About the Game

Cosmic Crystals slots online have a 5 reel, 3 line, 50 fixed payline format.

There are the usual playing cards – 10, Jack, Queen, King and Ace – which are the lower score symbols, and pink, purple, blue, green and yellow crystals which score more progressively so yellow scores higher than pink. These coloured crystals might be rose quartz, amethyst, agate, malachite and amber but since they come from outer space, your guess is as good as mine.

This game has an amazing unique feature – if you don’t score a win when you spin the first time, you get an automatic free respin until you do!  However, be sure to check the paytable as even although you can score a win each spin, the payouts might not be as high as you find in other online slots casino games.

The Verdict

Cosmic Crystals online slots is a great little game. It’s slick and futuristic in design and you are guaranteed to win something with the game’s ‘spin until you win’ free spin feature. However, look carefully at the paytable to work out what you can win. The regular cards only pay good returns if you spin 5 of them on a line.  However, if you like the experience of winning often no matter how little, Cosmic Crystals is going to deliver.
