How the Game Plays

Twisted Lab, created by Hacksaw Gaming, introduces players to the eccentric world of Mr. Melker and his robotic companion, Pat the Rat. Set within a neon-soaked, futuristic laboratory, the action unfolds on a 5x5 grid with 19 fixed paylines. Wins are formed by landing three or more matching symbols—ranging from eyeballs and teeth to brains and mushrooms—starting from the leftmost reel. The visual aesthetic is a blend of dark industrial elements and vibrant purple and turquoise fumes, creating a "mad scientist" atmosphere.

RotoGrid™ and Oozing Beakers Explained

The central innovation of the game is the RotoGrid™ symbol. When this symbol appears, it carries up to four charges, each triggering a 90-degree clockwise rotation of the entire grid. Before the rotation, initial wins are collected; after the turn, the new configuration is evaluated for further wins. This mechanic is often paired with Oozing Beakers. When the grid rotates, these beakers break and spill "ooze" down to the bottom of the grid. Any position covered by the ooze transforms into a Wild symbol. Blue Beakers add multipliers up to 100x, while Pink Beakers multiply existing values, potentially leading to significant combinations.

Free Spins and Bonuses Explained

There are two primary bonus rounds. Landing three FS scatters triggers the "Unleash the Ooze!" feature, awarding 10 free spins with an increased frequency of RotoGrid™ symbols and Oozing Beakers. If four FS symbols land, "The Twist of the Twisted!" bonus begins. This is a specialized respin feature with three lives where the grid only contains Twisters, Collect symbols, and RotoGrid™ symbols. Twisters carry multipliers on all four sides, and rotating the grid with RotoGrid™ charges changes which multiplier is active at the top. Collect symbols then gather these values to build the final win total.
