Cluster rule
In Cluster Pays, there are no paylines. A win is awarded when a group of identical symbols touches horizontally or vertically (not diagonally) and reaches a minimum size — typically 5 symbols.
The bigger the cluster, the higher the payout: the table grows in steps (5, 6, 7… symbols) all the way up to a full screen. The grid here is larger than the classic 5×3 — often 6×5 or 7×7.
Why clusters get along with cascades
After a win, the cluster symbols are removed and new ones fall from above (tumble/cascade). This can form a new cluster from the same spin — the chain continues as long as there are wins.
The bundle delivers long sequences in a single paid spin and a clear "snowball" effect. In our engine, the cascade is deterministic and provably-fair: the entire chain can be recalculated from the seeds.
Cluster vs lines and ways
Lines are fixed paths from left to right. Ways — any symbol on adjacent reels. Cluster — grid adjacency in all directions except diagonal, plus group size.
Clusters are visually more dynamic: a win appears as a "blot" on the screen, not an abstract line. Combined with cascades, this is one of the most engaging modern mechanics.
