Sticky Wild

Sticky wilds are wild symbols that remain locked in position for a set number of spins or for the duration of a bonus feature. Once triggered, they substitute for other symbols on every subsequent spin, increasing winning potential with each new sticky wild added. Common in free spin bonuses, sticky wilds can fill entire reels over multiple spins. Some games feature 'semi-sticky' wilds that move position between spins (Walking Wilds). Sticky wilds are particularly valuable in bonus rounds where multiple can accumulate, creating increasingly powerful combinations. Games like Dead or Alive 2 are famous for their sticky wild free spins.
