The Lab

The Lab is a science-themed slot from Elk Studios that can be played on desktops and mobile devices from as little as 15p per spin.

Luckily, you don't need to be able to tell you Au's from your O2's to benefit from its powerful crystal molecules and element symbols, which can create an explosion of wins to the tune of 46,000 coins.

However, if you get sucked into The Lab's powerful vortex, you'll be creating free spins with five sliding reels and landing 2x multipliers with the X symbol. Plus, as always, you'll be able to put Elk Studios' handy betting strategies to good use to help you decide how much you should bet on each spin.

More about the Software Provider

Elk Studios is one of more exciting online slots developers that have surfaced in the past few years. Having created several smash hits with Sam on the Beach, Taco Brothers Saving Christmas, Hong Kong
Tower, Wild Toro, DJ Wild, and Champions Goal, the brand is currently the talk of the online casino world, with both players and industry experts waiting with bated breath to see what innovative slots come next.

Elk Studios takes a "mobile first" approach to its production of its slot games, meaning that if you choose to play slots like The Lab on your mobile phone or tablet, you can rest assured that each game is fully optimised both graphically and visually.

Appearance and Sound Effects

The Lab is set against a swirling red and purple vortex, which sucks in stars and other space matter every few seconds. And, although it's quite easy to become transfixed by it, you'll need to concentrate on the other areas of the reels if you want to start making some cash.

The five reels contain pink, blue, purple, and green crystal molecules which are the high-value paytable symbols, four elements (H2O, O2, Pt, and Au), an X, and the game logo. The highest paying combinations can be made with the green molecules.

The ambient instrumental music that forms the game's soundtrack is very pleasant to listen to as you spin the reels, and in our opinion, is reminiscent of "Crazy" by Seal.

Bonuses and Special Features

The game's logo – "The Lab" – is the wild symbol, and it's only used in the Free Spins Feature where it can substitute for any other symbol. The "X" scatter multiplies winning combinations by two for each visible scatter symbol.

The highlight of the game is the Sliding Reels Feature which is activated when "The Lab" logo lands on top of the swirling vortex on the centre spot of the second reel. The feature awards you ten free spins with all prizes doubled (and don't forget that you also have the wild symbol on hand to boost your winning potential even further). The Sliding Reels Feature adds to new reels to the far-left of the reel set, which consequently moves what were Reels 1, 2, and 3 to the far-right.

Don't forget that you also have the option to use the Booster, Leveller, and Jumper betting strategies which can be accessed via the Settings menu.


The Lab uses five reels, three rows of symbols, and fifteen paylines, and you can create wins from left to right across the reels. The game benefits from a high RTP (Return to Player Rate) of 96.30%, and the top jackpot is worth 46,000 coins.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls when played on mobile devices.

Our Verdict

The Lab is a beautifully executed online slot which relies on innovative features including Sliding Reels and scatter multipliers to deliver exceptional and exciting gameplay.
