What Is Twisted Lab?

In this cracked world, players meet Mr. Melker and his helper, Pat the Rat, inside an eccentric laboratory setting where madcap experiments are being cooked up at every turn. The game's punk-inspired neon-on-dark aesthetic is reminiscent of past Hacksaw hits like Chaos Crew and Chaos Crew 2, setting the perfect stage for this unconventional adventure into mad science.

The rotating 5-reel, 5-row grid might induce a touch of motion sickness in some players, but for those who can handle the spin, it offers 19 paylines and a genuinely high-volatility thrill ride. Beakers substitute as Wild symbols throughout regular play, worth 10x the bet for five landing on a payline.

The RotoGrid Mechanic

The RotoGrid is something of genius, cooked up only by the maddest of scientists, and at times you can ever so slightly lose your bearings watching it work — but the potential that comes as a result is worth that tenfold. The standout strength here is that RotoGrid isn't merely decorative: the grid rotation system genuinely creates additional winning opportunities that a standard, static payline evaluation simply couldn't offer, reimagining the classic Hold and Win format in a way few other studios have attempted.

Unleash the Ooze! and The Twist of the Twisted

During the game's dedicated bonus mode, only Blue Twisters, Pink Twisters, Collect Symbols, RotoGrid symbols, and ghostly non-winning symbols appear on the reels, with extra symbols carrying multipliers ranging between 1x and a striking 1,000x. Players collect these symbols to refill lives throughout the round, extending an especially hot sequence considerably. The Twist of the Twisted represents the top-tier mode, triggering an exciting new level to the Hold and Respin format at the cost of 200x the bet, running a 96.33% RTP.

Five feature buy options give players granular control: BonusHunt FeatureSpins (3x, 5x more likely trigger, RTP 96.28%), Oozing RotoGrid FeatureSpins (75x, guarantees at least 2 Blue Oozing Beakers and 1 RotoGrid symbol, RTP 96.27%), Unleash the Ooze! (100x, RTP 96.29%), and The Twist of the Twisted (200x, RTP 96.33%).

RTP, Volatility and the Realistic Odds

Default RTP is 96.30%, positioning this firmly in the high-variance space where wins are less frequent but more substantial when they occur. Volatility is rated medium-high to high (4 out of 5), and the house edge of 3.70% works in the player's favour toward that eventual 15,000x cap.

The 15,000x max win is achieved through collected multipliers reaching their maximum 1,000x value compounding during an especially strong The Twist of the Twisted sequence, and is achievable in all game modes. Bets run $0.10 to $100 per spin.

Our Verdict

Twisted Lab represents exactly the kind of innovation that defines Hacksaw Gaming's portfolio at its best — the RotoGrid mechanic combines distinctive theming with genuinely novel mechanics into an experience that stands apart from similar laboratory-themed releases across the market. The rotation system's ability to create fresh winning opportunities beyond static payline evaluations is the standout strength here, and pushing the boundaries of slot design this way pays off with a substantial 15,000x ceiling. If this game is a true benchmark of where slots of tomorrow are heading, things really are about to get turned on their head.
