the maximum bet of £3000 and manage to win the major jackpot, you’ll reel in an absolutely astounding £1,000,000 payout. That’s one million smackers! That’s got to be one of the biggest potential payouts we’ve ever seen on an in-game jackpot!

So, how do I get my hands on the cash?

The ordinary gameplay, before you take the jackpots into account, offers modest payouts. The bonus reel feature games can be triggered by collecting three or more ‘Big Thunder’ scatter symbols. This is an intriguing game round, during which a special 6th reel is introduced, on which 3x and 5x multipliers will randomly appear, to boost your winnings.

During this round, 5 additional games can be granted by finding another three or more scatter symbols. To be in with a chance of winning one of the jackpots, you have to jump through a few hoops - for example, for the major bonus, you must find five higher paying symbols along with the crown on the 6th reel for the 10,000x line bet prize. Whilst this is tricky, it’ll be worth it when the cash starts rolling in!

And playing this game or one of many others on our site is the best way to test which titles you want to experience for real.
