Sticky Wild

A sticky wild is a wild symbol that locks into its position on the reels and stays there for one or more subsequent spins, rather than disappearing after a single spin like an ordinary wild. As a wild it substitutes for paying symbols to complete winning combinations; the 'sticky' property means each one you land is banked for the spins that follow, so wild coverage accumulates rather than resetting. The feature appears most often inside free-spin bonus rounds, where it builds toward increasingly powerful payouts as the round progresses. Worked example: you trigger ten free spins on a five-reel slot with sticky wilds. On spin one a wild lands on reel two and holds. On spin four a second wild lands on reel four and also holds. From spin four onward two reels are permanently wild for the rest of the round, sharply raising the chance that the remaining symbols complete full-line wins. By the closing spins the screen can be carrying several locked wilds at once, which is where the biggest hits in this mechanic occur. The attraction is that value compounds: the longer the round and the more wilds that stick, the higher the ceiling on the final spins. The common mistake is over-valuing the feature in the base game, where one stray wild that vanishes next spin does little — the mechanic only realises its potential when stickiness is active across a free-spin sequence. As with all slot features, the trigger frequency is governed by the reel maths and cannot be influenced by stake or timing, so treat it as entertainment and set limits. Compare with the wild symbol, the scatter and slot volatility.
