A new fantasy themed slot machine is set to be released, it will be offered by Microgaming casinos, and it will originate from a small developer called Crazy Tooth. They’re providers of exclusive content for Microgaming, a type of partnership that brought us several good games lately.

Queen of the Crystal Rays is not your typical slot machine, at least gameplay wise. It offers 6x3 reels and a system with 50 lines, though they also mention using the Any Adjacent Pays system. As big features of theirs, the list includes stacked symbols, wilds and free spins. Described as a game with Medium volatility, Queen of the Crystal Rays offers wins of up to 2597.45x total stake, which could mean over $129,000.

Betting and Prizes

Even with the 50 active lines which are at your disposal, this game only needs $0.20 to get it all started. At the other end, there are bets of up to $50 per spin that can be placed, which would send $1 to each line.

The developer announced that after simulating over 10 billion games, this slot machine had a top payout of 2597.45x total bet to pay. Turning the game’s maximum bet into a cash prize, would mean that you could get at most $129,872 this way.

They’ve announced that the slot has Medium volatility, so don’t expect for easy wins to come your way, but you shouldn’t be seeing long periods of time without prizes either. I’d consider its RTP, of 96.70%, another element in the game’s favor.

Queen of the Crystal Rays Slot Features

A game which has only stacked symbols among its regulars, it tends to create multiple wins at a time, and that’s a good thing, even though it takes the volatility up a bit.

There will be wilds inside, and they will be contributors to new winning combinations when they line-up with the right regular symbols. There is a 2x wild here, which helps boost wins as well, doubling their value if it’s a contributor to their combinations.

Crystal Rays is a random feature, which could be triggered during regular spins. It will give you 25 extra lines to form combinations on, which is how you get to the total of 50 paylines. Rays will pass through crystals and will bounce around the reels. As the spin ends, the path taken by the ray is turned into regular or multiplier wilds.

The free spins are also present, and the game will trigger them with a doubled number of lines for you to take advantage of. It’s a scatter that will get you this feature, at least 3 such symbols being needed at the same time in view. There are Crystal Rays active for each round, along with four stages that you can get through.

Theme & Design

Queen of the Crystal Rays is telling us a story, but it does it with dated graphics. The fantasy connection is unmistakable, and the game features all the right symbols for this. The Queen is present inside, as are images of goblets, treasure chests, logos and various colorful crystals (low value icons). As I said, it’s not a great design, certainly not better than what we’ve seen from Crazy Tooth Studio/Microgaming so far.


Queen of the Crystal Rays is exciting enough to play, mainly thanks to the features that have been implemented inside, or the high RTP it promises. If you enjoy slots with great graphics, you will likely be disappointed in this game though.
