How to Play
All action takes place on a playing field with 5 reels in 4 rows and 40 lines and you can expand the grid to 5x6 with 100 lines. The game revolves around 3 kings looking for their crystal crowns and they are collected as Scatter symbols. Collecting Scatters can trigger a Bonus round or a combination of 2 or all 3 features, and the round with single/double features can also be enhanced with additional features as they progress.
To start searching for lost crowns you need to:
- Open Kings of Crystals at your favorite casino
- Click on the menu button to view the paytable and rules
- Choose a bet: from €0.20 to €20
- Spin the reels!
Kings of Crystals RTP and Volatility
High volatility comes with 96.40% default RTP.
Well, you will not have the easiest journey as a brave knight, who set out in search of the lost crowns. The game has high volatility, which means that at any moment you can get a series of dead spins, but do not despair, because any successful spin can bring you a big prize. As for the RTP - it is 96.40%, which is slightly above the industry average.
Theme
As we said in the intro, All41 Studios has already tried its hand at many different themes, but this slot is their first foray into the medieval-fantasy slot genre. Kings of Crystals tells the story of three kings who are looking for their multi-colored crystal crowns and you, as a selfless knight, are ready to help them in their search. The theme is good, but the visual presentation didn't immediately grab us, and upon closer inspection, it seems somewhat outdated.
As you may have guessed, the 3 kings are the high-paying standard symbols and the low-paying icons are the classic stylized playing card suits. The ‘W’ on a purple background is the Wild which lands on reels 2, 3 and 4 and the crowns are the Scatters. There is also a Coin symbol that can give you a cash prize or a letter.

Mobile Compatibility

If you don't want to be tied to one place while playing, just use the mobile mode of this slot machine! Fortunately, All41 Studios has created it using HTML5, which allows it to load quickly on all modern mobile devices and adapt to small screen sizes. Just go to the casino from your phone or tablet, press the ‘play’ button and enjoy fun gameplay!
Bonus Rounds & Free Spins
Bonus Rounds
The crowns are collected in the corresponding meters in the left corner when they appear on the playing field and this eventually triggers the Bonus round or combo. The functions have different modifiers depending on which crystal color you activate. The Bonus round can be improved and combined with modifiers from other features.
Nudging Wilds Free Spins
This Bonus round will trigger 5 Free Spins and you will get Stacked Wilds that nudge to completely cover any reels they appear on. The Bonus round comes with an expanded 5x6 playing field and 100 paylines, and red Scatters land to reveal a random number of extra Free spins that are added to your account.
Multiplier Bonus Round
The last Bonus Round triggers 5 free spins and you get a random 2x, 3x, 5x or 10x multiplier per spin. You win a random number of extra Free spins when blue Scatters land during this feature.
You can activate different combinations of bonus rounds directly from the base game. The best you can hope for is 10 Free spins where all 3 modifiers are combined. All 3 bonus rounds can also be upgraded with additional modifiers when you collect Scatters of a different color than the one that belongs to your current feature.
Bonus Buy
If you don’t want to wait for a chance, you can use the feature, this slot will offer you an inclusive menu of 7 options: from 20x the bet for Nudging Wild or Multiplier Free spins up to 110x your stake for Free spins with all 3 Features active.
Kings of Crystals Demo Play
No player wants to buy a pig in a poke, yeah? Luckily, you can play Kings of Crystals for free! This game by All41 Studios comes with a free demo mode. Using it, you can set the reels in motion to create combinations and trigger bonus features by betting with ‘fun’ coins instead of real money. Of course, if you select this mode, you will not be able to withdraw the wins, as they are not real, and to win real money, you need to play for real money.
Max Win
Find crowns to win up to 11,650x!
It's really unclear to us how many Scatter symbols you need to collect to trigger the bonus rounds, but during our test session, they appeared regularly. The maximum win you can get in this slot is 11,650x the stake.
Jackpot
During the Jackpot Bonus Round, the gold coins may show 1x-10x prize or a letter. The letters are collected in the corresponding counters and you will receive the jackpot, the name of which you can write in full using these letters. Mini, Minor, Major and Grand Jackpot pays 25x, 50x, 500x and 10,000x respectively (with a minimum bet amount).
Overall Rating
The visual presentation did not attract us as it seems somewhat outdated. We also don't like the fact that there is no info about how many Scatters you need to collect to trigger the Bonus rounds, but, as we said above, during our test session they were triggered regularly. But unfortunately most of the time they didn't bring in big prizes, so max win seems far-fetched if you don't get the Grand Jackpot.
We liked the ability to combine Bonus rounds, but even the Mini jackpot seemed difficult in most cases, and the combination of all 3 Features does not guarantee a bigger payout. We're a bit overwhelmed by all the Feature combinations, but we're not thrilled with how they work.

The reality can be not so great compared to ur expectations. The slot tends to go on down streaks. And I believe it’s almost impossible to end with positive session without triggering feature. Feature are triggered totally random – not by collecting 3 Scatters. And that’s kinda annoying.
Green bonus, imo, is the best, as u can win jackpot from it.
