Kings of Crystals Slot (Microgaming)

Kings of Crystals Slot (Microgaming)Microgaming and All41 Studios have teamed up for a joint slot release, and this time, we get a game by the name Kings of Crystals.

The slot features lots of fantasy-themed designs and from what I gathered, it tells a story that involves lots of magic.

I’ve had fun with previous releases by these two developers, and I could not let King of Crystal pass me by.

Here are the details that you need to know about this new slot:

Game Set-Up

5x4 reels and 40pay lines is the initial design that I got, however, as I got deeper into the game, the game area expanded. This expansion can go 5x6 with a whopping 100 lines.

There are plenty of features inside, among them the Free spins bonus, Expanding Wilds, Nudges, Stacked Symbols, Stacked Wilds, and a Win Multiplier.

There are many exciting features inside but the reel expansion system is one that you should have fun playing with.

Betting and Prizes

If you love playing for real money, you will get a chance to place bets of between $0.20 and $20 per spin.

Kings of Crystals can pay equally well as the slot offers a top jackpot of over 10,000x the stake. For the RTP, you get to enjoy a great figure of up to 96.4%, but you will also get to work with fairly high volatility.

Kings of Crystals Slot Features

The most obvious feature here is the stacked W wild that serves as a substitute. I love its work because, with its help, I could create more winning combos. I noticed that the W feature only appears on reels 2-4.

I also noticed that the slot offers three types of free spins, and to trigger any of them, you will require the help of the scatter. The scatters will appear in various colours like blue, red, and green variants.

The Red Scatters are what assisted me to trigger 5 free spins, but the Nudging Wilds mechanic came in to offer some help. It is the same help that allows for the expansion of the game area where you can get up to 5x6 reels, and 100 active lines.

With the Green Scatter, the slot offers 10 Jackpot Free Spins. It’s a fun way of doing things as you need to collect some letters to form a jackpot name. If you are lucky, then you get to hit the top reward (10,000x the stake).

The Blue Scatters are responsible for activating the 5 Multiplier Free Spins. Here, it is possible to get wins as high as 10x higher than usual paid on each round. Each time you get a random multiplier value.

Red and Blue scatters my trigger additional free spins, but this can only be possible if they land while the feature is in action.

Kings of Crystal also offers free spins that have active multiple forms of modifiers.

Theme & Design

It looks like the slot has borrowed from a fantasy setting as you can see from the medieval castles that are located in the background.

Several premium symbols are present and they come in the images of wizards donning elemental auras (ice, fire, nature’s green), or a chalice.

There are six Royals (9 to A) that serve as low pay icons.


Kings of Crystals is quite interesting, and I had lots of fun playing it. It's loaded with great features and one of the highest RTPs possible on a modern slot.

However, it also comes with very high volatility that is best handled by experienced players.
