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.

Retrigger

A Retrigger means winning additional free spins by landing scatter symbols again during a free spins bonus round. Furthermore, some slots adopt an 'unlimited retrigger' system, which means there is no limit to the number of times it can re-trigger. In theory, if luck is on your side, the free spins can continue indefinitely, making it one of the most powerful features a slot can have.

Bonus Buy Efficiency

Average Bonus Buy Price

This slot's bonus buy price sits within the usual range for comparable slots. Buying the feature can be a reasonable option if your goal is to reach the free-spin round without waiting for a natural trigger. The trade-off is that you skip the base-game spins that would normally happen before the feature, including any wins or volatility from that part of play.
