Our Verdict:

The sorceress theme that Crazy Tooth Studios has used in its Queen of the Crystal Rays slot game reminds us a little of IGT's Diamond Queen, except that the graphics are more clearly defined and the special features are more advanced.

We like how the Crystal Rays at the side of the reel set can turn ordinary wilds into potentially lucrative wild multipliers that are worth as much as x5. Plus, each time that you play Queen of the Crystal Rays, you could be lucky enough to win over 2,500 times your stake!


Queen of the Crystal Rays slot is compatible with iOS, Android, and Windows mobile phones and tablets. It uses 6 reels, 4 rows of symbols, and 50 fixed paylines (although more paylines are added in the bonus feature).

Central to the game is the blonde-haired sorceress known as the Queen of the Crystal Rays, and as well as acting as one of the most valuable symbols on the paytable, she can trigger the Crystal Rays Feature at random.

You can create winning combos from left-to-right only according to the diagram that's included at the bottom of the rules. Aside from the Queen, the symbols include pots of gold, treasure chests, magic crystals, and goblets.

You can alter your stake size by tapping the plus and minus arrows next to the box marked "Bet."

Wild Symbol:

The Queen of the Crystal Rays slot uses two different wild symbols. The first is a normal wild symbol which can replace all symbols (apart from bonus symbols) when it's possible to make a winning combination. The second is the x2 wild which doubles the value of any prizes that it helps you to secure.

Bonus Features:

Look out for the bonus symbol as you spin the reels of the Queen of the Crystal Rays slot game as, if 3 or more of them appear, you get to play the Free Spins Bonus. In the bonus feature, the Crystal Rays at the side of the playing area are activated, and as their laser beams begin to point across the reels, any wild symbols that lie in their path can be turned into wild multipliers worth up to x5.

The second special feature is called Crystal Rays, and each time that it's randomly awarded, another 25 paylines are added to the playing area.
