Special Features and Mechanics

Merge Up™ Mechanic

After a win, the game may upgrade part of the winning cluster into a higher-numbered symbol, increasing potential for new and better payouts. This continues through cascading wins and symbol merges.

Cascading Wins

Winning symbols disappear, and new ones drop from above. The mechanic continues until no new cluster forms, extending gameplay with each spin.

Free Spins Bonus

Triggering the Bonus

•   ⦿     4 Scatters = 15 Free Spins
•   ⦿     5 Scatters = 18 Free Spins
•   ⦿     6+ Scatters = 20 Free Spins

Multiplier Cells

Each time a cell hosts a winning cluster, it gains a 2× multiplier (stackable up to 128×). This applies to future wins landing in the same cell during the bonus round.

Retriggers

•   ⦿     Additional 4–6 Scatters during the bonus round award 5–10 extra spins.
