Twisted Lab RotoGrid Slot RTP, Details & Wager Limits
The action in the Twisted Lab RotoGrid slot game plays out on a 5×5 grid with 19 paylines. Land 3, 4 or 5 matching symbols or wilds from left to right in a payline, starting from reel 1, to form a winning combination.
You can join Mr. Meckler in his lab at bet levels of between 10p and £100 per spin. Use the arrows next to the spin button to adjust your bet size.
Autoplay is available where it’s allowed. This lets you run between 10 and 1,000 autospins. You can also set win and loss stop limits. This feature isn’t available if you’re playing at UK online casinos.
The Twisted Lab RotoGrid RTP is a better than average 96.30%. The game’s variance is high, scoring 4 out of 5 on the volatility scale. The Twisted Lab max win is 15,000 x stake.
Theme – Enter the Eccentric Doc’s Laboratory
Mr Melker’s laboratory is the setting for Twisted Lab. The bearded scientist watches over the action on one side of the reels, and Pat the Rat oversees operations on the other. There’s a neon glow to the visuals here, with pink and aqua dominating the colour scheme.
The cartoon-style symbols are made up of ingredients Mr. Melker might use in one of his magical potions. Look out for feather, leaf, egg, mushroom, octopus tail, eye, teeth and brain symbols. There are also three beaker symbols, all wild. You need to land 5 of the same beaker in a payline to form a winner. There are also Rotogrid and FS scatter symbols.
I really liked the visuals here. They stand out nice and crisply against the dark backdrop, even if you’re playing on a handheld device with a small screen. It’s a similar story with the soundtrack which is a perfect fit for a slot with this theme.
I give the Hacksaw Gaming design team a big pat on the back for the sound and visuals in Twisted Lab.

Twisted Lab RotoGrid Mobile
You can play Twisted Lab on smartphones and tablets as well as desktop and laptop computers. The bold design works superbly on devices with a smaller screen. This is a slot that’s ideally suited to mobile play.
Twisted Lab RotoGrid Bonus Features
As you’d hope from a slot where a mad scientist takes centre stage, there are some innovative features on offer in Twisted Lab. Chief among them is the RotoGrid, where the reels shift 90 degrees at a time. Breaking beakers can turn wild with multipliers attached. There’s also a free spin bonus and the potentially explosive Twist of the Twisted bonus.
RotoGrid
The RotoGrid symbol can land with between 1 and 4 charges attached. For each charge, Pat the Rat pulls a lever which rotates the reels by 90 degrees. A new payout calculation is made with each rotation. In effect, these are extra free spins.
Oozing Beakers
Keep a special eye out for the three brightly coloured beaker symbols. When the RotoGrid is active, any beakers are smashed and their liquid oozes to the bottom of the grid. All symbol positions covered in ooze turn wild. They can also come with multipliers attached.
- Purple Beaker Ooze = No multipliers
- Pink Beaker Ooze = x2, x3, x4, x5, x10
- Blue Beaker Ooze = 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 100x multipliers
- If Ooze lands on top of Ooze, the values of any multipliers are added together.
Unleash the Ooze Free Spins Bonus Feature
Land 3 FS scatter symbols on the same spin to activate the Unleash the Ooze Bonus. You’ll then go on to play 10 free spins. Expect to see the RotoGrid, FS symbols and Oozing Beakers more often than in the base game.
The Twist of the Twisted Bonus Feature
Trigger this rather unusual feature by landing 4 FS scatters on the same spin. The action plays out on a game grid made up solely of blanks, Blue Twisters, Pink Twisters, Collect and RotoGrid symbols. Each Twister that lands comes with 4 multiplier values attached. The value at the top of the Twister is the currently active multiplier.
Pink Twisters can be worth 1x, 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 1,000x.
Blue Twisters can be worth 1x, 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 1,000x.
Each time a RotoGrid symbol appears, the Blue Twisters move 90 degrees, changing the live multiplier. Pink Twisters rotate with each new spin.
Land a Collector symbol, which awards the combined value of any Twisters at the end of that spin. All Twisters remain on the grid until they’ve been collected or the round ends.
You’ll start the Twist of the Twisted feature with 3 lives. You’ll lose a life with each free spin. That number resets each time a Collector or Twister symbol lands.
At the end of the round, the current Twister values on the grid and the value collected by any Collect symbols are combined and multiplied by your bet to give you the final payout.

None of the Bonus Buy options are currently available to players in the UK.
Twisted Lab RotoGrid Verdict: Great Design and Innovative Gameplay
Chemistry was never my subject at school. I found the Twisted Lab much more to my liking, though. The gameplay is unusual and offers plenty of variety. I didn’t have to wait long for the RotoGrid to appear, and the other features landed regularly enough to keep things interesting.
The Twist of the Twisted Bonus has some real potential if the multipliers fall nicely. The Oozing Beakers can also really spice up the action.
I really liked the design in Twisted Lab, too. The sound and visuals complement each other perfectly and really fit the features. The numbers stack up well. The 96.30% RTP is better than average, the volatility of 8/10 isn’t too ridiculous, and the 15,000 x stake max win packs a decent punch.
Put all that together, and Hacksaw Gaming has come up with an impressive concoction, and a trip to the Twisted Lab is recommended.
