Ruby Casino Queen Slot Review

Released June 2019

The Ruby Casino Queen 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 Ruby Casino Queen is 3.97%. 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.

Ruby Casino Queen is a 5 reel game that is 3 symbols high. The game uses traditional paylines, with 20 in total, playing from left to right.

Special Symbols

Wild – The “Regular Wild” symbol will substitute for all symbols other than the Free Spins symbol and also come stacked.

Free Spins – The Free Spins symbol is only available on reels 2, 3 and 4 and will trigger the feature if you can land 3 or more of them on a single spin.

Stacked Symbols – The “Regular Wild”, the “Ruby Ruby”, the “Pink Gem” and the “Number 7” symbols all come stacked.

Bonus Features

Re-Spin – If 2 “Free Spin” symbols land on 2 out of the 3 available reels, then to two reels with the symbols will stick in place whilst the 3rd symbol re-spins, giving you another chance to try and trigger the feature.

Free Spins – If you trigger the Free Spins feature you will be given 9 Free Spins. The Free Spins begins with a x2 Multiplier for every win. Additional Free Spins can be awarded but only once. During the Free Spins 2 new Wild symbols become available, the “Sticky Wild” and the “Multiplier Sticky Wild”:

Sticky Wild – A Sticky Wild will remain in place for the remainder of the Free Spins and will substitute for all symbols other than the Free Spins symbol.

Multiplier Sticky Wild – A Multiplier Sticky Wild will increase the size of the multiplier by 1, up to a maximum of 6 times the bet, every time a new one lands on the reels. The Multiplier Sticky Wild will stick in place for the remained of the spins and will substitute for all symbols other than the Free Spins symbol. Only one can land per reel.


Whilst this is not a terrible game it is far from being Microgaming’s finest moment. There are a couple of games out there already that are very similar to this one, in fact I would go as far as to say that barring different symbols and different titles for them and for some features I reckon there is essentially no difference between them at all. You get Free Spins, Wilds and some expanding symbols but not a whole lot else. The house edge is OK but still sitting at a level that we would consider to be higher than average.
