In a land far away from ours, there are three kings. For some reason, these kings have a special connection with crystals. Why is it so? We’re not sure, as we haven’t been given an in-depth story regarding these characters, so plenty of it is left on your own interpretation. This magical story is created by All41Studios. These guys are Microgaming partners, so you might have come across some of their titles before. Even though the origin story is unknown, we know for a fact, that the Kings of Crystals slot is capable of producing some crystal worthy wins. If this caught your attention, then stick around.

Gameplay and Payouts

Kings of Crystals visuals aren’t overly impressive. In the background, we see some ruins and a castle with some green, forest-like scenes visible on the bottom. During the main game, the layout is 5 reels and 4 rows big but it extends up to 6 rows high during the bonus game. Symbols are further on playing with this medieval fantasy idea, as top symbols are 3 kings, a magical chalice and a gauntlet. Low symbols of 9-A have a simple metallic finish. Kings of Crystals by default comes with 40 lines.

Kings of Crystals is a slot with maximized volatility and 96.40% RTP. At best, this slot can produce a win of 10,000x. We definitely have no complaints with this stat. All41Games have decided to with a 0.20 – 20 bet range, so we could say that some limitation has been implemented. You should be able to run Kings of Crystals well on any device, as full platform support is available.

Bonus Features

On Kings of Crystals, there are 3 different scatters – red, blue and green. Each colour represents a different modifier that comes into play during Free Spins, once you collect enough scatters.

Red scatters will award 5 Free Spins. During this feature, the layout extends and regular Wilds turn into Nudging Wilds, which will always cover the whole reel size.

During the blue scatter Free Spins variant, a multiplier of 2x, 3x, 5x or 10x will be added on each spin. Here you will also begin with 5 Free Spins.

The green scatter has the largest initial spin amount, as you’ll begin with 10 Free Spins. On this bonus, you will come across Gold Coins which reveal cash values ranging from 1x-10x. Another objective is to collect letters, so you spell the word Jackpot. This could either be a Mini, Minor, Major or Grand Jackpot, with values of 25x, 50x, 500x and 10,000x respectively.

These scatter types can also be mixed, for a chance to trigger Free Spins with multiple active modifiers. All of these bonus features can also be bought straight away with the Bonus Buy option.

The whole idea of kings and crystals is a bit foggy, as there is no set link between these things. It almost seems like All41Studios just decided to throw two things together and call it a day. The gameplay itself is decent, although nothing overly enthusiastic. Your main objective is to collect symbols and hope for the best outcome. The bonus modifiers don’t feel balanced at some points, so it almost feels like Kings of Crystals doesn’t have a solid personality, it’s a bit of a mess all-around. Still, there is the 10,000x payout up for grabs, so we’re sure some players will be interested to have a go with this slot.
