RTP and Volatility

9.7/10

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

9.6/10

Queen of the Crystal Rays

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.

Bonus Rounds & Free Spins

9/10

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.

overall rating:
8.9/10

Queen of the Crystal Rays looks like it's a bit outdated but if you digest its design, you'll notice that there's some decent gameplay underneath, full of fun features and massive prizes.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.
