Cascading reels is a special feature in some slot games where symbols that form part of a winning combination disappear and are replaced by new symbols falling from above, often referred to as "cascading". This process continues until there are no new winning combinations.
This feature allows players the opportunity to win multiple times from a single spin as the new symbols can potentially create new winning combinations. Cascading reels can be particularly exciting during multipliers and free spins rounds, as consecutive wins can lead to substantial payouts.
Also known as tumbling reels, falling symbols, or avalanche reels, this feature adds an extra dynamic to gameplay and can be found in many popular online slot games. As always, check the rules of each game for specific details on how this feature works.
