Gorilla Kingdom uses Free Spins to turn a totem display into a long-term transformation goal. Scatters award ten to twenty spins, while a Gorilla symbol can randomly leave behind a mask that fills one slot in an animal panel. Complete all six positions in any panel and that animal turns into Gorilla symbols; fill all 24 and only Gorilla symbols appear on the reels. The 5×4, 1,024-way base game leads into a feature where progress is visible but the completion rate is not specified.

A 1,024-way base game leads into the Totem Stone
The game uses five reels by four rows, with 1,024 ways listed. Three or more Scatters anywhere award between ten and twenty Free Spins, but the source does not give a Scatter-count table assigning each award. During Free Spins, the Symbol Transform feature can convert totem animal symbols into Gorilla symbols. A Gorilla may randomly turn into a Gorilla mask, filling a slot on the Totem Stone while leaving a Gorilla symbol on the reels. The animals represented are Leopard, Hornbill, Okapi and Pangolin.
Each animal panel has six slots. When all six are filled with Gorilla masks, that animal turns into Gorilla symbols. The complete Totem Stone has 24 positions; when all are filled, only Gorilla symbols appear on the reels. This produces two levels of progress: completing one animal panel changes that animal into Gorilla symbols, while filling every panel changes the reel population more broadly. The source does not state whether completed panels remain filled or how the resulting Gorilla symbols affect the ways count beyond being symbols on the reels, so the review does not add a persistence or payout rule.
Retriggers add time, but panel completion is uncertain
Three to five Scatters appearing in Free Spins award ten to twenty Extra Free Spins according to the source description, matching the broad range given for entry. Exact amounts by Scatter count are not itemised. The main Transform feature is described as happening during Free Spins; no separate reset or completion threshold is stated for the Totem Stone beyond six masks per animal and 24 overall. As a result, the feature has a clear completion condition but an unspecified rate of mask generation.
The broader source description includes B2B promotional copy about market appeal and simplicity; that is not evidence about how the game plays and is excluded from the review. The mechanics themselves support a focused assessment: repeated transformations build panel progress, and completed panels change which symbol appears on the reels. What cannot be assessed is how many Free Spins usually produce a completed panel, whether all four panels advance at the same rate, or how the feature’s wins are calculated after a transformation. Those are material omissions for estimating the pace of the bonus.
Reference values
The official record lists RTP 96.03%, volatility 8.3 and maximum payout 1,700× bet for this title. Operator settings may vary; no maximum-win probability is stated. The 24-slot completion goal and ten-to-twenty Free Spins range are documented, but mask probabilities and exact Scatter awards are not. The full-totem endpoint describes an all-Gorilla reel state, not a guaranteed payout amount.
Strengths and weak points
Strengths
The Totem Stone has clear intermediate and full-completion milestones: six masks transform one animal panel, and 24 complete the entire board. Each step changes reel symbols rather than only a counter.
Weaknesses
Mask frequency, exact Scatter awards and panel payout effects are missing. Without those details, the progress board is visible but its likely pace and value remain difficult to judge.
Our Editor’s View
Gorilla Kingdom gives its bonus a visible destination: masks fill one of four six-slot animal panels, and a completed panel changes that animal into Gorilla symbols. Filling all 24 positions marks a larger transformation across the reels. This gradual board goal is more distinctive than a standard retrigger-only feature, and the Scatter retriggers can provide additional time to pursue it. The weakness is that neither mask frequency nor the exact Scatter award mapping is included, while the source leaves payout consequences of completed panels undescribed. Players who like tracking a collection board alongside ways wins may find the structure satisfying; those who want to know how often a panel completes or what exact value it adds need fuller rules. The catalog maximum does not substitute for those missing mechanics. Related review: 5 Lions Reborn’s animal-themed bonus mechanics.
