How to play Zombie Outbreak

Zombie Outbreak, developed by PG Soft, is a 6x6 grid slot that uses an all-ways mechanic with 1,600 ways to win. Winning symbols engage a cascading mechanic, removing winning symbols and allowing new ones to fall, potentially creating additional wins from a single spin.

Set your desired bet: Adjust your stake using the controls provided in the game interface.
Spin the reels: Initiate a spin and watch for matching symbols to land on adjacent reels from left to right.

What is a good strategy for Zombie Outbreak?

Zombie Outbreak has a 25.25% hit rate, indicating that approximately one in four spins will result in a win. The game's high volatility suggests that a significant portion of the total return is found within the bonus features, rather than frequent smaller base game wins. Players can directly influence bonus entry via Bonus Buy options: 75x for Infection Free Spins, 150x for Survivor Free Spins (with a guaranteed stacked Wild reel), or 300x for a combined super feature. Choosing the 150x buy provides a more predictable bonus experience due to the stacked Wild reel, while the 75x and 300x options offer higher variance through the spreading Wilds mechanic. Utilizing Bonus Buy targets specific feature outcomes.
