Skull Island

Skull Island is an action and adventure jungle game by SPADICE with an RTP of 96%, high volatility and a maximum win of 25,000x. The game uses a 6×5 cluster-pays grid, so winning combinations form from symbols that connect orthogonally rather than diagonally. Matching clusters of five or more symbols pay, with larger groups awarding bigger rewards.

Wins trigger tumbling clusters that clear from the board and allow new symbols to fall into place, creating chains of consecutive wins from a single spin. The Sheet is the wild symbol and carries a multiplier ranging from x2 to x500. It lands as either a 1×1 tile or a merged 2×2 block and substitutes for other paying symbols to complete clusters.

The Scatter (FS) symbol triggers free spins and counts once per column, with a maximum of six across the grid. It does not pay directly but instead determines the bonus tier. Free spins award 8 spins per tier, triggered by four scatters for Bonus, five for Super or six for Epic. During the feature, the Sheet multiplier accumulates into a global total and can retrigger when additional scatters land.

Four bonus buy options are available. The Super Boost costs 5x the bet and provides an alternative path to trigger the feature. The Bonus option costs 100x the bet. The Super Bonus costs 300x the bet. The Mystery option costs 500x the bet.
