Queen of the Crystal Rays is a newest video slot which was developed by Crazy Tooth Studio, as an exclusive title which will be available at Microgaming casinos. The game has an unusual setup and several good features, so there is certainly enough there to get the player’s interest.

This is a game with a setup which offers 6x3 reels, along with a maximum of 50 active lines. Features will include expanding reels, wilds and free spins, so there are several ways to boost winnings. Thanks to the game’s combinations and features, the RTP gets to 96.70%, while the highest rewards offered by the game can reach $129,872.

Betting and Prizes

With a minimum bet of $0.20, Queen of the Crystal Rays can end up asking for as much as $50 per spin. In exchange, you get a system which uses the Any Adjacent Pays system, and a maximum of 50 active lines.

After many test spins simulated (10 billion rounds), Crazy Tooth reached the conclusion that the game will pay up to 2597.45X total stake, which just so happens to mean a top value of $129,872.

Expect this game to have Medium volatility, which provides players with a certain balance, between high risk/high reward and low risk/low reward scenarios. RTP wise it’s doing quite well, being set to 96.70%.

Queen of the Crystal Rays Slot Features

The game’s way of getting you wins is through a system called Any Adjacent Pays, where symbols of the same type give you rewards if they line up on adjacent reels.

You will find quite a few stacked symbols inside, and the game will often create multiple wins at the same time, when it does manage to line up the required symbols to get you paid.

Wilds are also going to be part of the game, and they are substitutes which will help you create a lot more wins in the long run. Variants with 2x multipliers are present, and they can help double the value of winning combinations.

As for the free spins, this feature comes with a doubled number of paylines, and the potential patyou doubles as well, as a result. To actually get into the feature, you need 3+ bonus symbols scattered in view. A total of four stages allow you to advance through them, and there is going to be a Crystal Rays feature active as well.

Crystal Rays is also the name of a random feature, which you can get in the base game. It will give you a bigger game area and an additional 25 lines, which is how you get to the maximum of 50 lines possible. It will also reflect rays through crystals, and then it will give you wilds on their path.

Theme & Design

The slot’s theme is fantasy related, and it features a queen and crystals, obviously. The images you see inside will give you logos, plus the Queen, goblets, treasure chests and the different types of crystals (red, green pink). I’d call the game’s design average at best. It looks like a slot that’s at least a decade old, as these days players expect much better graphics.


Queen of the Crystal Rays might not have the best graphics around, but its medium volatility, high-enough rewards, excellent RTP and unique mix of features, could definitely convince some players to try it out.
