Twisted Lab RotoGrid Online Slot

Twisted Lab RotoGrid Online Slot Review

A mad scientist brings tentacles, eyeballs, and brains to the reels of the Twisted Lab RotoGrid slot from Hacksaw Gaming. These cartoonish symbols land on a 5x5 layout crossed by 19 paylines and if a RotoGrid symbol lands, a lab rat rotates the reels for the chance of further wins.

Oozing Beakers leak their valuable contents as the gird rotates, spilling wilds with multipliers across the game. Splash Ooze over more Ooze to combine their values. You can trigger 2 bonus features. In the standard Unleash The Ooze free games, there’s a greater chance to see Oozing Beakers, while the Twist Of The Twisted round is a respins game. Only blank spaces, RotoGrid symbols, Twisters with multipliers, and Collect symbols appear in this round which runs until Twisters run out of lives.

You can win as much as 15,000x your stake by the end of respins. Twisted Lab RotoGrid is a high volatility game with average returns of 96.30%. Experiment with the free version on this page, then play across desktop and mobile platforms for real wins at the best uk casinos online. 

How to Play the Twisted Lab RotoGrid Slot Game

The often-humorous action takes place in a pink and blue neon-lit laboratory, where the mad Mr. Melker and his pet, Pat the Rat, stand to the sides of the reels. The glowing symbols include the brain, an egg, mushroom, vampire teeth, and other strange ingredients needed to concoct winning spins. The cartoon style suits the mad scientist topic and there are plenty of enjoyable animations as the reels spin.

Tap plus or minus tabs above and below the main spin button and you can easily pick from the bet range of 0.10 to 100.00 on each spin. You win whenever 3, 4, or 5 matched symbols land across any of the 19 lines that run from the left reel, and the 3 lines button opens a paytable which reveals the value of each at your current bet. The lowest value feather is worth up to 0.5x your stake, with the valuable brain paying a maximum of 5x. There are extra details on features such as rotating reels and Oozing Beakers on the table, so it’s worth a readthrough before you stake real money. 

Options from the Twisted Lab RotoGrid slot include buying into bonus features with one-off bets, Autoplay, and Quick Spin features, although these are not available from the UK. Anyone can enjoy the exact same gameplay and features on desktop platforms, iOS, Android, or Windows mobiles, including when using the best casino sign up offers. 

Free Spins & Other Twisted Lab RotoGrid Slot Features

The 8-sided RotoGrid symbol triggers the signature feature on each appearance. It holds from 1 to 4 Charges, which equals the number of times the rat will turn the whole grid by 90 degrees clockwise. Once any wins are paid, the grid turns, which has the effect of lining new symbols across the 19 paylines. If this leads to a new win, you get paid, but even if it doesn’t form a winning combination the reels still rotate as many times as the RotoGrid symbol allows.

Oozing Beakers help at any time. These colourful bottles of potion spill their contents when tipped over, which then ooze down to the bottom of the reels, turning all symbols they cover into wilds that substitute for others. Different Oozing Beakers hold different multipliers that apply to any wins they help to create –

• Purple Beakers – These don’t hold multipliers.
• Blue Beakers – These hold random multipliers of 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, or 100x.
• Pink Beakers – These hold multiplying multipliers of either x2, x3, x4, x5, or x10 that apply to any Blue Beaker values if they ooze over them.

Any multipliers overlaying an already existing value as the reels rotate will see their values combine into a green ooze. 

Three scatter symbols award the Unleash the Ooze free spins, where there’s a greater chance of landing RotoGrid symbols and Oozing Beakers.

If 4 scatters land at once, you enter the Twist of the Twisted bonus round. It’s a respins feature where you get 3 spins with blue or pink Twisters, RotoGrid, and Collect symbols or blanks, and any active symbols reset the counter. 

Twisters hold values of 1x, 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 1000x on each of the 4 sides and whatever is on the top side is the current multiplier. Collect symbols gather all values in view and RotoGrid symbols turn Twisters to change the active multiplier. This continues until you have 3 spins in a row with just blanks after which you grab the total multiplier values built up throughout the round.

Twisted Lab RotoGrid Slot Maximum Wins, Volatility, & Average Returns

There’s up to 15,000x your bet available in the Twist of the Twisted feature, or 1,500,000.00 if you have the maximum 100.00 in play when it triggers. 

It’s a high volatility game with average returns of 96.30%, so you’ll tend to see fewer wins than lower variance games but comparatively high value prizes.

Our Twisted Lab RotoGrid Slot Rating

There’s lots of science behind what makes the Twisted Lab RotoGrid slot so appealing. Hacksaw Gaming’s’ experiment with the RotoGrid mechanism is a resounding success that can give you up to 4 wins in quick succession as symbol reorientate across the game. It won’t always lead to further wins though. 

Once Ooze starts to spill down the grid, it makes wins easier by substituting for other symbols, and there’s the potential for huge multipliers, particularly if it oozes over any already on the reels. Free spins with extra RotoGrid and Oozing Beakers can lead to big wins, but it’s the Twist of the Twisted feature you really want, as this is where the 15,000x maximum prize becomes a possibility. 

Colourful cartoon symbols plus animations from Mr. Melker and Pat the Rat add to the charms. Join them as you play the Twisted Lab RotoGrid online slot at the best slot sites.
