Tumble Feature

The tumble feature (also called avalanche, cascade, or collapse) is a mechanic where winning symbols are removed from the reels after paying out, and symbols above them drop down to fill the gaps. New symbols then fall in from the top, potentially creating additional wins from a single paid spin. Many tumble feature slots increase a multiplier with each consecutive tumble. This creates the potential for massive wins when long tumble chains occur. The tumble feature is central to popular slots like Sweet Bonanza, Gates of Olympus, and Sugar Rush. It pairs particularly well with cluster pays mechanics.
