Crystal Furnace Review

Eyecon is known as a light-hearted slot developer that continuously releases fun and joyful slots such as My Bingo Hall, Bouncy Balls 2 and Fluffy Favourites to name a few.

This is why Crystal Furnace is such a shocking departure for them as the visuals are dark, whilst the slot is set in a blacksmith's place of business.

Playing on 5-reels with 10 paylines, this low volatility slot focuses on respins and expanding wilds leading to wins of up to 3,209x the stake!


Unlike most other Eyecon slots, Crystal Furnace features a dark colour palette of dark browns, reds and even blacks. The only light colours on the reels are from the gems and diamonds that appear on the reels.

As the reels spin, there are coals at the bottom of the screen that lights up and animates during each spin. This is a cool attention to detail that is definitely appreciated.

In terms of sounds, there's not a lot going on in the slot aside from ambient noises of pick-axes and a soft violin playing in the distance. It's not in your face and is appreciated for the subtleness.


Crystal Furnace is as simple as it comes as there are only 5-reels with 10 paylines. The only feature in this slot is the expanding wild that respins.

At the bottom of the screen, players will find the spin button and bet level button. There is a menu button at the bottom of the screen that features the sound settings as well as the paytable.

Win Potential

Eyecon is sadly notorious for some poor win potentials, but Crystal Furnace is refreshing in that aspect. The RTP is 96.56% which is over the average and higher than most Eyecon slots.

As a low volatility slot, players can expect frequent payouts but these amounts will be quite low. However, there is a maximum win of up to 3,209x the stake which is impressive for a low volatility slot and can be achieved through the respin mechanic.

Our Verdict

There's no doubt that Crystal Furnance is a simple slot but the developers have worked to make it a great slot. Whilst, there is only one feature in this slot, the feature is quite rewarding and can deliver some thrilling moments.

It's rare to find a low volatility slot and even one that has such a decent maximum win and respectable RTP. Crystal Furnace is perfect for casual slot players who want something that's easy to pick up and play.
