A cluster mechanic where 4 or more identical symbols dropping next to each other vertically or horizontally form a cluster — a winning combination. After it is paid, symbols of the cluster merge one level up. There are 9 symbol levels in the game. The win amount depends on the level of merging symbols and their number.

A 9th-level symbol that can drop anywhere on the reels or form from the 8th-level symbols. 4+ Scatters trigger the round of Free Spins.

4, 5, and 6+ Scatters start 15, 18, and 20 Free Spins. Throughout the round, the cells where a winning cluster is formed are marked. Next time a winning cluster occurs in a marked cell, the cell gains an x2 multiplier. The multiplier increases by x2 with every new win, up until x128. 4, 5, and 6+ Scatters on the reels in one spin of the Bonus game add 5, 8, and 10 free spins.
