The game cannot measure with the games portraying a real historical legend, such as the Arthurian myth for example. Nor with a game that reflects the fame of a blockbuster, such as the Game of Thrones, to name one.
But with its simple plot about 3 princes striving to put the crown on their heads, Kings of Crystals is a surprisingly good video slot that blends unorthodox characters and fictional schemes.
The 3 Kings start as enemies (in the base game) fighting to take control (which crystal will be collected first) and eventually join forces to effectively advance the efforts of the Crystal Kingdom of alliances (as the features can merge into the various Bonuses) providing more power when they work together.
The game comes with a fine design, where good visuals and audio take the adventurous royal atmosphere to a level of sophistication.
The symbols of the 3 Kings show a nuance of the fiction (each with its own colour crystal – distinguishable), and while All41 Studios had already slots based on Egyptian, Roman and Ancient Greek themes, the Medieval content here is the first for them. Having said that, here we don’t feel a drop in quality from the previous great work of this Estonia-based Indi Studio, compare for example to:
- Arena of Gold
- Temple of Medusa
- Book of Atem and
- Book of Atem WowPot are strong releases, and King of Crystals undeniably keeps the reputation of the Studio intact.
This is a game with an initial set of 5×4 playing field and 40 paylines, which can extend to 5×6 with 100 paylines in some of the Bonus rounds. While the hit rate is very high (at near 39%), the paytable cannot be called generous:
- Wilds and 3-types of Scatters – don’t pay
- The Green King – on the high end of the provision board – pay 5x for 5OAK
- The Red and Blue Kings, the knight glove and a goblet – on the middle-value rate – all pay 2.50x total bet for 5OAK, and
- A to 9 cards – all pay 0.75x the total bet for 5OAK on a payline (each of these 5 icons provides a payout for its max combination under the bet).
Very low paytable, we must admit. And there are no features included in the base game to boost the results. This explains the immediate conclusion that a balance increase is only possible in the FS Bonus.
The stats of this High Volatility game do improve when we realize the theoretical return – set very high (RTP of 96.40%) and the maximum win prospect of 10000x the bet, both of which are respectable figures, and attestation for intriguing sessions with possible huge rewards (in a long-range, of course).
The Estonian Studio had 3 main FS modes built-in, but also included the possibility of combined execution, making the sessions enthralling despite the poor paytable.
Extra Wilds, Scatters collections, Multipliers, Nudging, Adding reels, features upgrades, Jackpots and Bonus Buy – have been planted to the taste of a large group of gamblers, despite some minor imperfections (some don’t like the pale look of the youngest – Blue King, others want to know the exact amount of Scatters needed to trigger each feature).
In conclusion, with its heroic soundscape, fine graphics and wonderfully carried out features, this slot belongs to the high-class games. The tempo in the main game can be a tad flat for some players, but it is a preparation for the upcoming great entertaining (in the various Bonuses).
The return and the winning prospect match fully the level of risk here. That’s why we recommend Kings of Crystals to all players who have the patience of piling Scatters collections and opening great rewards. (Short sessions are bound to fail.)

Bonus Features of Kings of Crystals slot
- Wilds – The encrusted with gold letter “W” is the Wild element in the game. It is a non-value symbol that lands only on the central 3 reels and is employed with the usual substitution for all symbols (except Scatters) in the attempt to build win combinations on the paylines.
- Scatters & Free Spins – The 3 types of Crowns with Green, Blue and Red Crystals atop are the Scatter symbols. No direct value is attached to them, and they only matter to be amassed throughout the base game and trigger a specific FS mode. Additional Scatters can also be accumulated within the Bonus itself.
At random any 1, any 2 or all 3 Crystals will start glowing, showing the radiation power and the start of the corresponding colour Bonus.
So, the Bonus may begin with 2 concurrent options, which do not increase the length of the Bonus, but combine the features and certainly boost the results of the FS.
The ultimate variant, of course, is to start the Bonus with all 3 options, mixing all possible features (the developer calls this premium variant as “King of them all”). - The exact meaning of the 3 FS modes and their features is shown in the chart below:
- Bonus Buy – For all the agog players who have enough funds, the Studio developer has inserted a buy option. There are 7 different variants of single or mixed features. With the cost of 20x/45x/55x/65x/110x, the purchased Bonus mode will automatically start on the next spin.
