Hacksaw Gaming released Twisted Lab RotoGrid on June 27 2024. The video slot is set in a twisted lab well hosted by Mr Melker and Pat the Rat. 

In this review, you will learn about the game setup and bonus features.

Game setup

Once you start the game, you have 5 reels and 5 rows to land winning combinations on 19 paylines. The default RTP is 96.30%.

The other RTPs are 94.20%, 92.18% and 88.23%.

You need a minimum bet of 0.10 or a maximum bet of 100 to stand a chance at the maximum win of 15000x. The slot is played on a high volatility. 

For combinations, you have 8 symbols: an egg, leaves, feather, mushroom, tentacle, eyeball, teeth and brain. The regards for landing 5 matching symbols is 0.5x to 5x. 

You can also land wilds which are the beaker symbol. 5 matching wilds reward you with 10x. 

Bonus features 

Oozing beakers

Oozing beakers break and spill to the bottom of the grid once the RotoGrid rotates the grid. Any position that is oozed becomes wild which replaces all paying symbols. 

The three ooze colours have different features:

• Purple has no multiplier

• Pink carries multipliers from 2x to 10x

• Blue carries multipliers from 2x to 100x 

When the ooze spills on the previous ooze, the multipliers are added and applied to all positions with the ooze. Blue and pink ooze combined turn green and add the multipliers while blue/pink ooze combined with purple applies the multipliers from blue/pink to the combined ooze area. 

Unleash the ooze

Landing 3 FS scatters activates the feature and rewards you with 10 Free Spins. It increases the chance of landing 3 symbols; the RotoGrid symbol, FS symbols and oozing beakers. 

The twist of the twisted!

Landing 4 FS scatters in the base activates the feature which starts with 3 initial lives. During the round, only 5 symbols appear which are:

• Blue Twisters

• Pink Twisters

• Collect Symbols

• RotoGrid Symbols

• Non-pay Symbols

Each Twister carries four multipliers. The Blue Twister carries multipliers 1x to 1000x and the Pink Twister 1x to 1000x or 2x to 10x. 

When a Collector lands, it collects the multiplier values of all Twisters on the grid. The Twisters stay on the grid until the round ends or they are collected. 

When new Twisters or Collector symbols land, the lives reset to 3. The feature ends when the Twister and Collector values are added or multiplied.

Bonus buy

Skip straight to the bonus round with this feature by placing:

• 3x the bet for Bonus Hunt Feature Spins

• 50x the bet for RotoGrid Feature Spins

• 75x the bet for Oozing RotoGrid Feature Spins

• 100x the bet for Unleash the Ooze 

• 200x the bet for Twist of the Twisted 

Verdict 

If you enjoy quirky slots, this is the slot for you. You will especially enjoy the bonus features such as the Unleash the Ooze feature which turns symbols wild and adds multipliers.
