Big Thunder Slot Machine

Not to be confused with the Thor-themed slot Thunder Cash from its own stable, Ainsworth's Big Thunder King Strike actually features a King Kong-like main character on its five reels. Not just that, but the lush background is packed with jungle symbols and forestation.

If you're familiar with Ainsworth's King Strike jackpot games (Hotter Than Hot is a particular favourite of ours) you'll know all about the four progressive jackpots features here. Even at the low limit stakes players have the chance to bag one of four massive prizes.

Play 30 Paylines For Real Cash Jungle Fun

Let's look at the base game first. You can spin over 30 fixed lines on each spin and choose coins from 0.01. However, with a top max bet of 3,000.00 (at 100.00 a spin) there's plenty of fun if you play for real money.

The base game symbols include 9-through-Ace icons, with 3OAK of the letters and numbers paying 5 coins. The waterfall, drum, mask, tribal shield, and boa constrictor are betting, paying about 8 coins.

The Gorilla Wild substitutes for all regular symbols. Look out too for the BIG THUNDER Scatter symbol which pays anywhere. It pays 60 coins for three of a kind. Five Wilds on a payline will dish out 1500 coins, or 50x your stake.

Land Three Scatters For BIG WIN Bonuses & Spins

If you land three or more BIG THUNDER Scatter symbols anywhere, you'll trigger the BONUS REEL FEATURE free spins.

15 spins are yours to play, but the bonus reel appears alongside the regular set with two new bonus symbols on it - 2x and 5x multipliers. Scatters can also appear on this "sixth reel" and three or more Scattered BIG THUNDER icons re-triggers the free spins round.

It's a pretty decent bonus game to hit, and you can get some big wins this way. We managed to re-trigger our round on our first or second attempt for a total cash-out of just under 95x our total stake. Note that the Gorilla Wild now comes into play as well, with just two-of-a-kind dishing out 5 coins.

Win One Of Four Progressive Jackpots

When you play for real money, you'll notice the four King Crowns at the top of the reels: Major, Maxi, Minor and Mini. These are progressive jackpots and the totals increase depending on your total bet. For example, the low limit Mini has a seed of 5.00 on a total bet of 0.30. The Major prize is for the high roller gamblers, with a 1,000,000.00 prize up for grabs.

To hit any of these you'll need to line up 5OAK on the reels PLUS a King's Strike symbol on the 6th reel (the 'Bonus Bet' reel). Wilds cannot help you complete a winning combination for the major and Maxi bonus, and with lots of Wilds "in the way" this is harder than it sounds. However, if you make a 5OAK payline that includes a Wild you'll revert to the next jackpot down the tiers.

Play The Free Big Thunder: King Strike Slot Today

This is definitely an online slot for the big-spending online casino players. When you whack up those coin bets you can enjoy even a 50,000.00 jackpot for the Mini (as long as you line up five 9, 10, J, Q, K or Ace symbols with a Wild).

Big Thunder has some serious high volatility, for sure, and if you already enjoy Hotter Than Hot you'll get a kick out of this. Try that Ainsworth game at your favourite online slot machines site today and see if you can crack the Major.
