How Cluster Gems works
Cluster Gems is a 8-reel video slot.
Free Spins are triggered by scatter symbols and are where most of the game's win potential sits.
Wins are formed by clusters of 5 or more matching symbols anywhere on the grid, rather than fixed paylines.
Winning symbols are removed and new ones drop in (cascading reels), so a single spin can chain multiple wins.
Win multipliers can boost payouts during the base game or bonus round.
Every mechanic above is available to test for free in the demo before you risk real money.
