Gorilla Mayhem

Gorilla Mayhem Slot Review

Sunlight falls in hazy shafts through a rainforest canopy, settling on reels framed in woven vine and pink blossom. Gorilla Mayhem looks like an adventure slot, but its personality is entirely backloaded: the base game is polite, small-pay company, and nearly everything the game actually has to offer appears only once a long round has been earned.

Pragmatic Play built this one on a 5×4 grid with 1024 ways to win, medium volatility, and an RTP of 96.50% in its default setting, though operators can run it at 95.50% or 94.50%. Wins top out at a 5,000x cap, with bets from 0.20 to 240 per spin.

If the sun-drenched jungle appeals, Great Rhino and Congo Cash cover similar ground in the studio’s catalogue.

1024 Ways and the Paytable

All symbols pay left to right on adjacent reels from the leftmost reel, and any left-to-right adjacent combination across the 1024 ways counts. There’s no payline map to learn: a Gorilla on reels one, two and three is a win regardless of which row each lands on.

Only the highest win per way is paid, and when you win on multiple ways at once, all of them are added to the total.

The Wild appears only on reels 2, 3, 4 and 5 and substitutes for every symbol except the Scatter. That leaves the first reel without wild help, which matters on a ways game: every winning combination still has to start with a real symbol on reel one.

The premium end of the paytable is a familiar safari cast, and every value below is a multiple of the total bet:

• Gorilla – 0.5x for two, 1.5x for three, 3x for four, 4x for five
• Leopard / Crocodile – 1x, 2x, 3x for three, four, five
• Hippo / Parrot – 0.8x, 1.5x, 2.5x for three, four, five
• Turtle / A – 0.5x, 1x, 1.5x for three, four, five
• K / Q – 0.3x, 0.7x, 1.2x for three, four, five
• J / 10 – 0.2x, 0.5x, 1x for three, four, five

Only the Gorilla pays anything for two of a kind; every other symbol needs three. Even five Gorillas pay just 4x the bet, which tells you where this game keeps its real money: the features.

The base paytable won’t carry a session on its own.

Golden Gorilla Multiplier

Golden Gorilla symbols appear at random in the base game on reels 2, 4 and 5, and they substitute for the Wild. When one lands as part of a winning combination, the number of gorilla heads on the symbol sets the multiplier applied to that win:

• One gorilla head – x1 multiplier
• Two gorilla heads – x2 multiplier
• Three gorilla heads – x3 multiplier

The multiplier applies to all winning combinations formed with the Wild. It doesn’t stack across multiple golden gorillas in one spin, so x3 is the ceiling on any single base game win.

With the paytable maxing out at 4x, a x3 boost on a five-Gorilla line is the base game’s best realistic outcome. Most golden gorilla hits land on far smaller wins, which is why the symbol is a nudge rather than a headline.

Free Spins

The Scatter lands on all reels, and three or more anywhere on screen trigger the Free Spins round: 10, 15 or 20 spins for 3, 4 or 5 Scatters. Special reels are in play for the duration, so the symbol mix differs from the base game.

It’s a progressive round built on collection. Every gorilla symbol, golden or regular, that lands during the feature is collected into a running total, and every 40 heads raises the level:

• Level 1 – the starting level. Golden gorillas hit as x1, x2 or x3 at random
• Level 2 – golden gorillas hit only x2 or x3; reaching this level awards 3 extra free spins
• Level 3 – golden gorillas hit only x3; reaching this level awards 3 extra free spins

Once level 3 is reached, all remaining spins and any retriggers play out at that level: every golden gorilla from then on is a guaranteed x3. The two level-ups also add six free spins between them, extending exactly the part of the round where the multipliers are strongest.

Retriggers need 2, 3, 4 or 5 Scatters during the round, awarding 5, 10, 15 or 20 additional spins respectively. A two-Scatter retrigger is a soft reward, but it feeds the collection: more spins means more gorilla heads, and more heads means a better shot at the next level.

The structure rewards a long round. A quick 10-spin trigger may never clear level 1, while a well-retriggered round sits in guaranteed x3 territory for its back half.

That asymmetry is the whole design: patience, not luck alone, moves the needle.

Buy Free Spins

The Free Spins round can be bought instantly from the base game for 80x the current total bet. On the triggering spin, 3, 4 or 5 Scatters can hit at random, so a purchase doesn’t guarantee the 20-spin tier: you might pay 80x and start with 10.

The RTP when buying is the same 96.50% as the base game, so the purchase doesn’t improve the maths. What it changes is pace: you skip straight to the collection ladder, where the round’s real potential sits, instead of waiting on a natural trigger.

Given that the power sits behind the levels, buying in buys a head start on the collection rather than a finished result.

Our Honest Verdict

Overall Rating: 7.6/10

Playing Gorilla Mayhem is a gentle jungle stroll punctuated by one genuine stampede. The reason to choose it over plainer safari slots is that single escalating round, where the longer you sit in the canopy, the better every win behind it pays.

That ladder is the design’s one great idea, because a retrigger here is worth more than the spins it adds: every extra head pushes the multipliers towards their ceiling. The weakness is what surrounds it. Five Gorillas pay 4x, so a round that fizzles early pays like loose change, and the 5,000x cap keeps the ceiling honest rather than exciting.

It’s a good home for players who like medium volatility and a slow build towards a locked-in multiplier. Anyone chasing five-figure potential or big base-game swings will find this jungle keeps those animals caged. For the patient, there’s a very pleasant clearing here, and the troop does eventually show up.

Gorilla Mayhem FAQs

• What is the RTP of Gorilla Mayhem?

  Gorilla Mayhem runs at 96.50% RTP in its default setting, though operators can choose lower settings of 95.50% or 94.50%. The RTP is the same 96.50% when buying the bonus.
• How do you trigger free spins in Gorilla Mayhem?

  Hit 3 or more Scatter symbols anywhere on screen to trigger the Free Spins round. 3, 4 or 5 Scatters award 10, 15 or 20 free spins respectively. During the round, 2, 3, 4 or 5 Scatters retrigger the feature for 5, 10, 15 or 20 extra spins.
• What do the Golden Gorilla multipliers do?

  Golden Gorilla symbols substitute for the Wild and carry one, two or three gorilla heads, applying a x1, x2 or x3 multiplier to winning combinations they’re part of. In the base game they appear on reels 2, 4 and 5; in free spins their range depends on your current level.
• How does the level system work in the free spins round?

  Every gorilla symbol that lands during free spins is collected. Every 40 heads raises the level: level 1 lets golden gorillas hit x1, x2 or x3 at random, level 2 restricts them to x2 or x3, and level 3 locks them at x3. Reaching levels 2 and 3 each award 3 extra free spins, and everything after level 3 stays at level 3.
• Can you buy the bonus on Gorilla Mayhem?

  Yes. The Free Spins round can be bought for 80x your current total bet. On the triggering spin, 3, 4 or 5 Scatters can hit at random, so the number of spins you start with isn’t guaranteed.
• What is the maximum win on Gorilla Mayhem?

  The maximum win is capped at 5,000x your bet. If a round’s total win reaches that cap, the round ends immediately, the win is awarded and any remaining features are forfeited.
• Is Gorilla Mayhem high volatility?

  No, it’s a medium volatility game. Medium volatility slots pay out steadily, with the range of pays varying from low to very high.
• How many paylines does Gorilla Mayhem have?
