Yet another slot machine is available through Microgaming, though it is designed for them by Just For the Win. This partnership seems to work very well, and this time it gives us a game which relies on precious stones and riches, well enough designed and capable of delivering big prizes.

Ruby Casino Queen will give you 5x3 reels, along with 20 active lines, a type of setup that is not a surprise to see these days. You will get a game with excellent potential, capable of delivering wins of up to $320,550. Along the way, the game will spice things up with its scatters, re-spins, free spins and sticky wilds which have multipliers as high as 6x.

Betting and Prizes

The minimum bet of Ruby Casino Queen starts at $0.10, and from there it goes up, to as much as $50 per spin. The value of the coins which are used vary between $0.01 and $1.

Prizes will look particularly good once the multipliers from the free spins are finished with them, and they’re boosted by up to 6x at that point. You can win a prize of 320,550 coins at most, which is a fairly impressive return, of over 6,400x total stake.

As always, the RTP is one more element that we consider when we look at slot machines and how they pay. With its 96.03% calculated return, Ruby Casino Queen is fairly average, particularly for the year when it comes out, in 2019.

Ruby Casino Queen Slot Features

Say what you will about the game’s theme, it might be boring for most, but there are areas in this game where the developer makes up for it. I would count the game’s features among the best parts about it.

One of the symbols you’ll see here is the scatter, which you typically need to show up three or more times, to get into the free spins. If that happens, you get a 2x multiplier and a single sticky wild. Each new wild that you get after that turns sticky as well, while also increasing the multiplier. The highest multiplier that can be reached here is 6x. Win additional free spins, by landing wilds on all reels.

If you have only two of the scatters required to get the free spins, then a re-spin triggers, as a second chance at getting the third one that’s needed.

Wilds do exist, and the game will use them either in regular, multiplier or sticky versions. Whatever secondary offer they have to make, they also act as substitutes for any regular symbols that can form combinations on their lines.

Theme & Design

The theme of Ruby Casino Queen is inspired by a girl that’s surrounded by rubies and other gemstones, with secondary symbols taking the form of 7s or card suits. Some of the symbols you see here will come stacked, particularly the ones that also have bigger prizes to offer. I’m not very impressed with the chosen theme, it’s just too common of a pick. The graphics are better than the theme might suggest, but taken as a whole, I wouldn’t consider this part to be a strength of this slot.


Ruby Casino Queen is a good game overall, a joint JFTW / Microgaming release that is fun to play, though that’s mostly due to the features/payouts involved, not its story or graphics.
