Short answer: After a win, the winning symbols disappear and new ones drop in, which can create another win from the same stake.
Slots that use it
How a tumble resolves
- Symbols land on the grid.
- Any win is paid and its symbols removed.
- Symbols above fall down; new ones fill the top.
- Steps two and three repeat until nothing connects.
However long it runs, a tumble sequence is one spin and costs one stake.

What it means for play
Tumbling slots feel busy. Small wins are common and chains of two or three tumbles happen often, yet the totals stay modest until a multiplier applies. That is how a game can seem to be paying constantly while the balance falls.
Other names
Cascading reels, avalanche and rolling reels all describe the same mechanic.
