One of the iGaming kings, Microgaming, frequently collaborates with smaller studios such as All41 to deliver a wide range of games. All41 is the studio responsible for hits such as Book of Captain Silver slot and Book of Atem WowPot which have achieved major success. The developer has just returned with a new slot called Kings of Crystals that takes a bit of a different path from those released before.

A medieval fantasy game with a range of great features, the Kings of Crystals slot has 40 expanding paylines and high variance paired with an RTP of 96.40%. It’s a slot based on shiny crystals that takes place on a 5x4 grid. The jackpot bonus modifier is the main highlight of the slot, delivering wins of up to 10,000x the bet.

Slots and rare jewels and crystals are a love story that never ends. That’s never been more evident than in Kings of Crystals. It’s a mix of a classic slot with modern features that can deliver fantastic returns. You can play Kings of Crystals right now in any Games Global casino for free or for real money.

Kings of Crystals doesn’t reinvent the book when it comes to slot design. It’s your typical 5x4 grid with 20 symbols, many of them featuring warlords, wizards, and of course, crystals. These are set on a crown to be worn by the king that wins the bloody battle for the throne. Premiums pay up to 5x the bet for five on a line, with a Wild and Scatter available as well.

In visual terms, the graphics are solid, but that’s to be expected out of a Games Global slot. An epic soundtrack keeps you on your toes all the time, and the sound effects are all on point. In audio-visual terms, the slot is more than solid.

Of course, it’s a modern game that’s available across a range of devices.

You can play Kings of Crystals on your PC or laptop, but it’s far more entertaining when you play it on your phone. It perfectly sizes up to any device, including Android and iOS smartphones and tablets, no app download is required.

To start playing the fantasy adventure, you’ll need to place a bet first. Bets range from $0.2 to $20 per spin. As mentioned earlier, the action takes place on a 5x4 grid with 40 paylines, although those can expand to 100 under certain conditions.

There’s no special action in the base game, with only the crystal Scatters offering some relief. They are collected in special pots corresponding to the color whenever they land on the screen. They don’t pay but can trigger one of the three special bonus rounds that offer better payouts.

Other than that, you’re stuck with premium symbol combinations and Wilds in the base game that don’t exactly promise big wins.

There are three different bonus rounds depending on the colours of the Crystal Scatters.

• Nudging Wilds. Triggered by the Red Scatter, this option comes with 5 free spins and full reel Nudging Wilds. The Bonus Round is also played on an extended grid that raises the number of ways to win to 100. Wilds always nudge to fill the reel when they land while landing Red Scatters give you extra spins.

• Multiplier Bonus. This bonus is activated by the Blue Scatter. You get 5 slot free spins with a random Multiplier between x2 and x10. Landing Blue Scatters gives you more free games.

• Jackpot Bonus. Triggered by the Green Scatter, the Jackpot Bonus Round comes with 10 free games and four jackpots. You can see the value of each to the left. Gold coins can land on the reels during the Bonus, awarding instant cash prizes between x1 and x10. The Mini, Minor, Major, and Grand jackpots pay 25x, 50x, 500x, and 1,000x respectively.

The Kings of Crystals slot RTP is set to a solid 96.40%. That’s a bit over the average for a highly volatile slot with a decent hit frequency. The maximum win you can hit is 10,000x the bet.

Kings of Crystals may be unimpressive in the base game, but the three bonus rounds more than make up for the early lack of action. Players will certainly be impressed by the different modifiers and the four jackpots that can deliver great wins. 

If you’re into medieval fantasy slots and many modifiers, Kings of Crystals is a great pick you can find in the best online slot sites.
