Twisted Lab RotoGrid Slot Overview
Our Twisted Lab RotoGrid slot review is your first stop on the journey to understand one of the most innovative Hacksaw Gaming slots - if the ways of the mad scientist can ever be understood. In this twisting laboratory, it’s not just the 5 reels but the whole grid that can turn, the beakers can ooze wilds and multipliers, and there are two bonus games: free spins and a hold-and-win-style feature, all on top of the regular 19 paylines.
Graphics and Theme
The mad scientist is an iconic figure. Victor Frankenstein and Henry Jekyll come to mind as classic examples, but there are countless others in books, film and TV. Slots often draw on popular imagery, and Twisted Lab RotoGrid has the sort of main character you’d imagine if someone said “mad scientist” to you, with the wild hair and beard, the long white coat, and the massive brain that extends outside of his head. Okay, that last one might be a bit weird, even for a mad scientist.
What scientist can work without a fully equipped laboratory? The Twisted Lab RotoGrid slot brings you to a world of strange machines and curious liquids. It’s a dark world, with the moon just visible. There are no generic card symbols here; everything is themed, including tentacles, eyeballs, brains and other lovely images. There’s another character in addition to the scientist, a bionic rat with a visor and a robotic arm. Both characters are animated.
Twisted Lab RotoGrid RTP and Variance
The top RTP of the Twisted Lab RotoGrid slot is 96.3%. The variance is high.
How to Play
An overview of the game's controls:
- Have you budgeted? Do you know your limits? Start as you mean to go on, by being responsible.
- The Twisted Lab Rotogrid bonus features are a little unusual, and even the base game has some oddities, so go to the menu and read through the rules and paytable.
- Use either the arrows or the plus and minus symbols, depending on your version, to set a sustainable wager. It starts at a 0.10 minimum.
- Run through any other settings, like sound and music, that you may want to tweak.
- Hit spin and have fun! If you need to take a break at any point, do so.
- Always play responsibly.
How to Win
There may be some peculiar additions to Twisted Lab RotoGrid, but like most modern slots, it has 5 reels. Admittedly, most 5-reel slots have 3 rows, not 5. Big Bass Bonanza Reel Action is an example of this. Twisted Lab RotoGrid also has a straightforward 19 paylines, not the more unusual mechanics a video slot might use to try to be creative. That means there are 19 ways to match symbols across the grid.
Top Wins
- It’s not immediately obvious which of the 8 paying symbols are high or low value. They’re slightly random, even if themed.
- At the bottom of the paytable are feathers and leaves, paying 0.5x your wager for 5-of-a-kind matches.
- Find 5 brains or teeth for a x5 payout.
- Beakers are wilds, but land 5 of them (they don’t pay in combos of 3 or 4) and they’ll pay x10.
- Overall, the max win available is x15,000.
Rotating Grid
A charged RotoGrid symbol can spin the entire 5x5 playing grid by 90 degrees (a quarter turn, for the non-mathematical), and each symbol has up to 4 charges. That means it could turn 180, 270 or 360 degrees overall. Each turn shifts your paylines to create more chances at winning symbols.
Top Science Slots
Oozing Beakers
Rotating the grid causes any wild beaker symbols to break and the contents to ooze over the grid. Any position touched by the ooze turns wild. Pink beakers may also ooze a win multiplier of between x2 and x10. For blue beakers, multipliers may be worth between x2 and x100. Multipliers can be combined.
Unleash the Ooze!
This is the free spins bonus, and it’s pretty simple. Find the scatter symbol 3 times, and you'll win 10 free spins. Other features are more likely to trigger while free spins are active.
The Twist of the Twisted!
Some slots would call this a hold-and-win feature, but, perhaps unsurprisingly, it has some twists. It’s played without the regular paying symbols, just blue and pink twisters, RotoGrid symbols, collector symbols and the non-paying dead symbols.
Each twister has 4 multiplier values, ranging from x1 to x1000. They rotate with the RotoGrid symbol. Lives can be refilled by finding more twisters and collectors. At the end of the round, you can collect your multipliers and your total win will be calculated.

FAQs
How does the Twisted Lab RotoGrid slot rotate?
First, you need to find the RotoGrid symbol. This can make the grid rotate by a quarter turn at a time. A RotoGrid circle can come with 1, 2, 3 or 4 charges, which means it can turn 1, 2, 3 or 4 times per turn, each presenting more chances to find winning symbols. The rotation of the grid will cause any beaker symbols to break, which leads to the next feature.
What do the beaker symbols do in the Twisted Lab RotoGrid slot?
In the base game, they’re wilds, substituting for regular symbols, although they also pay in their own right. When the beakers break, the contents ooze out, turning any other symbol touched into wilds. Some beakers also come with a win multiplier of between x2 and x100 that could apply to any of the touched symbols.
Does the Twisted Lab RotoGrid slot have any bonus games?
On top of these features, there are two bonus games, both triggered by the scatter symbol. Find 3 scatters to trigger 10 free spins, and find 4 to trigger a hold-and-win-style game where you have a minimum of 3 lives to try to collect twister symbols with multiplier values. There aren’t any regular paying symbols in this feature.
