Science themed online slot games aren’t exactly the most popular of games in the industry, but that is what makes gems like The Spin Lab by software manufacturer NextGen Gaming unique. First of all, we would like to just acknowledge the otherworldly feel of this offering; it comes equipped with superb visuals, a very fitting soundtrack, and an exciting setup. The backdrop is high tech, looking both simple and very sophisticated at the same time; and speaking of sophisticated, some of the symbols here look like they really did come straight out of a lab. There are molecules, DNA strands, and even a circuit board shaped like a cube.

As far as the game’s layout goes, there’s nothing particularly special here. It features the most conventional grid of 5 reels and 3 rows, and it comes with a total of 25 fixed paylines. Since they’re fixed, this means you will not have the ability to alter them in any way, and with that in mind, it should be noted that stakes here are rather on the steeper side; the minimum bet will set you back a pricy 40p per single spin, and the maximum amount you can wager on these reels is some £200 per spin.

Special Features


The weird glowing symbol displaying ungraspable colorful strands is the game’s Wild, and in addition to that, it’s also the highest paying symbol on these reels – with its help, players can potentially pocket up to 1,000 coins. But its wildly duties are more important than that even, as it will be able to replace any of the other symbols on the reels. In doing so the Wild can help complete winning sequences, thus boosting your winning chances.

It will also be able to land in any position on the reels, however, it cannot substitute for the Scatter.


The Scatter symbol will be able to trigger the game’s single yet very attractive bonus – the Freespins Feature. What makes it so attractive is that you get to create it yourself. You are initially given 5 freespins, and from then on you enter the Spin Lab to enhance them as your heart desires. There are three different extras that you can add to the freespins. More precisely, there are 3 rows of extras, each containing 3 different options, and you need to select one option from each row in order to form your feature – or you can always leave it up to the game to decide if you’re not in a choosing mood.

  1. Row 1 will offer you the option to have all of the higher value symbols turn into the same symbol. Its second option will make sure one of the higher value icons can appear stacked on the reels. Then there’s the option which will offer a random cash prize for every instance of a randomly selected high value icon.
  2. This brings us to Row 2, which concerns only the Wild symbol. Its first option will give you stacked Wilds throughout the feature. The second option will simply see extra Wilds appear on the reels. Then finally, the third option will add a random multiplier of between 2x and 10x to any Wild wins.
  3. Row 3 can offer you a 2x multiplier on all wins throughout the bonus round as its first option. As the second option you can choose for all wins to pay both ways. Last but not least, you can opt for an extra 5 freespins as your third choice. It should be noted that there is no possibility to retrigger the Freespins Feature.
