Zoo Busters Combines Avalanche Wins with Three Wild Animal Features

Zoo Busters turns a cartoon zoo into a 6×5 Pays Anywhere slot where groups of eight or more matching symbols create wins. Winning symbols disappear through the Avalanche mechanic and new symbols fall into the empty positions, allowing additional wins to form within the same sequence. Fantasma Games adds Multiplier symbols and three distinctive feature symbols — Molotov, Skunk and Piranha — before taking the action into Bonus Spins and a stronger Super Bonus Spins round.

Zoo Busters Game Details

Zoo Busters Base Gameplay

Avalanches Keep Pays Anywhere Wins Moving

Zoo Busters pays when at least eight matching symbols appear anywhere on the grid. Symbols involved in a winning combination are removed, with new symbols dropping into their places to create the next Avalanche.

Multiplier symbols can appear anywhere on the reels with values of 2×, 3×, 5×, 7×, 10×, 25×, 50× or 100×. When multiple Multiplier symbols appear during the same Avalanche sequence, their values are added together, and the resulting value multiplies the total win from that sequence.

Three Special Symbols Disrupt the Reels

The Spreading Wild Feature is activated by a Molotov symbol. Once triggered, up to four randomly selected paying symbols are transformed into Wilds.

Zoo Busters Spreading Wild Feature

The Skunk Bomb Feature starts when a Skunk lands anywhere on the reels. It transforms adjacent paying symbols into one randomly selected paying symbol.

Piranha Shelling works differently. A Piranha clears between 2 and 12 random paying-symbol positions before another Avalanche begins. The number of cleared positions becomes the Piranha multiplier applied to the total tumble win, while any Multiplier symbols in play are added together before multiplying the result.

Bonus Spins Introduce the Zoo Keeper

Landing four Bonus symbols anywhere on the base-game reels awards 8 Bonus Spins. During the feature, a Zoo Keeper symbol can appear, and each Zoo Keeper contributing to a win adds one extra Bonus Spin.

Collecting 10 winning Zoo Keeper symbols during the session unlocks Super Bonus Spins at the end of the regular bonus.

Zoo Busters Feature Overview, Bonus Spins

Super Bonus Spins Guarantee a Multiplier

During Super Bonus Spins, every spin receives a guaranteed multiplier of 1×, 5×, 10×, 25×, 50× or 100×. That value multiplies the total tumble win for the spin.

If regular Multiplier symbols also land, their values are added to the guaranteed multiplier, increasing the multiplier applied to that spin's tumble result.

Bonus Store Offers Three Feature Options

The official rules also include a Bonus Store. Scatter Boost costs 2× the corresponding bet and doubles the chance of triggering Bonus Spins.

Players can also buy 8 Bonus Spins for 80× the bet or 6 Super Bonus Spins for 200× the bet. The rules list RTP values of 96.15% for Scatter Boost, 96.27% for purchased Bonus Spins and 96.34% for purchased Super Bonus Spins.

Zoo Busters has a standard theoretical RTP of 96.05%, Medium-High volatility and stakes from €0.10 to €3,000. Fantasma Games has scheduled the slot for release on October 8, 2026.
