A wild is a symbol that substitutes for other paying symbols to help form a win. Land four cherries and a wild on a line, and the game counts it as five cherries.
Wilds usually do not replace scatters or bonus symbols, so they cannot trigger features on their own; the paytable says exactly what they cover. Some wilds pay as a symbol in their own right, some appear only on certain reels, and some carry a multiplier that boosts any win they complete.
Many features are wilds with extra behaviour:
- Expanding wilds grow to fill the whole reel.
- Sticky wilds stay in place for several spins.
- Walking wilds move one position each spin.
- Stacked wilds land in vertical blocks.
Wilds make wins more frequent when they appear, but they are counted in the game's maths, so they do not raise the RTP beyond what is published.
