Kings of Crystals Slot 

The royalty of a fantasy realm is at the centre of the theme in this Kings of Crystals slot, an All For One Studios creation that saw a wide release onto the online casino scene in March 2022. This original instalment has proven to be a popular entrant in the developers' catalogue, so much so that it actually spawned a sequel in the form of Kings of Crystals 2 Power Combo. From multipliers in the main bonus round, all the way to mechanics which can change the layout of the playtable, there are a handful of innovative elements within the Kings of Crystals slot!

Kings of Crystals Game Background 

Backed by some stone textures, the reels in the Kings of Crystals slot are 5x4 in size, with this set-up having 40 paylines included. These work from left to right across the playtable, which is surrounded by a stone brick frame, with the titular logo sitting at the top of this on a red banner. To the left of the reels, the Mini, Minor, Major and Grand fixed jackpots can be seen, like in many other online slots, with 3 coloured gemstones being visible directly beneath these, fitting when factoring in the name of this Kings of Crystals slot.

The reels in the Kings of Crystals slot sit in front of a large, mediaeval castle, with watchtowers, portcullis and battlements being visible all around the towering stone walls. A river which acts as a moat sits around this defensive structure, with thick green foliage visible in the foreground too. A sunset hue casts a warm orange glow onto the setting in the Kings of Crystals slot, with all of the intricate visual details separating this release's aesthetic from titles such as Knights of the Golden Egg and Cygnus 5, which also feature castles.

Kings of Crystals Slot Symbols 

Presented in silver fonts with some sharp edges, the usual card royals found in many other online casino games serve as the lower valued symbols in this Kings of Crystals slot. The higher-valued ones are made up of some other mediaeval items and fantasy king characters, each of which is backed by different coloured frames.

Lower Value Symbols:

Silver 10

Silver Jack (J)

Silver Queen (Q)

Silver King (K)

Silver Ace (A)

Medium Value Symbols:

Blue Goblet

Orange Gauntlets

Higher Value Symbols:

Blue King

Orange King

Green King

A purple regal seal is one of the bonus symbols in the Kings of Crystals slot, acting as the sole wild symbol in this fantasy-themed title. There are also a series of gold coins with castles depicted on them, which could have prize values displayed on them as well as red, green and blue crown scatters too.

Kings of Crystals Bonus Features 

The simplest of bonuses which All For One Studios have added to this fantasy-themed Kings of Crystals slot is the regal seal symbol. Being a wild, this allows it to substitute for all king, mediaeval and silver card symbols if it lands across reels 2, 3 or 4 in a position to form or increase a combination.

As we mentioned earlier, the gold castle coins in the Kings of Crystals slot could potentially feature prize values upon them, with these being between 1x and 10x the player's bet stake. However, one detail we haven't touched upon in regard to these castle coins is that they could also reveal letters. If this occurs, these are collected by one of the jackpot values next to the reels and spelling out one of their names in full could potentially trigger that same 

fixed prize value, something which differs quite a bit from other online jackpot slots.

If any of the red, green or blue crown scatters are landed, this could see them collected by the crystal of the same colour off to the left of the Kings of Crystals slot. At random, this collect activation may trigger bonus rounds, with these differing depending on the triggering crown colour.

Red Crown Free Spins: Could trigger 5 free spins that extend each reel by 2 rows and introduce nudging wilds that fill a full reel.

Green Crown Respins: Introduces a respin round in which any landed castle coins lock in place, much like in titles such as Silver Bullet Bandit Cash Collect.

Blue Crown Free Spins: Could trigger 5 free spins during which each spin is allocated a multiplier valued at 2x, 3x, 5x or 10x.
