What is Cluster Pays?
A slot mechanic where wins are formed by clusters of matching symbols (typically 5 or more adjacent symbols) rather than traditional paylines. Common in games with grid layouts.
Real-World Example
Sweet Bonanza (Pragmatic Play) uses a 6×5 grid where 8+ matching symbols anywhere on the grid form a win.
