Big Thunder is an unusual game because although on first appearance it looks just like a standard set of five reels, if you peer more closely you’ll see an extra reel on the side, making six.

You can still win prizes in the normal way, by matching up symbols on the main reels but there’s a whole host of extras which could help you get bigger payouts. (But more of that below…)

The graphics from Ainsworth are top notch and will make players feel as if they really are hidden in the centre of a tropical jungle. Keep your eyes open when you win and you’ll find short bursts of animation such as the gorilla beating its chest; the developer has taken its time to add the finer details which really adds to the overall experience.

The Mysterious Number 6

The Big Thunder is the scatter symbol and if you land three or more anywhere on the reels you’ll unlock the Bonus Reel feature.

This adds the 6th reel to the game and with it, extra symbols become active too such as the x3 and x5 multipliers. While the bonus reel is in play, all wins pay any and the multipliers apply to the whole of the reels.

A different paytable is active for the Bonus Reel feature with bigger prizes and a top win for matching all six symbols too. You’ll still have the benefit of both a wild and a scatter and you can retrigger 5 free spins if you land three or more Big Thunder symbols.

Whichever set of reels you play, you won’t find the prizes coming thick and fast as this is a slot with medium volatility and a RTP rate of just 94.38%, putting it into one of the lower categories.

Big Bonuses

As well as the extra reel, Big Thunder offers more chances to scoop a big payout, but you’ll have to be very lucky to win.

On the main screen you’ll see four tracker windows at the top, showing the current values for the four different bonus payouts.

Mini, Minor, Maxi and Major: there’s a range of different bonus jackpots which could be up for grabs. However, you won’t find it easy to win because unlike other games these payouts aren’t triggered randomly. To be a winner you’ll need to spin a very specific combination on the reels.

You’ll need five of a kind to win most of the prizes and if you use the wild as a substitute to achieve this, you’ll be downgraded to a lower bonus payout. To get the very largest prize, the Major Bonus, you’ll have to land five identical symbols on the reels plus the King Strike symbol on the extra reel, too.

Join in the Jungle Japes

Before you start to play on the reels, you might want to try out Big Thunder first as there’s lots of unique features to familiarise yourself with.

The demo mode allows you to try out the slot, and discover for yourself just how the unique 6th reel works before you risk your own cash. In the demo mode you’ll still be able to enjoy all of the functions but you won’t be eligible to win a real money prize.

Nevertheless, this is a useful tool for both beginners and those who haven’t played an Ainsworth title before, allowing you to try out your strategies first and make sure you’re certain before playing for real.

Beating the Drum

Big Thunder from Ainsworth is an online video slot which has everything from gorillas and waterfalls to ancient drums and masks to create an authentic jungle atmosphere. The game is rammed full of features so you’ll never get bored playing this title! Due to the complexity and the relatively high volatility it’s a title best suited to intermediate or advanced players only.
