Introduction to the Mad Scientist Theme
Do you think, in another life, some of the boffins making a living crafting online slots would be poring over forbidden tomes in search of esoteric knowledge to conduct experiments that threaten the fabric of the very universe? Maybe not, but the ‘mad scientist’ trope is a popular one when it comes to slot design, and slot maker Hacksaw Gaming has come up with an eccentric example. The title is Twisted Lab RotoGrid, and it has turned out to be an ideal place for the studio to combine some of its favourite things, namely, quirky characters, spreading wild multipliers, and a fiendish hold ‘n win/respin round.
Setting and Characters
A twisted lab well and truly is the setting for the game. In this cracked world, players are introduced to Mr. Melker and his helper Pat the Rat, and the mix of Hacksaw Gaming’s past endeavours on display in Twisted Lab RotoGrid is nicely summed up in verse: “Five drops of Canny, Three spills of Crew, Slight hint of madness, Yummy Hacksaw brew!” You get the impression the team had a laugh or two when it set about making Twisted Lab RotoGrid, employing the neon on dark punk design it has used to excellent effect in the past in games like Chaos Crew 2 and to excellently twisted effect here.
Rotating Gaming Panel
If you get motion sickness, then Twisted Lab RotoGrid’s rotating 5×5 gaming panel might not be the best thing to stare at for long periods of time. If motion isn’t an issue, then keeping an eye glued to its 19 paylines is one way of tracking winning combinations, no matter the movement. Available in various RTP configurations, 96.3% is the maximum return value, and 4 out of 5, or medium-high, is the volatility rating. Bets of 10c to $/€100 are up for selection, as are five bonus buy choices.
Pay Symbols and Wilds
Twisted Lab RotoGrid’s pay symbols consist of 8 different objects, kinda fitting, kinda random. They are a feather, leaves, an egg, a mushroom, a piece of tentacle, an eyeball, teeth, and a brain, paying 0.5 to 5 times the bet for a five-of-a-kind winning combination. Beaker symbols are wild, more on them in a moment, meaning they can substitute for any regular pay symbol fada888 and are worth 10x the bet for 5 OAK.
RotoGrid Symbol
First, let’s introduce the new RotoGrid symbol, which may land charged with 1 to 4 ninety-degree clockwise rotations. Each charge causes the whole grid to rotate by 90 degrees, creating additional opportunities to achieve payline wins. Wins from the initial drop are awarded before the RotoGrid activates.
Oozing Beakers
When the RotoGrid rotates the grid, any Oozing Beakers on the reels break and spill their contents to the bottom of the grid. All positions covered by Ooze become wild, substituting for all paying symbols. Purple Oozing Beakers do not contain multiplier values. The possible values for Blue Oozing Beakers are additive values of x2 to x100. The possible values for Pink Oozing Beakers are multiplying values of x2 to x10. If Ooze covers previous Ooze, the multiplier values are added together and applied to all Oozing positions in the reel. If Blue Ooze combines with Pink Ooze, their multipliers are added together, and the resulting Green Ooze multiplier will become multiplying. If Blue or Pink Ooze is combined with Purple Ooze, the multiplier from the Pink or Blue Ooze is applied to the whole combined Ooze area on that reel.
Unleash the Ooze! Bonus Feature
This feature is activated in the base game by landing 3 FS scatter symbols. Starting with 10 free spins, during this bonus, there is an increased chance of landing RotoGrid symbols, FS symbols, and Oozing Beakers.
The Twist of the Twisted! Bonus Feature
This feature is activated by landing 4 FS scatter symbols in the base game, awarding 3 initial lives. For this bonus, the game transforms so only Blue Twisters, Pink Twisters, Collect symbols, RotoGrid symbols, and non-paying symbols appear. Four fada888 multiplier values are displayed on each Twister. The value shown at the top is the current value of the multiplier. When the grid rotates, the value that moves to the top of the symbol becomes the new current value. Possible values for the Blue Twister are 1x to 1,000x. The possible values for the Pink Twister are 1x to 1,000x, or x2 to x10.
