Ruby Casino Queen slot reviewed by

Ruby Ruby Ruby sang the Kaiser Chiefs memorably in the charts several years ago and it seems their call has been heard as Ruby the Casino Queen has come to town and has sat herself at the throne of Microgaming Casinos as the star of her own eponymous slot game.

Ruby Casino Queen is actually not an original game, it is important to point this out. The slot is actually the same game as the Rockabilly Wolves slot released back in April 2019, but updated with a new theme and brand new graphics and sound, but the actual mechanics and pay outs of the slots are identical.

That's not a bad thing. Some of the very best slot games (Thunderstruck II and Immortal Romance leap to mind) are very similar to each other in many respects and what is better than one good slot, than two?

So the question is whether our Ruby is the Casino Queen that offers benevolence to her subjects, or whether this high volatility slot, is one that will tax her fans to the hilt in the form of snatching away their cash for little reward. We decided to take a look and and find out which of the two scenarios was the case.

Ruby Casino Queen is essentially the exact same game as the earlier release Rockabilly Wolves, but just upgraded with a new theme and graphics. The graphics and sound on this slot reflect a casino theme and they are nicely done, as you would expect given the quality of the original release. The graphics are stylish and elegant, and the soundtrack is pleasant enough without being irritating.

The main controls of the slot are on the right-hand side of the screen, not at the foot of the reels as is standard and there is an auto-play option available for those who like to do something else while the game plays.

What is on the reels?

There are a number of different symbols on the Ruby Casino Queen slot and these begin with the very low value symbols, the four playing card symbols of diamond, hearts, spade and clubs. These pay from 0.3x your bet up to just 1.5x your bet for five across a pay line, so these are not going to be offering you any big wins, unless you can land them stacked of course (all symbols are stacked up to three high on the reels so offer the chance of multiple line wins).

In addition to this there are two higher value stacked symbols, one with Lucky 7s on, which offer pays from 1x to 6x your bet and the other with diamonds on, which offers wins from 1.2x your stake up to 8x your bet.

Ruby is the girl behind the slot name and she is also the highest value standard symbol. She offers wins from 1.5x your bet for three symbols across the reel, up to 20x your bet for five across the reel and her symbol is stacked three-high, offering the potential for multiple bigger value wins.

Wild features

The base game contains just one Wild symbol and this is the standard Wild. This, like the regular symbols in the game, is stacked up to three high on the reels and you can land a cash prize for landing Wilds across the reels, earning between 1.5x your bet for three Wilds and up to 20x your bet for landing five across the reels on a pay line.

Each Wild landed can also serve as a substitute for the other standard symbols on the reels and these can help create bigger or additional wins on the reels. There are two other wilds, Multiplier Wilds and Sticky Wilds, that also offer the same value pays as the standard Wild, but these are only activated once you trigger the Free Spins bonus game.

Free Spins features

There's only one feature on the Ruby Casino Queen slot and that is the Free Spins bonus round. This is triggered when you land three of the Free Spins Scatters in the middle three reels of the base game. One nice touch is if you land two of the Scatters, you get a Free Respin of the other middle reel without a Scatter to try and land the bonus.

When triggered, you receive 9 Free Spins and you also have the standard Wild from the base game replaced by two different Wild symbols for the duration of the bonus. You have a Sticky Wild symbol, which will start off on the Free Spins symbol space on the third reel and you also have a Multiplier Wild which can appear anywhere on the reels in the bonus round. When you land any other Wild symbol in your bonus spins, then they will remain in place for the remainder of your Free Spins bonus.

As you play through your spins, all the Wilds you collect on the reels will increase in number and they will help you try and land some of the bigger value wins in the game, especially on the final few spins when you have more Wilds in play on the reels. One nice touch is that each time you land an additional Wild on the reels, you receive three more additional Free Spins, which can radically increase the total number of spins you get in the bonus game and offers you a good chance of increasing the value of your win.

Best feature of the Ruby Casino Queen slot

There's no doubt that the main feature of the Ruby Casino Queen slot is the Free Spins bonus game and with the different types of Wild symbols on the reels in that bonus feature, you are able to land some sizable wins. You'll likely need them as this is a higher variance slot, but if you are able to trigger the slot then you can land some massive wins in the game, up to 6,411x your stake if you hit the big wins in Free Spins.


Essentially, what you have here is the same slot structure as you found on the Rockabilly Wolves slot released in April, just with a new theme. We quite enjoyed the Rockabilly Wolves slot and although the two games are very similar in every respect, I think the first game is probably just the better of the two as it is less generic and has a more original theme. That said, if you like one of the games, you are almost certainly going to like the other and there's nothing to dislike on the Ruby Casino Queen slot. At worst, it offers slot fans an option to play a great slot under a different theme.
