What Is a Wild Symbol in Slots?

A wild is a slot symbol that substitutes for other symbols to help form winning combinations — a bit like a joker in cards. It's one of the most common ways slots create extra wins.

How wilds work

If a wild lands where a particular symbol would complete a win, it stands in for that symbol. So two matching symbols plus a wild can pay as three of a kind. Wilds usually substitute for all regular symbols, but typically not scatters.

Types of wild

  • Expanding wild: grows to fill a whole reel.
  • Sticky wild: stays in place for several spins.
  • Stacked wild: appears stacked on top of itself on a reel.
  • Walking wild: moves across the reels each spin.

Wild vs scatter

A wild completes wins by substitution; a scatter triggers features regardless of position. They're different tools. See what a scatter symbol is and slot paylines for the full picture.
