How to Play
The playing field consisting of 6 reels in 4 rows provides up to 50 lines that pay both ways. Combinations are created from 3 to 6 of a kind symbols on adjacent reels. Wild symbols help to create combinations by replacing regular symbols and there are also Wild Multipliers, which we will talk about a bit later. The betting range starts at €0.2 and you can bet up to €50 per spin.
To start this mystery journey all you need is:
- Open Queen of the Crystal Rays at your chosen casino
- Look at the possible payouts in the paytable
- Read the rules of bonus features
- Choose a bet from the range of €0.2–€50
- Press the spin button to set the reels in motion!
Queen of the Crystal Rays RTP and Volatility
Medium volatility and 96.7% RTP are a good combination for high wins.
Crazy Tooth Studio has made a pretty well-balanced math model for this slot so you will be dealing with medium risk here. This means that good things like prize combinations and bonus features will happen more often than in high-risk games and sometimes you can get really big prizes. The theoretical return (RTP) stands firmly at 96.7% which is above the industry average.
Theme
The game has a fantasy theme and it's obvious from the title that it has a queen and crystals. In the background, there is a wall with patterns that sometimes changes its color and in the middle, there is a large playing field filled with crystals, chests, prisms and other symbols. Queen of the Crystal Rays is like a slot that is at least 10 years old as players these days expect much more creative designs and better graphics.
The queen, chest, bowl and plate filled with gold are premium symbols, while the low-paying symbols are 4 gems. There is also the inscription "Wild" which is the Wild symbol, 2x which is the Wild Multiplier, the inscription "Bonus" which is the Scatter symbol and the prism about which we will talk below.

Mobile Compatibility

Yeah, this slot machine really looks like it is at least 10 years old but it was made using modern JS and HTML5 technologies, which makes it well compatible with all modern mobile devices. You can take this mystical adventure with gems and prisms anytime, anywhere, just launch Queen of the Crystal Rays from your smartphone or tablet!
About Crazy Tooth Studio
This gem-themed slot was created by Crazy Tooth Studio, a provider that creates top-notch casino games with unique gameplay. Crazy Tooth Studio was founded in 2011 by Ben Hoffman, who gained vast experience in the online gambling industry while working at IGT. The company's unusual but memorable company name was inspired by Hoffman's dog and its protruding tooth.
Bonus Rounds & Free Spins
Wild Symbols and Wild Multipliers
Wild symbols are an important part of the game. They replace regular symbols to give you much more combos in the long run. There are also 2x Wild Multipliers here. They double the payout for a combination when they participate in it.
Free Spins
To activate the Free Spins feature, you only need to land 3 or more Scatters (inscriptions "Bonus") anywhere in view. Four free spins will be awarded. At the start, the playing field is populated with credit values that can be won. Credit awards are multiplied by the bonus bet multiplier. In each round, Crystal Rays initiate and credit values along the path of the crystal rays are awarded. Credit values may be multiplied by up to 5 times.

Crystal Rays
Crystal Rays is a random bonus feature that can be activated in the base game. It triggers a large playing area and additional 25 lines – this is how you can activate the maximum possible 50 lines! This exciting feature will also reflect rays with the help of prisms and then give you Wild symbols or Wild Multipliers on their way.

Overall Rating
Queen of the Crystal Rays looks like it's a bit outdated but if you digest its design, you'll notice that there's some decent gameplay underneath, full of fun features and massive prizes. The game has an RTP higher than average, a relatively good max win potential and a unique set of bonus features that might definitely convince some players to give it a try. You know, we would love to see this slot get a "second chance", a sequel with a better design that could keep the good math and bonuses of the original.

The upside is in RAY feature when board grows to 50 symbols + wilds appear. Triggering it is a good motivation. I was lucky to trigger it 4 times in 100 spins.
Actually, it’s FS round that was harder to trigger. I was kinda annoyed by low-quality “close but no cigar” trolling with 2 scatters.
Finally, after 150 spins I triggered FS! A fun round with guaranteed wins. And those wins can be really big. In my case It was ok.
