Cascading Wins (Tumble Feature)

Cascading wins (also called tumbling reels, avalanche, or collapsing wins) is a slot mechanic where winning symbols are removed from the reels after a payout, and new symbols fall from above to fill the gaps. This can create chain reactions of multiple wins from a single spin. Some games increase a multiplier with each consecutive cascade, making extended chains extremely valuable. Popular slots using this mechanic include Sweet Bonanza, Gonzo's Quest, and Reactoonz. The cascading mechanic pairs especially well with cluster pays and Megaways formats, creating exciting win sequences.
