Cluster Pays
An innovative slot machine mechanic where wins are formed by landing a group (or cluster) of matching symbols adjacent to each other, rather than on traditional paylines.
Cluster Pays is a game engine popularized by developers like NetEnt. Instead of lining up symbols on fixed lines, a win is awarded when a cluster of identical symbols (typically 5 or more) land touching vertically or horizontally.
When a winning cluster is formed, it often triggers a cascading or avalanche feature, where the winning symbols disappear and new ones fall into place, allowing for multiple wins from a single spin. This dynamic mechanic creates a very different gameplay feel from traditional line-based slots.
