About this Slot
Skull Island is an action and adventure jungle-themed slot from SPADICE with an RTP of 96%, high volatility and a maximum win of 25,000x.
The game uses a 6x5 cluster pays grid where symbols connect orthogonally only. Clusters of 5 or more matching symbols pay, with larger groups awarding higher prizes. Winning clusters are cleared away in a tumble, dropping new symbols into the gaps to create additional winning combinations in a single spin.
The wild symbol substitutes for paying symbols and carries a multiplier ranging from 2x to 500x. Wilds land as single 1x1 blocks or merged 2x2 blocks on the grid.
Scatters trigger free spins, with a maximum of 6 scatters counted once per column. Four scatters trigger the Bonus tier, awarding 8 free spins. Five scatters trigger the Super tier, also awarding 8 free spins. Six scatters trigger the Epic tier, awarding 8 free spins. During the free spins round, wild multipliers accumulate globally across the entire feature. Additional scatters landing during free spins retrigger the bonus with further spins.
Four bonus buy options are available. Super Boost costs 5x the bet. Bonus costs 100x the bet. Super Bonus costs 300x the bet. Mystery costs 500x the bet.
