Big Thunder Slots

Come face to face with one of the biggest beasts in the jungle and you could be in for some big wins in this new slot machine by Ainsworth software.

Big Thunder is based on a legendary silverback gorilla who resides in the tropical jungles of this online video slot, acting as wild symbol to help complete potential line wins.

The 5-reel game 30 paylines in total, with some fairly low variance when it comes to the frequency of winning spins. And just because the wins come more often than not, it doesn't mean that the game won't pay out some decent prizes, because there is a special bonus reel that presents the chance to win one of four jackpots.

Come Face to Face Big Thunder

It's not every day that we get to come face to face with one of nature's most powerful specimens but spinners of this slot machine will have the chance to spot a true beast – the gorilla known as Big Thunder. The game takes punters deep in to the thicket of a tropical rainforest, where the reels are surrounded by an overgrowth of primordial leaves and constricting vines. Upon the reels, players will find a number of artefacts from the rarely explored habitat; there are tribal drums and masks, warriors shields, huge python snakes and, of course, the star of the show himself – the imperious silverback gorilla.

It has to be said that this video slot by Ainsworth game studio is far from being the most spectacularly designed game in the business, with its two dimensional illustrations and somewhat generic use of playing card symbols – 9, 10, J, Q, K and A. Nevertheless, the slot machine does have a classic feel to it, meaning that it might appeal to fans of classic video slot machines like Wolf Run and Amazon Queen.

Abundant Wins

Big Thunder can be played with 30 paylines or, if punters wish to limit their outgoings, the video slot can be set to spin with just 1, 2, 3, 5, 10, 15, 20, and 25 paylines. Of course, the low volatility slot machine is going to be much more exciting to play when all possible ways to win are active over the reels. When the maximum number of paylines are activated, players will be able to place a maximum bet of 3,000.00 credits with 100.00 on each line. That is perfect for high rollers but casual players need not feel overwhelmed by this since the minimum bet with all lines active is 0.30 credits.

Considering that this low variance slot machine tends to payout on a regular basis, spinners should not expect to find any huge base game wins in Big Thunder. In fact, the biggest line bet multiplier on the board is set at 200x and that is awarded whenever five waterfall or drum icons appear on an active paylines.

That is far from being the most attractive of line bet jackpots in the business but, then again, this slot machine does have a couple of special bonus wins hidden in amongst its jungle environment.

Beast of a Bonus

First of all, players can boost their wins substantially by finding five “Big Thunder” scatter symbols in any position over the reels. This will award a 50x total bet multiplier prize which – if all paylines are active – will provide a prize return that is significantly more lucrative than the top line bet prize. Not only that, but three or more scatters on the reels will trigger a round of 15 free spins, during which the paytable offers bigger prizes such as a 200x total bet prize for five scatters and a 2,000x line bet prize when five wilds align. The free spins feature also offers multipliers worth x5 and x3, making it every bit likely that punters will boost their balances in the right direction.

The biggest bonus wins in Big Thunder are awarded courtesy of the special bonus reel at the right hand side of the game screen. This special 6th reel will either show a blank or a golden crown – if the crown appears along with the right combination of icons on the reels, players could be in store for a huge 10,000x line bet prize. Here is how it works:

  • Mini bonus: find five 9, 10, J, Q, K or A symbols with at least one wild to win a 500x line bet prize.
  • Minor bonus: find five mask, drum, snake, waterfall or shield icons with at least one wild to win a 1,000x line bet prize.
  • Maxi bonus: find five 9, 10, J, Q, K or A symbols to win a 2,500x line bet prize.
  • Major bonus: find five mask, drum, snake, waterfall or shield icons to win a 10,000x line bet prize.

Worth a Spin?

With some slightly outdated graphics and low volatility gameplay, this slot machine might not instantly appeal to players who are after spectacular visual frills and big winning thrills.

However, Big Thunder has plenty of merit thanks to its interesting and unique bonus gameplay features, with some lucky spinners in with a chance to win a 10,000x jackpot.
