Crystal Furnace is the perfect slot game for those who prefer simple gameplay, little wins, and low stakes. The game certainly gets top marks for stunning audiovisuals, but if you’re on the hunt for thrilling bonus features and innovative extras, this is not the online slot for you. The lack of multipliers, bonus games, or free spins is another potential dealbreaker. Still, the Expanding Wild Re-Spins feature adds some spice to the game, with a max win of up 150x your bet on offer. Overall, a simple and safe slot game, but a bit dull for a seasoned player.

Expanding Wild Re-Spin Bonus

The Expanding Wild Re-Spin Bonus will see from one up to three reels covered in the mystical hammer Wild symbol(s), which will lock into place for a re-spin. If more Hammer Wilds land on the reels during this re-spin, then another re-spin will instantly take place. You can trigger a maximum of three re-spins during this bonus feature.

These symbols can only land on the middle three reels, and they substitute for all other symbols to trigger wins.

Our Verdict
While the Expanding Wild Re-Spin Bonus comes quite frequent and can be quite generous, the max win is very low and it's disappointing that there are no bonus games within this slot.

Crystal Furnace Slot RTP & Volatility


Variable RTP





The Crystal Furnace slot has a Return to Player (RTP) of 96.56%, which is very slightly above the industry average of 96%. It is considered a low volatility slot game, which means that while wins may come more often, they will likely be of lower value.

Our Verdict With the RTP might be slighter higher than average, and volatility being low, you should expect lots of little frequent wins. I think this is good for those who enjoy playing low stakes.

Crystal Furnace Slot Graphics & Audio


The graphics are nothing too much to shout about, but they are good enough. The visuals remain to be quite basic, but they do the job. When playing this slot you'll have the smoking background of a lit up furnace with the gems and jewels in the reels.

The sound is a rather mystical and eerie sound, like an empty furnace that's been vacant for centuries. When you achieve a win, expect to hear a video-game-style win sound.

Our Verdict I think that the visuals are very basic, but they do the job in accordance to the theme. However, despite the sound matching the visuals, it was a bit boring and I think bolder sounds could be made when you achieve a win; to help that immersion.

Crystal Furnace is fully compatible with all smartphone and tablet devices, so you can take all the excitement with you wherever you go. Built using the latest HTML5 technology, it offers effortless touch control and stunning visuals, as well as flawless gameplay. There is certainly no compromise when playing on your mobile device.
