Microgaming added Queen of the Crystal Rays to its arsenal, a slot that comes from a less known developer called Crazy Tooth Studios. The 6 reel, 5 payline game is very much inspired by Wonder Woman, although perhaps rather than the Amazon, this queen took a trip to galaxies far, far away.

With a generous RTP of 96.7% and an Any Adjacent Pays feature, it certainly seems as though there’s a lot to play for. But let’s take a closer look at what the slot offers in terms of payouts, frequency and special features to ensure we’re not just being taken in by a pretty face.

  • Frequent wins keep things interesting
  • The slot incorporates the Any Adjacent Win mechanic, boosting winning combinations in the base game
  • The base game features a multiplier wild symbol
  • Queen of the Crystal Rays is available to players in Canada
  • Low payouts in the base game
  • One out of the only two features is randomly triggered, which can be frustrating
  • There’s no jackpot

Queen of the Crystal Rays - Theme and Background

Queen of the Crystal Rays runs on a very dynamic concept. If I had to try and label it, I would say that the theme is smash up of comic book style graphics, overlaid with futuristic digitized appeal.

The music is slightly electronic, and there’s something very hypnotic about the entire experience. Everything is centered on crystals, magic and light using very bright neon colors. The layout is very animated, with glitzy arrows constantly traveling up and down the grid on either side, poised to shoot Wilds when the time is right (more on this feature below).

Across the reels you’ll find a series of themed symbols including several colored crystals (purple, red, green, blue), a multicolored spherical crystal (the Scatter), a tilted chalice, a glowing chest, a bonus symbol, a 2 x multiplier symbol, and the Queen herself in all her Wonder Woman-style headband-ed glory.

The music is beautiful yet unexpected. Made up of wind instruments and pretty chiming noises, I had no inclination to hit the mute button whatsoever. Shocker.

Queen of the Crystal Rays - Gameplay

The slot hosts two main features, designed to trigger larger wins and keep players in the money. It’s all fairly straight forward, which is a welcome change, but here’s a breakdown for you just in case.

Queen of the Crystal Rays Crystal Ray Symbol

Crystal Ray Feature

This feature gets triggered randomly during the base game, increasing the paylines from 25 to 50 – essentially doubling the slot’s payout potential. And when the feature triggers, it’s quite a sight to behold, with crystals shooting beams of light and crystal reflectors spinning by.

When all the melee dies down (basically when the spin is over), Wilds will occupy the glowing path created, having been fired from the sidelines, substituting for any paying symbol. The added kicker is that the feature could also award a 2 x multiplier on top, boosting your potential win astronomically.

QueenOfTheCrystalRays Bonus Symbol

Queen Of The Crystal Rays Bonus

To trigger this feature you’ll need to land 3 or more Scatter Symbols anywhere on the reels. Succeed here and the grid will transform into a fresh board populated with multiple credit values and crystal reflectors.

Things will kick off with 4 bonus rounds, and each round offering a higher multiplier then the round before, starting at 2 x and going all the way up to 5 x your bet. Crystal rays will blast away at the credit values, boosting your total win.

Queen of the Crystal Rays - Payouts and Wagering Limits

With a potential maximum win of just over 2,597 x your bet, the slot offers the possibility of a very healthy win. But you don’t have to hold out for the ultimate prize, because there are smaller, but still considerable, gains to be made elsewhere.

Of all the symbols, the Scatter is the most rewarding (this is also the symbol responsible for triggering the Bonus feature). Landing 3, 4, 5 or 6 Scatters will offer you wins of up to 5 x your bet. In the base game, a 2 x wild multiplier can substitute for all paying symbols, doubling every win.

The most valuable symbol is the Queen of Crystal, followed by the treasure chest, chalice, and cauldron. The different colored gems are all low value symbols, standing in place of the usual card suits. The slot benefits further from the Any Adjacent Pays feature. This means that yours win frequency is increased because winning combinations can be found anywhere on the reels. The only requirement is that 3 or more matching symbols are present at the end of the same spin.

Final Verdict

Queen of the Crystal Rays


I couldn’t quite make my mind up when it came this slot. I liked the theme idea, though I do feel Marvel’s Wonder Woman has been pretty heavily ripped off. But the ethereal crystal concept was diluted by a very digitized design, that made me feel like I was playing some 80s space invader game.

That said, the special features were fairly easy to activate, one of which is triggered at random. Wins aren’t large, but definitely helped along by the liberal use of multipliers throughout both the base game and the special features. I suppose this balances things out.

Overall I would say Queen of the Crystal Rays is suitable for players who would be satisfied with Medium wins on a semi-regular basis. I can’t quite work out how to get near the advertised 2,597 x maximum win, but you are definitely guaranteed a fairly spectacular light show.
