How the Game Plays

Zombie Outbreak by PGSOFT plunges players into a zombie apocalypse lab with eerie green lighting and viral chaos. Wins form when three or more matching symbols land on adjacent reels from the left across the irregular 4x5x4x5x4 grid. Premium symbols include scientists, blood bags, and gas masks paying up to 5x bet; low pays are card royals from 9-A. Tumbling reels clear winners and drop new symbols for chain reactions. Expanding Wilds appear only on reels 2 and 4, growing to cover those reels while collecting one of three multipliers (up to 25x total) that apply to wins before resetting.

Free Spins Explained

Three or more Biohazard Scatters trigger 15 free spins, with +2 spins per extra Scatter. Multipliers from Expanding Wilds accumulate across spins without resetting, boosting wins. Retrigger with 3+ Scatters for 15 more spins plus 2 per additional.

Expanding Wilds Explained

Wilds on reels 2 or 4 expand to fill the reel, attach to one of three multiplier pots, and apply the total collected value to any win on that spin. Pots reset after use in base game but persist in free spins.
