Forgotten Island Megaways opens an expedition to a tropical island dominated by a colossal gorilla. Launched publicly on 26 January 2021, this slot combines variable-height reels, cascading wins and a multiplier that can gather momentum both in the base game and during free spins.

The development is credited to All41 Studios, now named ALL FOR ONE Studios. Microgaming handled distribution at launch; this catalogue is now operated by Games Global. This distinction matters here: the distributor's name often appears in lobbies, but the creation of the game belongs to studio All41.

The essential benchmarks of Forgotten Island Megaways

The game is based on 6 reels and up to 117,649 ways to win. Its reference RTP reaches 96.25%, its volatility is high and the maximum win is set at 7,000× the bet on a single spin. A 92% version is also distributed, making the operator's paytable more important than the game name alone.

Forgotten Island Megaways — grille tropicale à six rouleaux et compteur de façons de gagner

A Megaways grid that changes with every spin

Reels 1 and 6 can display up to seven symbols, while the four central reels hold up to six. A horizontal reel positioned above reels 2 to 5 adds one position to each of them. The height varies from spin to spin, so that the number of active ways changes before each rotation.

Combinations connect identical symbols on adjacent reels, from left to right. After a win, the Rolling Reels feature removes paying symbols then drops new icons into the empty spaces. The sequence continues as long as a new combination is formed, without requiring an additional bet for each cascade.

The Wild compass replaces all paying symbols, but not the gorilla scatter. It appears only on the top reel and can therefore complete multiple central reels at once. The scatters participate in triggering the free feature and are also removed when a cascade is resolved.

The maximum of 117,649 ways corresponds to the most open configuration, not a permanent volume. Large symbols sometimes reduce the number of visible positions. The indicator displayed above the grid therefore provides the useful reference for the current spin, while the mechanism remains identical regardless of the height obtained.

Kong Spin gives the multiplier a head start

Kong Spin can trigger on any winning spin in the base game. The gorilla then awards a starting multiplier of ×2, ×3, ×5 or ×10. Each new winning cascade then adds one unit to this value. The multiplier's progression has no announced cap during the sequence.

In the base game, the multiplier disappears when the Kong Spin sequence ends. One exception significantly changes the value of a late trigger: if the free spins start during this feature, the value already reached is transferred to the bonus. It then replaces the ordinary start at ×2 and continues its progression with each cascade.

Free spins, new scatters and feature buys

Four scatters award 10 free spins, then each additional scatter present during the trigger adds two spins. During the bonus, scatters focus on the top reel: three add three and four add four. The multiplier increases after each winning cascade and retains its value between free rotations.

The feature buy, when permitted, offers three entry points. A cost of 80× the bet starts the bonus at ×2; 120× gives a random start at ×3 or ×5; 150× gives ×5 or ×10. This option is not available in all jurisdictions and its cost must be compared to the planned budget, as it triggers the feature without guaranteeing its result.

RTP, volatility and limits actually offered

The theoretical reference RTP is 96.25%. A 92% configuration is also operated by some players. These percentages describe an average return calculated over a very large number of spins; they predict neither the duration of a session nor when Kong Spin or free spins will appear.

The high volatility concentrates more value on strong sequences and accepts less regular winning stretches. The observed versions start at £0.20, but their ceiling varies depending on the casino. The maximum of 7,000× applies to a single spin win; it remains theoretical and does not automatically compensate for a series of bets or a costly bonus purchase.

Which player profile is Forgotten Island Megaways for?

The title suits players who like reading a variable grid, following cascades and watching a multiplier evolve rather than receiving a fixed bonus. The Megaways slots guide allows you to compare this formula to other games based on changing height reels, without confusing the maximum number of ways with a guaranteed win frequency.

Forgotten Island Megaways stands out above all due to the possible transition of an already increased Kong Spin to the free spins. Before a game, the three useful checks remain simple: check the RTP of the open version, adjust the total bet and confirm the eventual availability of the feature buy. The slots catalogue then offers a point of comparison with less volatile profiles or more fixed grids.
