A torchlit masked ball is the setting for Light Em Up, a 5 reel, 30 payline slot from Ainsworth. Look out here for the bonus feature which awards up to 15 free spins complete with stacked and multiplier wilds. Join the party from between 30p and an eye-watering £3,000 per spin.

The design in Light Em Up has an opulent feel – set against a purple backdrop and overlooked by a mysterious masked woman, the reels include lower value playing cards alongside fire rings, drums, lantern, swords and masks. Land a 5-of-a-kind combination of the swords or masks and you’ll win 10 times your total bet.

The masked woman is the wild – she doesn’t offer any pays but does replace everything bar the scatter. Expect to see plenty of the mystery guest when you trigger the Free Games feature. To do that, you’ll need to land 3, 4 or 5 of the Light Em Up logo scatter anywhere on the reels on the same spin. As well as a cash prize equal to 2, 10 or 100 times your total stake, you’ll also receive 10 free spins.

The free spins are played on a new set of reels. Above reels 2, 3 and 4 you’ll notice a collection of boxes – on each free spin, they can deliver a range of wild extras. These are awarded at random and can deliver a standard 1x wild, a 2x wild or a 3x wild. Better still are the expanding wilds- these fill up the whole of the reel in which they appear and also offer 1x, 2x or 3x boosts.

It’s possible to land wilds on multiple reels on the same free spin – the multipliers are combined too. So, for example, if you landed a 2x wild in conjunction with a 3x wild, the payout would rocket by 6x. These combinations offer some potentially massive winning chances. We’d put the variance in the medium range overall.

Like many Ainsworth slots, Light Em Up has the look and sound of a live casino slot. The visuals are solid enough but don’t rate among the best you’ll see. Likewise, the soundtrack, especially in the feature, which isn’t at all in keeping with the theme. That aside, the Free Games feature is a good one thanks to the presence of the stacked wild multipliers.

If the mysterious woman works her wild magic, Light Em Up can deliver some illuminating entertainment. If you like the mystery element, Play ‘N Go’s Jade Magician or Playtech’s Legacy of the Wild are recommended.
