Kings of Crystals Slot Machine – Free Play & Review

The fantasy genre is well represented in the slot machine industry, and we see one more example of it with Kings of Crystals. You’re not going to see orcs or dragons in this one, but there are human warriors and various elements and crystals shown on the reels. A medieval setting is used, and we see a large castle in the background.

Among the symbols that are going to find their way to those reels, the bottom ones are the Royals, made out of metal and sporting similar designs in each case. The better symbols will show us images of goblets, iron gloves, and the three kings. There are also three types of crystals, and images of W wilds.


Kings of Crystals was designed by All41 Studios, but as we’ve seen so often lately, the slot is going to be an exclusive at Microgaming casinos. There are plenty of other examples of games that the two have collaborated on, including other excellent slots like Alchemy Fortunes, Mayan Eagle, or Book of Atem.

How To Play It

Kings of Crystals comes with a betting range that feels common these days. $0.20 is going to be the lowest point for it, while $20 will be the highest bet allowed.

You’re also going to discover a system where 40 paylines are available initially on its 5×4 reels. As the game area can have up to 5×6 reels, the number of lines can get a boost as well, up to 100 paylines.

Special Features

There is limited use for the wilds of this game. Landing only on the middle three reels, they act as standard replacements/substitutes, and they can help you out when forming new combinations.

A collection mechanic is available, where you get crystals of three types to their respective meters (bottom left area). These are colored in red (Nudging Wilds), green (Jackpot Collection), or blue (Line Win Multiplier).

5 free spins with Nudging Wilds: uses stacked wilds, which are nudged to cover the entire reel. Uses 100 lines on 5×6 reels.

10 free spins with Jackpots: you can claim one of the four fixed jackpots. They go from 25x to 10,000x the stake (Grand Jackpot). You collect special symbols with letters, to claim those jackpots.

5 free spins with Multipliers: these are random multipliers, ranging from 2x to 10x.

While you can get a single version of the free spins, you can also combine them, with all three types of features active during 10 free spins. It all depends on the moment when you finish collecting the crystals in the different meters.

Maximum Payouts

The top prize in Kings of Crystals will take the form of the Grand Jackpot. It’s going to have a value of 10,000x the stake, and it can be claimed during the slot’s free spins. The regular combinations don’t get close to that, as they pay up to 5x per combo, or 200x per spin (2,000x during free spins if the 10x multiplier is active).

Like most new slot machines we see these days, the volatility of this game is expected to be high. You might win big, but chances are that you’re going to lose your money quickly. The RTP can be very good, up to 96.40%, but that’s just the maximum value of the range, and a lot of casinos can use lower settings.


Kings of Crystals doesn’t look bad at all, it’s a slot machine with good rewards and a decent mix of special features. The features feel different from those that most slots use, and that could be enough to make it interesting, despite the boring graphics.
