Crystal Furnace - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction

Don’t be deceived. The five reels and ten paylines of the Eyecon slot Crystal Furnace may look simple, but they don’t tell the whole story. The paylines are adjustable - you can change them yourselves - and even more excitingly they pay both ways. Everything about this slot, from its vivid graphics to the thrilling expanding wild re-spin feature, elevates it above your standard gem-themed game. Don’t believe us? Read the rest of our in-depth Crystal Furnace slot review.

Theme, Graphics & Soundtrack

This is one of those video slots that makes its theme very clear in the title. There are crystals, and they’re in a furnace. Now gems are pretty common in a slot game, but they tend towards generic plain backgrounds or the occasional sci-fi setting. Crystal Furnace is something quite different, buried in a world of smouldering coal and sparking metal. The gems themselves, in a variety of colours, are rough-hewn as if they haven’t been cut yet.

It’s a heavy sort of slot, all earth and fire, dramatic music interspersed with the clink of pickaxes and the crash of crumbling rocks. It gets even more energetic if you’re lucky enough to score a winning spin. A definite contrast to the blue skies and fluffy main character of the Fat Rabbit slot.

Crystal Furnace RTP and Variance

Many casinos will let you play no deposit slots for free to encourage you deeper into their world. If you’re playing a demo here on Slots Temple, there’s never any real money involved. Still, part of the satisfaction of playing a slot is being able to hit some wins. When you see the Crystal Furnace online slot, with its pretty high 96.56% and the low variance that helps keep wins reasonably frequent, it can make things seem much more exciting.

How to Play Crystal Furnace

Are you ready to chisel out some gems?

1. Video slots have some commonalities of design, so if you’ve played any slot game before you’ll have an idea where you’re looking. If not, start with the menu, where you’ll find the rules and paytable.
2. Also in the menu, which you’ll find in the bottom right corner, there’s a sound icon. You can switch background sounds on/off or slide the volume meter. Just above sound is autoplay, but you don’t want that yet.
3. When you return to the main screen you can adjust your bet by using the stack of coins symbol. Here you’re also able to adjust your payline.
4. Even with free no deposit slots, get yourself into good habits and pick a sensible bet based on your available balance and what you can afford to lose.
5. Make sure your budget is in place before you start. Responsible play is more fun.
6. Like you’d expect, the biggest button is spin. Above it is another link to autoplay, which allows between 5 and 100 automatic spins but doesn’t allow you to include any limits as alternative stopping points.
7. Don’t forget to take regular breaks. Never chase losses.

When the fun stops, stop.

Crystal Furnace Bonus Features 

When you’re choosing your favourite Eyecon slots, one factor you’ll definitely want to consider is any bonus features. Crystal Furnace may only have one, but it’s very exciting:

Expanding Wild Re-Spin

An expanding wild does what it says: it’s a wild that grows to fill more than one position and improves your chances of a line. This happens any time a wild appears on the second, third or fourth reels in Crystal Furnace. What makes it different from any other slot game is that it doesn’t just fill the entire reel - it triggers a series of up to three re-spins with that wild held in place. That’s even more winning chances.

Crystal Furnace Review

There may be lots of video slots that prominently feature gems, but very few of them look anything like Crystal Furnace. It’s not just distinctive in its graphics: it also spices up its expanding wilds with re-spins to make a thrilling game. This is a great addition to the ranks of our no deposit slots.
