Twisted Lab Demo & Review

Twisted Lab review

Twisted Lab is a 5x5, 19-line slot that rotates the whole grid. A RotoGrid symbol lands with one to four charges, and each charge turns the grid 90 degrees clockwise, with paylines recalculated after every rotation, so a spin that looked like a miss can turn into a winner.

Mr. Melker and Pat the Rat run the lab, which nods to other Hacksaw characters such as Canny and the Chaos Crew. Hacksaw rates it 4 out of 5 for volatility, with a 15,000x maximum. It's one of the studio's most original mechanics.
