Gorilla Mayhem Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 1,024 ways to win

Stakes Range: 20p to £100 per spin

RTP: 96.5%

Max Win: 5,000 x bet per spin

The Gorilla Mayhem slot is played with 5 reels, 4 rows and 1,024 ways to win. Landing 3 or more matching symbols, from left to right on adjacent reels will result in a winning combination. The only exception is the gorilla symbol whereby only 2 are required to land.

Playable from 20p to £100 per spin, there are plus and minus buttons on either side of the Spin button. This allows you to change your bet and the coin value. In the System Settings section, there is a Quick Spin mode. You will also see the Autoplay button under the Spin button where you can choose up to 1,000 autospins as well as Turbo Spin. Both these functions are not available in the UK.

The Gorilla Mayhem RTP is 96.5% which is in line with other Pragmatic Play slots and a lot higher than the standard 96% rate for online slots. The provider also offers 95.5% and 94.5% RTP versions so check at the casino you play at which version you’re playing. The best slot sites in the UK will have the 96.5% rate.

Highly volatile (5/5), you’ll get a win less often on average but the chance of big wins in a short time spin is higher. The maximum win per spin is 5,000 x your total bet. The bigger payouts will derive from the Golden Gorilla symbols which come with multipliers if you land 2 or more.

Theme – head to the jungle for chaos

Theme: Gorilla

High Value Symbol: Gorilla

Compatibility: Mobile, Tablet, Desktop


With a gorilla theme, the Gorilla Mayhem slot takes you into the heart of the jungle. Based on mountain gorillas, the setting is Africa where the foliage is dense. The soundtrack is excellent and features African drum music which adds to the intensity. Visually, it looks a lot like NetEnt’s Jungle Spirit: Call of the Wild.

With the reels surrounded by vines, symbols include low value A, K, Q, J and 10 royals. The 5 high value symbols include snakes, parrots, hippos, crocodiles, leopards and, of course, gorillas. The gorilla is the best paying symbol with 2, 3, 4 or 5 in combination awarding 0.5, 1.5, 3 or 4 x your total bet.

Gorilla Mayhem comes with 2 wild symbols. You have a standard wild symbol which appears on all reels bar reel 1. It substitutes for all symbols mentioned above. There is also a Golden Gorilla wild (more on this below).

Gorilla Mayhem Mobile


With Pragmatic Play created all their slot games with HTML5 technology, Gorilla Mayhem is optimised for play on desktop, mobile and tablet devices. This includes smartphones operating with iOS, Android and Windows.

Gorilla Mayhem Bonus Features

The Gorilla Mayhem slot has 4 bonus features. You have the Golden Gorilla Multiplier which gives you a multiplier up to 3x. Then there’s the free spins where gorilla and golden gorilla symbols are collected. This will lead to reaching a higher level which ensures the Golden Gorilla multiplier is higher.

Golden Gorilla Multiplier feature

The Golden Gorilla wild symbol appears in the base game on reels 2, 3, 4 and 5. Substituting for all paying symbols, 1 Golden Gorilla represents a 1x multiplier. When 2 or more Golden Gorillas appear, the Golden Gorilla Multiplier feature is triggered:

2 Golden Gorillas 2x multiplier
3 Golden Gorillas 3x multiplier

Free Spins feature


The Free Spins feature is activated when 3 or more crystal scatters appear anywhere on the reels. 3, 4 or 5 scatters will award 10, 15 or 20 free spins respectively.

The free spins benefits from a Progressive feature. All gorilla and golden gorilla symbols are collected. When you collect 40, the level increases and the Golden Gorilla multiplier rises in value:

Level Gorillas Collected Golden Gorilla Multipliers
1 40 1x, 2x or 3x
2 80 (in total) 2x or 3x
3 120 (in total) 3x

Each level you reach also awards 3 additional free spins. If you reach level 3, landing 2, 3, 4 or 5 scatters will give you 5, 10, 15 or 20 extra free spins. You can win unlimited extra free spins.

Outside of the UK, there is a Buy Free Spins feature. Gain direct entry to the Free Spins feature for 80 x your total bet. You will randomly land 3, 4 or 5 crystal scatters (for 10, 15 or 20 free spins).

Gorilla Mayhem Review Summary – Golden Gorillas key to decent wins

Theme & Symbols

Bonus Features

RTP (96.5%)

Max Win (5,000 x)


The Gorilla Mayhem slot may look like Jungle Spirit: Call of the Wild but it has many similarities to another NetEnt slot, Gorilla Kingdom. With the same number of reels and paylines, the diamond scatter is very similar to the crystal in Gorilla Mayhem. The gameplay though is different.

The biggest wins will come from the Golden Gorilla Wilds which come with random multipliers up to 3x. In the free spins, collecting gorillas will increase your level and only allow the higher value multipliers to land on the reels.  The Progressive feature is similar to that in Gems Bonanza (by Pragmatic Play) where collecting symbols increases the multiplier up to 10x.

Overall, Gorilla Mayhem is an adequate slot where Golden Gorillas are needed to achieve a decent payout. Will be prove as popular as Pragmatic Play favourites such as Sweet Bonanza or Barn Festival? I think not.

I recommend you head to the jungle with NetEnt’s Silverback Gold. With a similar look, you collect tokens in the Free Spins feature to upgrade Silverback symbols to Golden Silverbacks. This can lead to 45,126 x bet max wins.

  • 5,000 x bet max wins
  • Unlimited free spins + Golden Gorilla multipliers
  • Graphically very similar to other slots
