Highlight Features

Cluster Pays

The Cluster Pays system is an innovative winning method that completely breaks the traditional slot concept of 'lines'. In a typical slot, symbols must be placed sequentially from the left on a designated payline to be considered a win. However, in the Cluster Pays method, there are no lines at all. Instead, symbols like candies or jellies cascade down onto a large grid (usually 5x5 or larger). There is only one condition for a win: identical symbols must connect horizontally or vertically to form a cluster.

Symbol Upgrade

Symbol Upgrade is a powerful feature that progressively converts low-value symbols on the reels into higher-value ones as the game proceeds. The core of this feature is not just a one-time symbol change, but a 'growth' structure where lower-tier symbols are permanently removed from the reels and replaced by higher-tier ones. This drastically increases the average expected payout of the reels towards the end of the round.
