Crystal Forest

Crystal Forest is an enchanting online slot by WMS that’s available in two different formats – the original game and Crystal Forest HD. However, the only difference with the HD version is that it uses new, high-definition graphics to improve the visual performance. So, no matter which title you opt for, the rules and the special features remain the same.

WMS is a long-established online slot manufacturer that has produced a myriad of hit titles over the years, including Zeus 1000, Amazon Queen, Spartacus: Gladiator of Rome, The Wizard of Oz, and Montezuma.

In its Crystal Forest online slot, WMS has chosen to use a magical theme, and if you particularly enjoy games of this genre, we can highly recommend a spin or two on Pixies of the Forest by IGT.

A stand-out performance is ensured through the use of Cascading Reels, a feature which removes winning symbols from the screen and replaces them with new ones so that you can potentially create further winning combinations on the same spin.

There’s also a wild symbol that can land stacked on the reels to boost your winning potential, and a Free Games Feature which is triggered by achieving consecutive winning combinations rather than via a scatter symbol. And, we’re sure you’ll be delighted to hear that the Free Games Feature has a chance of offering you as many as fifty free spins before it even gets underway!

You can start playing this enchanting online slot for just 25p per spin, but if you wish to spend more in order to qualifying for bigger cash prizes, you can spend up to £125 per spin.


Crystal Forest invites you to enter a clearing in a magical forest where an ethereal white light hits the centre of the ground. Toadstools are dotted on the ground, and fireflies hover among the ancient trees.

The reel set sits in the centre of the screen, and as it’s semi-transparent, you can continue to enjoy the forest view while you’re playing.

The paytable symbols that can help you win cash prizes in Crystal Forest include lanterns, white rabbits, wildflowers, magical potions, wands, ladybirds, mushrooms, fairies, unicorns, and butterflies.

To create a winning combination, you need three or more identical symbols to appear on adjacent reels from left-to-right, beginning with the leftmost reel, although the wild symbol can be used to replace other symbols in the game.

With each consecutive win, the Free Plays meter to the left of the reels rises.

The game uses five reels, twenty-five fixed paylines, and three rows of symbols, and you can either play it manually using the circular white spin button or set it up to play automatically for a fixed number of spins using the Auto Play feature.

You can change your total bet between spins using the Bet/Line buttons, which allow for a minimum value of 0.01 and a maximum of 5.00.

The menu button at the bottom-left of the screen brings up the rules and paytable.

Wild Symbol

The Crystal Forest online slot uses an image of the forest with the word “WILD” written across it in yellow for its wild symbol, and the good news is, it can help you achieve more frequent wins by substituting for any other symbol on Reels 2, 3, 4, and 5. As it can also land partially or fully stacked, it’s more powerful than many wild symbols that you tend to encounter while playing online slot games.

Scatter Symbol

There is no scatter symbol in the Crystal Forest online slot as the Free Games Bonus is triggered via the Cascading Reels Feature.

Bonus Round

One of the most exciting elements of Crystal Forest is the Cascading Reels Feature, which is activated following any win. After awarding your prize, the symbols that are used in the winning combination disappear, letting the remaining symbols on the reels drop and new ones cascade down from above the reels. Any new wins that are formed result in you receiving more cash rewards, and the process continues until no new wins can be created.

We’ve not finished yet, though, as there’s still the matter of the Free Games Bonus, and you can unlock it by getting four or more consecutive cascades.

Four back-to-back wins get you four free spins; five consecutive wins get you ten free spins; six consecutive wins get you fifteen free games; seven back-to-back wins get you twenty-five free games, and eight or more back-to-back wins get you fifty free spins.

The Free Games Bonus uses an alternate set of reels, although the winning combinations are formed the same way as in the base game. You can earn additional free games by getting four or more consecutive cascades.

Finally, if you fail to succeed in triggering the Free Games Bonus through the Cascading Reels Feature, it can be awarded at random at the end of any non-winning spin.
