How the Game Plays

Monster Lab by Evoplay transports players into the cluttered workshop of a mad scientist whose latest experiment has backfired, turning him into a bug-eyed purple creature. The action takes place on a 5x3 grid where various colorful specimens are preserved in liquid-filled tubes. Wins are achieved by landing matching monsters or scientific symbols across 20 fixed paylines. The visual style is highly animated, with the transformed professor standing beside the reels, reacting to every win and feature trigger with comical expressions.

Free Spins Explained

The free spins feature is triggered by landing three or more Red Molecule scatter symbols anywhere on the reels. Depending on the number of scatters, players receive 15, 20, or 25 free spins. Once the round is complete, the game introduces a unique "Extra Bonus" phase. Players are presented with three mystery cards and must select one to reveal a final reward. This prize can be a 2x or 3x multiplier applied to the total accumulated winnings from the free spins session, or an additional 20 free spins.

Laboratory Bonus and Special Features

Landing three or more Horned Monster bonus symbols triggers an interactive second-screen game. In this mode, players help the scientist conduct experiments by clicking to drop monsters into specific beakers, with each successful drop awarding a multiplier up to 5x. The game also includes a DNA Wild symbol that can expand to occupy an entire reel, significantly increasing the potential for multiple winning combinations. Finally, a gamble feature is available after any base game win, allowing players to guess between two results for a chance to double their payout.
