Bonus Features

Zombie Lab is packed with exciting bonus features that enhance gameplay and increase winning potential:

  • Free Spins: Triggered by landing a barrel of blue toxic waste symbol under a lit candle, turning the beautiful assistant into an extra wild symbol during the free spins.
  • Exploding Wilds: If a Blast Bonus symbol of oxygen bottles appears with a candle on the same reel, it explodes and can turn up to 3 entire reels wild, substantially increasing the chances of winning on multiple lines.
  • Pick-a-Zombie Bonus Game: Activated by landing three or more bio-hazard symbols, players pick a zombie from tubes to win coin prizes with a captivating animation of the zombie escaping.


The Zombie Lab slot features a mix of thematic and traditional symbols that combine to form winning combinations:

  • High-value Symbols: Characters including the bearded scientist, his assistant, and a heroic guy with a gun. These symbols offer higher payouts.
  • Lower-value Symbols: Playing card icons (J, Q, K, A) stylized as elements on the periodic table to match the scientific theme.
  • Special Symbols: Wilds, scatter (bio-hazard symbol), and bonus symbols (oxygen bottles and toxic barrels) that trigger the game’s special features.


The Zombie Lab slot offers a range of payouts depending on the combination of symbols landed. Here is a simplified payout table:

Symbol 3 of a Kind 4 of a Kind 5 of a Kind
Heroic Guy $50 $100 $150
Scientist $30 $60 $90
Assistant $20 $40 $80
Wild Symbol Substitutes Substitutes Substitutes


Zombie Lab allows players to select between 5 or 10 paylines, giving them control over their betting strategy and potential winnings. Paylines must be formed starting from the leftmost reel to right, with payouts depending on the symbol combination and the initial bet amount. This flexibility allows for both conservative and aggressive betting styles.
