Description of the Slot 

Working in the smelting heat of a furnace comes with its merits. Here, you can forge anything from metals to precious gems, provided you have the materials. Eyecon’s latest release, Crystal Furnace, revolves around this theme, where precious symbols drop onto the reels to produce excellent rewards. 

Crystal Furnace unfolds on a standard 5×3 grid layout with 10 adjustable paylines. Although a relatively uncomplicated slot, there are a few unique features in the game that can increase your winnings to a considerable degree. Let’s explore the slot in greater detail to learn more about it.  

Design and Audio

The action of Crystal Furnace takes place in a large furnace with a glaze from golden fire filling the entire space. The reels are transparent and give us a clear look at what is happening at the furnace. From the looks of it, this is not an ordinary furnace but feels like the hub for creating legendary weapons and precious gems. Every time you hit the spin button, the fuming blaze from burning coals rises upward to the grid. 

The soundtrack carries a somber and somewhat eerie appeal. Mixed with the music is a clanking of stones and iron. Although no one is working on the furnace, the background score ensures the work keeps going.


The slot gets rid of any complexity by avoiding multiple features. Instead, it keeps the gameplay simple by limiting the action to the base game. However, the game has a unique feature trigger, which can increase your chances of hitting something impressive. 

Expanding Wild Respin Feature 

Landing at least one hammer wild symbol on reels 2, 3, and 4 triggers the special feature. The wild symbol expands to fill an entire reel, and then payouts are only computed. Moreover, you win a respin where the expanded wild symbol sticks to its position. 

If another wild symbol lands on the remaining two reels, wild expansion and respin occur again. The feature can be repeated up to 3 times with three available reels for wild symbols. Note that the hammer wild symbol substitutes for all paying symbols. 

Both Ways Pays 

Unlike most other slots, the Crystal Furnace slot accepts a win line from both ends: left to right and right to left. However, only the highest win is paid per line.  


Since Crystal Furnace has adjustable winning ways, bets are made per line. Symbol credits are multiplied by the bet amount per line to calculate payouts. With this information in mind, let us move to the slot’s paytable.

The paytable consists of various crystals, Lucky 7, and BAR symbols. Landing 5 BAR symbols across a payline provides the highest symbol payout of 150x the bet or 1500x the stake per line. Unfortunately, the game provider didn’t specify the slot’s max win potential.


Crystal Furnace looks like an ancient forge, where grand weapons and precious crystals are forged. Land your hammer on the metal and watch the melting steel transform into a sword or something else. 


Crystal Furnace is a low volatility slot. Therefore, expect frequent wins in the game, with payouts mainly ranging from low to average. 

About the Game Provider 

Eyecon started its journey as a computer game company in 1997. In a matter of two years, it turned its attention to creating online casino games. The company kept releasing successful slots over the years and, in 2016, was acquired by Playtech. The acquisition resulted in Eyecon launching an advanced HTML5 framework. Currently, the game provider holds over 90 highly-engaging games in its portfolio. 

Eyecon never shies from venturing into new areas, and this becomes evident from the company’s partnership with crypto gambling platforms. Therefore, it is no surprise that several top-rated Eyecon slots are now listed on Bitcoin and other crypto casinos. 

Final Considerations 

Crystal Furnace draws players’ attention with its simple gameplay and payout features. While the lack of free spins bonus game might not convince some players, it’s best to look at this game as a fruit slot. And why not? It does have Lucky 7s and BAR symbols! But most importantly, Crystal Furnace stands strong in numbers with an impressive RTP of 96.56%, which is indeed pretty impressive for a 2022 slot.
