Put on your white coat and step into The Lab, a 5 reel, 15 payline video slot from ELK Studios. This volatile, science-themed slot comes with the X Scatter feature where wins are boosted by 2x for every X-Scatter symbol that appears as well as a free spins bonus feature where all wins are doubled. Play from between 15p and £90 per spin.

Like other slots created by ELK Studios, The Lab is very easy on the eye. Set against a backdrop of a swirling vortex, the reels include a quartet of high-value crystal molecules. The green gem is the biggest payer, giving you 500 coins if you find 5 in a payline.

Rather than filling the rest of the reels with traditional playing card values, The Lab maintains the scientific theme and instead uses chemical symbols on the reels. Look out for H20 (water), 02 (oxygen), Pt (platinum) and Au (gold) symbols.

Look out too for the X-Scatter symbol. For every X-Scatter that appears on the reels any winning payline will be boosted by a 2x multiplier. The more scatters, the bigger the potential payout.

The Lab logo is the key to triggering the bonus feature – when it lands directly over the vortex on reel 2, row 2, the symbol will slide across the reels and trigger the Free Spins feature. Here you’ll be awarded an initial 10 free spins. You can add to these during the feature with extra free games added in chunks of ones and twos.

The Lab logo symbol will also act as a wild during the free spins, substituting for everything apart from the X-Scatter. The multipliers play out in the free spins round too – all winning paylines in the free spins round are subject to an automatic 2x multiplier and will be doubled.

You’ll also have the option to select one of a trio of automatic betting strategies which increase the level of your wagers depending on how the game has played out on the previous few spins. These strategies can also be used if you’re playing via autoplay.

Like many of the chemicals found in a science laboratory, The Lab can be volatile affair. The variance is on the medium to high side so expect some lean spells punctuated by occasional big wins. The most likely route to a big win is via the feature where the wild and multipliers can combine to impressive effect.

Great to look at and played out to a futuristic, sci-fi style soundtrack, The Lab is very easy to play. And with potential jackpots of up to 46,000 coins, the results can be pretty explosive too. It reminds me a little of NetEnt’s Starburst appearance wise though which isn’t a bad thing. However, I suggest you play ELK Studios’ Taco Brothers which is their best game in my opinion.
