Bonus Buy Battle Cascading Reels Winning symbols disappear and new ones fall into place, potentially triggering consecutive wins from a single spin. Also known as tumbling or avalanche reels. Cluster Pays Wins are formed by groups of matching symbols touching horizontally or vertically, replacing traditional paylines with a grid-based win system. Common in games with 6x6 or 7x7 layouts. Expanding / Infinity Reels Reels that grow taller with each win or add entirely new reels, expanding the play area with no fixed limit. The Infinity Reels variant, pioneered by ReelPlay, can theoretically extend forever. Hold & Spin Triggered when a set of special symbols lands on the reels. Those symbols lock in place while the remaining reels re-spin, giving players a chance to collect more of the triggering symbols for bigger prizes. Megaways A licensed mechanic from Big Time Gaming where the number of symbols on each reel changes randomly with every spin, generating anywhere from a few hundred to up to 117,649 ways to win. Merge Up Respin Special Bets Super Spins Volatility Switch Ways-to-Win Instead of fixed paylines, wins are counted by matching symbols appearing on adjacent reels from left to right.
