How the Game Plays

Zombie Lab, developed by Octavian Gaming, immerses players in a post-apocalyptic scientific facility where an experiment has gone dangerously wrong. The 5x3 grid is set against a backdrop of glowing green chemicals, test tubes, and monitors. Symbols include thematic characters like a lead scientist, a brave survivor with a shotgun, and his assistant, alongside low-value playing card icons designed to look like elements from the periodic table. Winning combinations are formed across 50 fixed paylines, moving from left to right.

Free Spins Explained

The core attraction of this slot is its Free Spins feature, which is triggered by landing three or more bio-hazard scatter symbols anywhere on the reels. Once activated, the game can award a significant number of bonus rounds—up to 100 in some versions. During the free spins, all winnings are boosted by a 3x multiplier, offering a substantial increase in potential returns compared to the base game.

Special Features

The Zombie Wild symbol is the most helpful ally in the laboratory, as it can substitute for all regular pay symbols to complete winning lines. In some versions of the game, land-based or upgraded versions may also feature a "Pick-a-Zombie" bonus where players break open test tubes to reveal instant prizes. However, the online version primarily focuses on the high-frequency Wild interactions and the high-potential multiplier during the free spins mode.
