Queen of the Crystal Rays Slot Review

Released August 2019

The Queen of the Crystal Rays slots game can be found at Microgaming casinos. Microgaming as a standard now publish the slots house edge information of all their games at any online casino that holds a UKGC license (this is a requirement for all UKGC licensed casinos). As such we can say that the House Edge of Queen of the Crystal Rays is 3.3%. When playing at any venue that does not hold a UKGC license and does not specifically publish the Return to Player information for their game, this information should be used as a guideline only as we cannot confirm whether or not this game is configurable.

Queen of the Crystal Rays is a 6 reel game that is 4 symbols high. The game uses 25 different paylines during the base game. The paylines form winning combinations across adjacent paylines, meaning your wins to need to begin at the far left of the reels. When the Crystal Ray feature is in the play the number of paylines will increase to 50.

Special Symbols

Wild – The Wild symbol will substitute for all paying symbols. Wild symbols are only available during the Crystal Ray feature.

x2 Wild – The x2 Wild symbol will substitute for all paying symbols and will multiply the any wins they help to form by 2. X2 Wild symbols are only available during the Crystal Ray feature.

Bonus – The Bonus symbol is needed to trigger the slot’s Bonus feature. You need three or more of them anywhere on the reels at once to trigger the feature.

Prisms – Prism symbols do not pay at all and only come into play during the Crystal Ray and the Bonus feature. When Wilds are shot onto the reels, if the hit a Prism symbol then more Wilds will be added to the reels, but the ray will veer off in a different direction.

Bonus Features

Crystal Ray Feature – The Crystal Ray feature is a random feature. When it triggers the number of paylines will increase to 50 and the ray guns at the side of the reels will become active. They shoot Wilds onto the reels and if the rays it Prisms then the number of Wilds will increase as the ray veers in a different direction.

Bonus – If you can land 3 or more Bonus symbols anywhere on the reels at once then you will trigger the Bonus feature. When this happens 4 Bonus rounds will be awarded. At the start of the Bonus round the gameboard is filled with cash amounts. Crystal Rays are shot across the gameboard and a multiplier is applied to the cash amounts the ray shoots across.


Queen of the Crystal Rays is a decent looking game, very reminiscent of slots like Artic Valour and Crystal Rift. The slot’s main features centre around the principle that crystals can bend light, which means that when the rays are shot onto the reels, leaving behind trails of Wilds that the prisms can bend that light and leave additional trails in different directions. There are no Free Spins but you do get a bonus game. The house edge is offering good value for money, meaning this is a slot worth checking out.
