Gorilla Slot Review: Stacked Symbols and Extra Wilds

Gorilla™ places its defining change inside the free-game sequence: before each Free Game, an extra Wild is added across reels two through five. The bonus begins when three, four or five African Continent Scatters appear anywhere, awarding ten Free Games. That repeated Wild addition gives each free spin a modified setup, while a later set of three Scatters can add five more games only once. The result is a straightforward line game with a feature that alters symbol availability turn by turn, rather than simply applying a fixed multiplier to every bonus win.

Up to fifty lines and stacked Gorilla symbols

The base game uses five reels and up to 50 win lines. Matching symbols must form a connected sequence from the leftmost reel, with five matching symbols stated as the target; they cannot have other symbols interrupting the sequence. The Totem Mask is Wild and substitutes for all symbols except Scatters, while Gorilla symbols can land stacked. A stack makes the central animal symbol occupy multiple positions, but it does not itself guarantee a line: the matching sequence still has to connect across the reels.

The African Continent symbol is the Scatter. Three, four or five can trigger the Free Games feature from anywhere on the reels, so the trigger is position-independent. The award is ten games for each of those counts in the described rule; the page does not indicate different initial totals for three, four or five. The title’s animal theme is directly reflected in its symbols and feature, supporting the existing Animals genre without requiring a broader fantasy classification.

Wilds are added before each Free Game

Before every Free Game, an extra Wild symbol is added to reels two, three, four and five. This changes the symbol setup repeatedly during the feature: the player is not relying only on Wilds that happen to land naturally, because the rules add one to each of four reels before each bonus spin. The description does not specify whether these added Wilds are single positions, stacked symbols, or how they interact with a Wild that already appears. It is safest to describe the addition exactly as stated and not infer a guaranteed full-reel Wild or guaranteed win.

Three further Scatter symbols during Free Games award five additional games. This is a defined retrigger, but it has a boundary: after that award, three Scatters in the Free Games pay their win value and do not trigger any more Free Games. The distinction prevents an assumed endless loop. The initial bonus can therefore extend by the stated five-game award, but the same trigger condition does not keep extending play indefinitely. The rules gives no maximum cumulative spin total beyond this rule, and does not explain whether four or five Scatters during the feature change the extra-game award.

The repeated Wild addition and Scatter retrigger affect different things. Added Wilds change the symbols available before each spin; Scatters can renew the number of remaining games once, then become payout symbols rather than another retrigger. That provides a useful feature rhythm while retaining uncertainty about how often the added Wilds complete winning lines. A more populated Wild setup improves substitution opportunities in principle, but no odds or win guarantee are supplied.

Settings and scope

The online game description lists five reels, up to 50 lines and volatility 4. It does not state an RTP, maximum win, release date, reel-row count or exact selected line configuration. “Up to 50” is important: the public description does not say that all lines are fixed or always active. Without an exact operator paytable, the listed volatility category cannot determine how often wins occur, and the Wild addition does not quantify the feature’s expected value. Those values remain outside the documented rules rather than being inferred from the game’s animal symbols or bonus name.

Strengths and weak points

Strengths

Adding a Wild before every Free Game gives the bonus a clear repeated change, while the one-time five-game Scatter retrigger has an explicit stopping boundary.

Weaknesses

The rules do not define the exact active line configuration or how added Wilds occupy positions, and offer no RTP or maximum-win figure for comparison.

Our Editor’s View

Gorilla’s bonus stands out through a repeated setup change: one extra Wild is added across four reels before every Free Game. That gives the feature a concrete identity and a direct relationship to line completion, while the Scatter rule supplies a bounded extension—three further Scatters add five games, and later Scatters no longer retrigger. The base game remains familiar enough to read, with left-starting matches, a substituting Totem Mask and stacked Gorilla symbols. Its main uncertainty is quantitative rather than structural: the exact active line configuration, RTP and maximum win are not stated, and the Wild rule does not promise a winning combination. It should appeal to players who want a bonus that alters each spin’s setup, but not those expecting a fully specified payout profile from the public description alone.
