Join an intergalactic space party in Cosmic Disco, a supremely silly video slot from Playtech. It’s a 5 reel, 20 payline game that comes with a bonus round that awards 8 free spins with sticky wilds then another 8 where the locked wilds remain in more place and more wilds are added to reel 5. Blast off from 20p to £500 per spin.

Imagine that a gang of extra-terrestrial chums are getting together for a birthday party and you’ll have an idea of what to expect here. Set against a deep space backdrop, the reels include amoeba-like playing card symbols, cocktails and a trio of aliens.

The best of these is the 1-eyed creature who’ll get you 150, 300 or 1,000 coins if you land 3, 4 or 5 on a payline. The flying saucer is the wild. It doesn’t offer any payouts but does replace everything apart from the scatter when it hits on reels 2, 3, 4 and 5.

The glitterball is that scatter – when it hits on reels 1, 3 and 5 on the same spin you’ll trigger the Free Games feature. Here you’ll be awarded an initial set of 8 free spins. Any wilds that land on the middle 3 reels during these free spins will become sticky.

Once the initial 8 free spins are completed, the wilds are locked in place. You’ll then get another 8 free spins. There aren’t any new wilds on the middle 3 reels this time but extra wilds are added to reel 5. This can lead to wilds across 4 reels for huge wins.

As you’d expect given the theme, the visuals are done cartoon style – they’re not the greatest you’ll see but are a good match for the madcap theme. The theme in Cosmic Disco is indeed very silly but these aliens can deliver some serious action, especially in the feature round.

It’s not the easiest to trigger but the decent number of free spins on offer combined with the sticky wilds can make it well worth the wait. We managed to win over 850 times our stake after a landing a nice combination of wilds. If you like the space theme, Playtech’s Space Invaders and NetEnt’s Space Wars are recommended.
