What the feature means
Winning symbols clear and new symbols enter the grid. The exact trigger, eligible symbols and limits belong to each slot’s own rules, so the same label can behave differently across titles.
How to evaluate it
Trigger
Identify the exact symbols, counts or events required.
Duration
Check whether the feature lasts one result, several spins or a complete bonus round.
Interaction
Note whether other Wilds, multipliers or respins can combine with it.
Limits
Review maximum awards, caps and jurisdiction-specific availability.
