What is the Cluster Pays Mechanic?

Cluster pays is a trademarked game mechanic originally developed by NetEnt. The rules and ludemes are pretty similar to grid slots, which use a payout model based on grouped symbols instead of traditional paylines.

A cluster typically comprises a group of symbols placed adjacently. When a cluster of matching symbols appears across the reels, it forms a winning combination. The payout depends on the size of the cluster formed, with larger clusters offering higher rewards.

These slots usually come with the cascading reels feature. Once a cluster forms, the winning symbols are replaced by new symbols to create new clusters, increasing the chances of winning larger rewards with a single spin. The cascading effect continues as long as new clusters form. Players usually need at least 5 symbols in a cluster to get paid.

Contrary to traditional slots that rely on predefined paylines where specific combinations must align to secure a win, cluster pays slots eliminate the need for paylines, offering more flexible and varied ways of securing wins.

Cluster slots are usually more engaging than traditional slots due to the combination of the cluster pays and cascading reels mechanics. This continuous action of forming new clusters keeps the players engaged for extended durations.
