Wild symbols are special symbols in slot games that can substitute for other standard symbols to help form winning combinations. They work similarly to a joker card in a deck of cards, increasing the chances of completing a win on the reels.
In some games, wilds may also come with additional features, such as expanding to cover entire reels or adding multipliers to winnings. The exact behaviour of wild symbols varies depending on the game and provider, and full details can be found in the game’s information section within the slot window.
