Halfway through 2024, the Twisted Lab slot first made its way onto the casino market, coming with a whole range of innovative elements thanks to developers Hacksaw Gaming. Not only did this title feature a theme inspired by mad scientists and their alchemical experimentations, but also a series of game mechanics that are rarely found elsewhere in other online slots. From rotating playgrids and collect mechanics, all the way to multiplier symbols, there are so many unique layers to this Twisted Lab slot.

Beginning with the general layout of the Twisted Lab slot, Hacksaw Gaming have opted to present a black 5x5 playtable in the middle of the screen. Although this layout is the standard for Slingo games, there are paylines still featured here, 19 to be exact. A metal contraption surrounds the playtable, all whilst the luminous, melting Twisted Lab logo can be seen off to the left of play, located directly above a mad scientist holding test tubes.

A giant lab filled with glowing pods, radioactive silos and twisting pipe work can be seen in the backdrop, all of which is backed by pink and purple fumes. In the foreground, a mouse with cybernetic enhancements can be seen perched atop a futuristic computer, with all of the game information and buttons being located beneath. Although Alchemy Fortunes and the John Hunter and Galileos Secrets slot feature science-inspired themes, the futuristic style of this Twisted Lab slot helps it to differentiate itself.

When moving onto the set of base game symbols, it will be refreshing to many that this Twisted Lab slot features no paytable inclusions inspired by live casino games. Instead, the lower-valued symbols are different ingredients and items likely involved in the mad scientist’s experiments, whilst the higher-valued ones are different coloured test tubes.

Lower Value Symbols:

Mushroom

Egg

Leaf

Feather

Medium Value Symbols:

Teeth

Eyeball

Tentacle

Brain

Higher Value Symbols:

Pink Test Tube

Blue Test Tube

Purple Test Tube

Besides these base game symbols, there are also purple fish, cat skull, bird skull and apple symbols, with these not actually having any value and essentially acting as blockers. For bonus symbols, though, the Twisted Lab slot features a number of coloured twisters, a rotating arrow and an oozing ‘FS’ scatter, with the aforementioned test tubes potentially displaying multipliers too.

The most nuanced and innovative addition to this Twisted Lab slot is the RotoGrid mechanic. If a rotating arrow symbol lands anywhere across the reels, it will randomly have between 1 and 4 charges. These charges cause the entire playtable to rotate 90 degrees clockwise each time, essentially re-ordering the reels and allowing the paylines to work across new symbols in the same spin. Even with there being Megaways slots out there, this changing reelset system is completely new and brings a whole other dynamic to the Twisted Lab slot.

As we have just briefly touched upon, the coloured test tubes in the Twisted Lab slot could feature multipliers attached to them as well. If these are on the playtable whenever the playgrid may begin to rotate, this will see the test tubes break and the multipliers they have displayed on them collected. The respective multiplier values of these test tubes could be as follows:

Pink Test Tubes could have multipliers of 2x, 3x, 4x, 5x or 10x.

Blue Test Tubes could have multipliers of 2x, 3x, 4x, 5x, 10x, 15x, 25x, 50x or 100x.

Purple Test Tubes do not actually contain multipliers but instead spill their coloured contaminants onto the reels.

If the purple test tubes see their fluids spill onto other test tubes in view, this could potentially cause their multipliers to be combined!

Should a player land 4 or more of the oozing ‘FS’ scatters in the same spin, this could trigger the ‘Twist of the Twisted’ bonus round. This is where the coloured twister symbols are introduced to the Twisted Lab slot, with blue ones having multipliers between 1x and 1000x and the purple ones being valued between 1x and 10x. There is also a green twister; however, this acts as a collector. Like the bonus rounds found in 3 Pyramids of Gold Hold & Win, players are given 3 respins in which only these twisters and the previously mentioned blank symbols could land. If any twisters land, they lock in place and reset the respin total. Should a green twister appear, though, this instead collects all values on screen before becoming sticky.

Despite having a gameplay blueprint and theme unlike many other titles at BoyleSports Games, the Twisted Lab slot still has a similarity with all releases on site. This is in relation to its mobile optimisation, as Hacksaw Gaming has made sure this game preserves every bit of quality across different device types.

Based on the RotoGrid mechanic alone, this Twisted Lab slot is a truly unique addition to the world of iGaming. The nuanced nature of this game is elevated further when also factoring in the mad scientist-centred theme, the multiplier bonus round and the unique test tube symbols, all of which highlight Hacksaw’s creativity.

If you are impressed by the level of innovation on show in the Twisted Lab slot, Le Bandit and the Spinman slot are also products of Hacksaw Gaming.
