Avalanche

A specific branded style of cascading reels in which symbols crumble away after a win and a multiplier typically steps up with each consecutive fall.

Definition

Avalanche is a well-known variant of the cascading-reels mechanic, popularised by a particular studio, where winning symbols shatter and new ones tumble down to replace them. Its signature feature is usually a stepped multiplier that rises with each successive avalanche within a single spin, often resetting when the chain stops or between spins. Functionally it behaves like tumbling reels, but the term is commonly used to describe this multiplier-ladder presentation. As with all such features, the added excitement does not change the fact that the game is configured to keep a margin for the house over the long run.

Worked example

A win triggers the first avalanche and the multiplier shows x1. The replacement symbols form another win, so the multiplier steps to x2, then x3 on the next, so a small late win in the chain can be worth more than the first. When an avalanche produces no win, the multiplier resets.

Why it matters

For a learner, it shows how the same underlying mechanic gets different names and branding across studios. For a professional, the multiplier reset rules and free-spin interaction are exactly where Avalanche-style games gain their volatility and headline max-win potential.
