The Twisted Lab Slot Game

In Hacksaw Gaming’s own words, it’s time to take yourself on a truly twisted tale to discover the secrets to the perfect Hacksaw recipe. So, are you ready to don your lab coat and get twisty?

There’s no denying that the visuals in Twisted Lab are appealing. But be careful not to be confused by the plenty of color gracing the background.

The slot happens inside a well-equipped laboratory, and you’ll see Mr Melker and Pat the Rat flanking the reels, looking eccentric. While Mr Melker has a transparent glass covering his brain matter, Pat the Rat looks somewhat robotic.

However, an upbeat melody complements the visuals contrary to an ominous tune, which you’d expect in such themes. To bring yourself closer to home, I recommend exploring the slot’s free demo linked on this GoodLuckMate page!

Symbols and Payouts

The scenes on-screen take a rather sinister sight of brains, jaws, tentacles, and eyes, among others. I wonder if the duo are practising science or witchery.

Argh! Scratch that; I should have been done with the theme by now and focusing on what the symbols offer. As seen from the paytable, there are 8 regulars and at least 5 specials.

Only the regular symbols can complete winning combinations, as displayed in the prize table. For the record, you win when you match identical symbols along a predefined win line from the leftmost column towards the right.

The Feather and Leaf introduce you to the Twisted Lab paytable, and they pay 0.1-0.5x the bet for 3+ OAK. Then, the Egg and Mushroom are worth 0.2-1x stake for 3+ OAK, too!

On the contrary, the high-paying symbols include the Tentacle, Eyeball, Jaws, and Brain Matter. As sinister as they look, they pay slightly better at 0.5-2x for the first two and 1-5x stake for the latter two when 3+ OAK simultaneously land.

Three Beakers shaped as Triangular, Circular, or Square pay the most valuable win, worth 10x stake for five of the same! They also substitute for all the paytable symbols.

Twisted Lab Slot Bonus Features

This game introduces a new RotoGrid engine and other exciting features, including free spins, expanding wilds, and multipliers!

RotoGrid™

The RotoGrid symbol can land on the Twisted Lab reels charged with one to four 90° clockwise rotations. Each charge makes the entire grid rotate by 90 degrees, creating more chances of winning.

Oozing Beakers

When the RotoGrid triggers the gameboard to rotate, any Oozing Beakers on-screen shatter and spill their content to the grid’s bottom. In other words, they are expanding wilds that cover the positions touched by the ooze and substitute for all the paytable symbols.

Although the Purple Oozing Beaker doesn’t contain multipliers, the Blue and Pink ones do, respectively, have 2-100x and 2-10x multipliers.

If an Ooze spills and covers a previous Ooze, the multipliers will be added before being applied to all the Oozing positions on that reel.

If the Blue and Pink Oozes combine, their multipliers will be added, and the produced Green Ooze multiplier will be effective. However, if the Blue or Pink Ooze combine with the Purple Ooze, the Pink or Blue Oooze multipliers will be applied to that column's entire combined Oooze region.

Unleash the Ooze!

Land 3 FS scatters to start this feature with 10 free spins. You’ll have better chances of landing the RotoGrid, FS scatters, and Oozing Beakers throughout the bonus.

The Twist of the Twisted!

Meanwhile, landing 4 FS scatters in the base game trigger triggers this bonus with 3 lives. Only the Pink and Blue Twisters, RotoGrid, Collect, and non-winning symbols will appear during this bonus.

Each Twister displays four multipliers, but when the gameboard rotates, the value at the top becomes the new current value:

  • Blue Twister - 1-1000x multipliers.
  • Pink Twister - 1-10x multipliers.

The Blue Twisters rotate with the grid when the RotoGrid symbol lands. But the Pink Twisters rotate on every new free spin and another time with the gameboard when the RotoGrid symbol appears.

A Collector may land throughout the feature, activating at the end of the current spin. Once enabled, it collects all on-screen Twister multiplier values. All Twisters stay sticky until they are collected or at the end of the feature.   

This Twisted Lab bonus has 3 resetting lives that refill whenever Collectors or Twisters land. However, the feature ends when all lives end. If it so happens, the current Collector and Twister are multiplied or added, depending on the symbol’s value.

The addition or multiplication happens from top to bottom, one reel at a time from left to right. If the initial symbol value is a multiplying multiplier, it will be assumed as an adding multiplier instead. The resulting value will be multiplied by your stake!

Bonus Buy

Use one of five bonus options in the “Bonus Buy” option to trigger it instantly. Their prices range between 3x and 200x bet, and their RTPs vary, as displayed on the information page. 

How to Win at Twisted Lab Slot   

This game's features have many twists and turns, but its overall playing process is simplistic. You can confirm through the free demo offered on this GoodLuckMate website!

First, it has a popular 5x5 grid setup with 19 paylines. So, you win when matching symbols appear sequentially on any valid win line, starting from the leftmost reel to the right.

You can bet between €0.10 and €100 in this Twisted Lab slot.

Once done (using the +/− buttons), hit the larger circle to play a single spin. Otherwise, you can use the smaller circle to access the Autoplay function and select several customizable auto-spins.

The three-lined button is another essential function, which reveals the game’s paytable and rules.

Twisted Lab Slot RTP & Volatility

Beware of variable RTPs, ranging between 88.23% and 96.30%, when searching for an online casino from which to gamble this slot. Meanwhile, it has medium to high volatility and a 15,000x bet win cap!    

The Final Thoughts

It’s not typical to encounter a Hacksaw Gaming slot with plenty of bonus features. But I guess an exception isn't bad occasionally, such as what you’ll find in this video slot. I'm not saying that their other games are bad, but with more features come more winning opportunities. Right?

However, I’m afraid not all players may grasp the features in Twisted Lab right off the bat. That’s why GoodLuckMate has provided the demo for free to help you practise the game until you’re comfortable gambling with your dough.

To answer my earlier question about whether Mr Melker and Pat the Rat can outdo other quirky duos, they can! I mean, the team has put up a series of mechanics, including the RotoGrid engine, which can award up to a lucrative 15,000x bet! However, you’d have to limit your bets to avoid exposing yourself to high risk.
