Slot Features
Browse common slot features and bonus systems, from free spins and multipliers to bonus buys, wild modifiers and jackpots. Each page explains the feature and shows games where it appears.
-
Respins A respin repeats the whole grid or selected reels while the remaining positions hold in place, triggered by the game or bought for a price.
- Free Spins Retrigger
A retrigger adds extra free spins while the bonus is already running, usually when the original trigger symbols land again during the round.
- Persistent Multipliers
A persistent multiplier keeps its accumulated value across spins or a whole bonus, continuing to grow instead of resetting after each event.
- Increasing Multipliers
An increasing multiplier climbs with every qualifying event, such as consecutive cascades or bonus wins, and resets when the driving sequence ends.
- Mystery Symbols
Mystery symbols land as hidden placeholders and reveal simultaneously into one random symbol, turning scattered positions into synchronized wins.
- Wild Reels
Wild Reels is a modifier that turns one or several entire reels wild for a spin, guaranteeing substitution on every row of the affected reels.
- Random Wilds
Random wilds are added to the grid by the game rather than landing on the reels, appearing before evaluation or after a spin resolves.
- Stacked Wilds
Stacked wilds land as vertical blocks covering several rows of a reel at once, at full size turning the entire reel wild for that spin.
- Shifting Wilds
Shifting wilds relocate between spins in defined or random patterns, staying in play while changing position rather than walking steadily off the grid.
- Walking Wilds
A walking wild moves one reel sideways on every spin until it exits the grid, frequently granting respins for as long as it stays in play.
