The Wild Four

Zoo Busters by Fantasma Games is a colourful slot featuring rebellious zoo animals, cascading wins and bonus spins. Match 8 or more identical symbols anywhere on the six-reel grid to win—no paylines required. Each win activates the Avalanche feature: winning symbols disappear and new ones drop into place, creating opportunities for further payouts. Cascades continue until no new winning combinations form. The red gorilla is the highest-paying regular symbol, awarding 20 times the total bet for 12 or more matching symbols. The pink flamingo follows at 12 times the bet, then the green crocodile at 10 times and the blue hippo at 7.5 times for the same symbol count. To unlock 8 bonus spins, land 4 wolf Scatter symbols marked BONUS anywhere on the reels during the base game. The bonus round introduces the Zoo Keeper, a special Wild that appears only during bonus spins and substitutes for regular symbols to complete winning combinations. The Spreading Wild feature creates standard Wild symbols, which also substitute for regular symbols. Neither standard Wilds nor the Zoo Keeper can replace Multiplier, Skunk or Scatter symbols. The standout combination is high-paying animals with Wilds and consecutive cascades, allowing multiple payouts to build within a single spin.
