Twisted Lab

Hacksaw's Twisted Lab is a video slot featuring a 5×5 grid and 19 fixed paylines, set in the chaotic environment of a mad scientist's laboratory. This theme is brought to life with bubbling beakers, bizarre experiments, vibrant neon colors, and a quirky rat assistant. The game introduces the RotoGrid™ mechanic, which can rotate up to four times; when activated, it allows the entire grid to spin in 90-degree angles, potentially generating new paylines after the initial win is settled. Oozing Beakers are linked to this mechanic; when the grid rotates, any beaker that cracks spills ‘ooze’ and transforms those positions into Wild symbols. Blue beakers can provide multipliers from 2× to 100×, while pink beakers enhance those multipliers, and purple beakers spill ooze without offering any multipliers. Twisted Lab includes two distinct bonus rounds: “Unleash the Ooze!” is activated by landing three FS scatter symbols, awarding 10 free spins with heightened opportunities for RotoGrid™, FS scatters, and Oozing Beakers. The second bonus, “The Twist of the Twisted!” is triggered by four scatters and initiates a special mode with three “lives,” where only Twisters, Collect symbols, RotoGrids, and non-paying symbols appear. In this mode, Twister symbols reveal four multiplier values, with the upward-facing value becoming active, while collectors can accumulate all active multipliers. Whenever a Twister or Collector lands, lives are reset, and the bonus concludes when all lives are exhausted without landing one of those symbols. Additionally, there is a Feature Buy option that allows players to directly enter one of the bonus rounds or feature spins. The maximum potential win in the game is 15,000× the bet, achievable in any game mode.
