Gorilla Mayhem — review

Pay-anywhere grid and Wild Gorilla

The maths engine underneath Gorilla Mayhem is Pragmatic's familiar pay-anywhere framework: any eight or more identical icons scattered across the 6×5 grid resolve as a win, regardless of position. Structurally this puts the title in the same category as Sweet Bonanza and Candy Blitz — nothing about line adjacency matters. Once a cluster pays out, the contributing icons disappear and fresh symbols tumble in from above, potentially firing another chain. What sets this release apart in base play is the Wild Gorilla: a bespoke wild that arrives mid-cascade, thumps its chest and converts three to six surrounding cells into additional wilds. Add a four- or five-tumble sequence with one of these interventions and a modest opening cluster can compound into a 50-200x hit surprisingly quickly.

Hold & Win bonus with 8-spin reset

Six coin scatters on-screen triggers Hold & Win — the headline feature. The round opens with 3 respins, and from that point onwards only cash symbols or blank cells populate the reels. Every new money icon locks into position and refreshes the remaining counter back to 8. Sequences of five to ten-plus fresh coins per feature are the engine that drives the 5,000x ceiling. Individual coin values run from 1x through 500x the stake; the "Collector" variant totals every coin already showing on the grid, whilst a "Payer" doubles-to-tenfold multiplies its own denomination. Fill all 30 positions and a 2,000x grand prize is awarded on top.

Bonus Buy and Ante Bet

In jurisdictions where it's allowed, Bonus Buy is priced at 100x the stake and drops you straight into Hold & Win. Under the Buy path, theoretical RTP nudges up to 96.71%. The alternative — Ante Bet — inflates the wager by 25% and roughly doubles the natural bonus-trigger rate; RTP stays anchored at 96.50%, and for grinders wanting more bonus rounds without the all-or-nothing Buy commitment it's often the more sensible compromise. Both are switched off automatically whilst any welcome-bonus wagering is running.

Bankroll and betting

Stakes range from £0.20 up to £100 a spin. Multiplied out against the 5,000x cap, that spans £1,000 to £500,000 in raw theoretical maximums — although reaching the ceiling requires a properly extended Hold & Win chain and remains a genuine rarity. A workable bankroll sits around 200-300 base spins per session (£40-£60 when playing at £0.20). Natural bonus triggers land roughly once every 200 spins; that halves to about 1-in-100 with Ante Bet engaged. Apply a 40% loss-stop discipline.

How Gorilla Mayhem compares

Looking at Pragmatic Play's own line-up, this game slots into the Hold & Win family next to Wild Wild Riches, Big Bass Hold & Spinner and John Hunter Tundra's Treasure. Its calling card is the 8-round reset window — Pragmatic's more conventional Hold & Win releases use a 3-round refresh — and it appeared across around half a dozen 2024 titles as part of the studio's mechanic refresh; the practical outcome is bonus sequences that run noticeably longer whilst coins keep dropping. Set beside non-Pragmatic Hold & Win competitors such as Wazdan's 9 Coins or Playson's Solar Queen, this release wins on ceiling (5,000x versus their 2,000-3,000x) but concedes a little on trigger frequency. The Wild Gorilla base feature is arguably closer in spirit to Sweet Bonanza's Multiplier bombs than to any classic wild.

Mobile and studio quality

Pragmatic's technical build is polished — portrait-optimised layout, 60fps tumble sequences, and Wild Gorilla's chest-thumping animation renders cleanly even on entry-level Android handsets. Download footprint sits around 8 MB. During Hold & Win, both coin faces and the reset counter remain legible without needing to pinch-zoom. The soundtrack can be muted without any timing consequences. Auto-play blocks come in 10/25/50/75/100 increments, and we enable the operator-side loss and single-win limit toggles by default, in keeping with UK responsible-gambling conventions. Pragmatic ships this title with three certified RTP variants — 96.50%, 95.53% and 94.03% — and we run the top-tier 96.50% configuration; worth double-checking via the in-game info panel when you first load a session.
