Wild Symbol Explained: Multiplier, Transforming, Sticky and Expanding Wilds

Every wild symbol substitutes for other symbols, so why do two games with a wild pay so differently? Method: the game pages and published descriptions of four studios (JILI, PG Soft, Pragmatic Play and Betsoft) were read for what their wilds do besides substituting. Result: five distinct behaviours appear in those records, and the second job a wild does matters more to a session than the substitution itself.

Wild symbol types in the studios’ records

The multiplier row is worth working through, because the effect compounds. On that doubling rule, two Golden Jokers in a win make 2 x 2 = 4x, three make 8x, and five make 32x. That is why a single line can jump from small to large on a multiplier wild, and why the paytable’s top win often depends on them.

JILI’s page adds one more rule: inside Super Ace’s Free Game, each multiplier is twice its main-game value, so the same golden-card wild can complete a win worth more inside the feature than outside it. The collecting row behaves in the opposite way to most wilds. In Big Bass Bonanza’s collect feature, the money fish pay nothing on their own; the round only pays when the fisherman wild lands to gather them.

Sticky and expanding wilds

Two more types appear in many paytables, though none of the slice games on this site is built around them.

1. Sticky wild: stays on its position for the following spins, often for a whole free-spin round, so later spins start with a wild already in place.
2. Expanding wild: grows to cover its whole reel when it lands, turning one wild into three, four or five positions at once.

Problem: a wild lands and the win is smaller than expected. Fix: read whether that wild multiplies or merely substitutes; on a substitute-only wild, the line pays exactly what the same line of ordinary symbols would.

Wilds and scatters do different jobs, and the second is easy to confuse with the first. The scatter symbol rules for free spins cover the symbol that starts features, and the wider vocabulary sits in the casino terms glossary entries. On PH444, Super Ace, Wild Ace, Mahjong Ways, Lucky Neko and Big Bass Bonanza each sit in their own studio’s lane on the studio lanes on the slot games page.
