How to play The Spin Lab mobile slot

The mad scientist of games, build your own free spin bonus out of a possible 27 combinations in The Spin Lab slot.

This 25 payline 5 reel video slot requires a little experience, though this isn’t actually as complicated a slot game as you might first think.

In fact, despite the promise of 27 different free spins and a top win of 50,000 in cash, The Spin Lab mobile slot is actually ridiculously simple.

A little how Piggy Riches Megaways slot appears complicated because of all the pretty graphics, but ultimately isn’t.

It’s basically a game with wilds, scatters and free spins. And that’s it.

Straight into the free spins

Still, despite the simplicity, this is one of theNextGen slots that is not for the faint of heart.

As a fairly mid to high variance slot, you’ll have to wait a while to get the truly big wins, and then only once you catch the free spins.

And only if you choose the right free spin combination, out of a possible 27 choices.

Which is the right one, you ask? Excellent question. We lay out all the possible choices in the feature section below, but we suspect it’s just down to how the machine is feeling.

If you are feeling really lazy, just do the auto pick – you’ve got as good a chance as any to get decent wins.

The Spin Lab slot has a full history of best results

The good news is that NextGen have made it easier to see which combinations work best. Mostly you’ll get about 20x your bet as an average, with obviously more being the aim.

Though our best results seem to be with the stacked symbols, extra wilds and paying both ways. However, we suspect the big wins come if you pick the wild with multipliers and the 2x multiplier on all wins.

But that’s also the best way to walk away with little to nothing.

Open, spacious and futuristic

The Spin Lab slot isn’t the best NextGen machine we’ve ever played. That honour probably goes to 300 Shields or Merlin’s Magic Respins.

But having played our fair share of mobile slots, we won’t lie that we were taken in by the fact that not only could you win big, but as an experienced player, you get a degree of choice and control.

Even if that control is mostly for show.

Bonus Features

Wilds: The... euh... multicoloured... DNA... sequence...? The symbol with 'wild' is wild obviously. It replaces all other symbols except scatter.

Scatters and Free Spins: Get three or more molecule scatters anywhere on the reels and you'll trigger 5 free spins.

Then you'll get to pick one symbol from each of the three rows. There are a total of 27 different combinations, and you can check your history of how much you've won on each of your choices.

Row 1:

  • Symbols the same: the cube, molecule, atom or DNA symbol is selected at random and then they all become that one symbol. Leading to more of one of the high paying symbols.
  • Symbol stacked: the cube, molecule, atom or DNA symbol is selected at random and will come stacked.
  • Symbol prizes: the cube, molecule, atom or DNA symbol is selected and then every time one shows up during the free spins and give you a prize of 500, 250, 200, 150, 100, 50 or 25.

Row 2:

  • Stacked wilds: wilds come stacked.
  • Extra wilds: more wilds are added to the reels.
  • Wild multipliers: any time a wild shows up and is used for a win, you will get a random multiplier of 2x, 3x, 4x, 5x, or 10x.

Row 3:

  • All wins multiplied: all wins during the free spins have a 2x multiplier.
  • Pays both ways: winning paylines pay from right to left and left to right.
  • Extra 5 free games: increases your free spins rounds from 5 to 10.

The Spin Lab Review Conclusion

With some good wins and a fairly unique free spin bonus feature, The Spin Lab mobile slot will appeal to those of us who like control and take responsibility for our choice.

It's also for the more advanced player, who knows how to budget well, and doesn't mind thinking a little about their game play.

If that sounds like too much effort, the Titan Storm slot has just as many good wins, but is a little easier on the head.
