EDITORIAL OVERVIEW

How tumbling reels work

Cascading reels remove qualifying winning symbols and replace them before the original round ends. Providers also use names such as tumbles and Avalanches for related implementations.

The key distinction is round continuity. A refill following a win commonly remains part of the initial paid spin, so each visual drop should not be counted as a separate wager.

Some games increase a multiplier during consecutive cascades, while others keep the same values or add feature-specific modifiers. The reset point can differ between the base game and free spins.

Wait until no further qualifying combination appears and control returns before recording the complete virtual result. A long cascade can still finish without revealing anything about the next independent round.

FREQUENTLY ASKED QUESTIONS

Questions about this topic

Are cascading reels, tumbles and Avalanches the same?

They are provider terms for closely related refill mechanics, but exact removal, multiplier and stopping rules can differ.

Is every cascade a new paid spin?

Usually no. Consecutive cascades commonly belong to one initial round.

Do cascade multipliers always persist?

No. Some reset after the round and others persist only during a bonus.

Can a cascade continue without a limit?

It continues only while the game's qualifying conditions are met; the paytable defines any additional limit.
