There are limited game features in this slot with a duplicating wild symbol the main attraction in the game. This can stand in for other symbols and copy itself across the reels for more potential wins. Apart from this another great way to boost your payouts is that the game allows winning combinations both left to right and right to left, which is a nice change from the usual left to right combination only slots.

Entering the Magical Kingdom

The kingdom of ice is displayed in the background to this slot with an atmospheric scene in a blue colour adding to the feeling of wintery cold. You will see mountains in the background to the main game and when you open the pay table an ice cave becomes the background. There are just 4 main symbols in this game which are the Ice Queen herself who acts as wild symbol, the castle, the owl and the sleigh.

It is easy to place your bets in this slot by selecting your stake from the coin buttons, which can be moved up to a max bet of 2.00 per payline. You can also opt to play your choice of paylines from the minimum of 5 up to all 20 payines. For fast-paced max betting you can choose the ‘max bet’ button, which places the maximum bet conveniently.

The Ice Cave Payouts

You can see the pay table by selecting the appropriate button to open up a new screen with an ice cave background. All the symbols and their potential rewards are revealed. The top symbol in the game is the magic castle, which can award up to 200 coins if you manage to spin 5 matching castle at the same time on the reels. After this, the sleigh symbol and the owl symbol both pay a max of 100 coins if you spin 5 icons together on a payline. Finally, you can also find an Ace, King, Queen and Jack, which are the standard lower paying symbols in slot games. The best reward from the high symbols is up to 40 coins for 5 matching symbols.

The Queen is Wild

The symbol to look out for in this free Crystal Heart slot game is the Ice Queen. This is the wild symbol so the Queen can substitute for all the other symbols in the slot to create extra potential winning combinations. The Queen symbol also has an extra power, which is to duplicate itself across the screen to the touching symbols. You could turn your screen into a multiple wild screen if you are lucky creating a huge number of extra winning chances!

Will You Risk the Gamble Game?

Crystal Heart has a special gamble feature which is a part of many Merkur slot machines. This means that after any winning spin, you are offered the chance to gamble your money to potentially double up. You need to guess the colour of the next card out of the pack. Simply select red or black and if you guess the right colour you will double your cash. However if you guess wrongly you will lose your money from that winning spin. Will you take the risk?

More Snowy Journeys

If you like the theme of Crystal Heart slot, there are many other slots with similar styles of play and game themes. For example, Cool as Ice slot is a fun game with another icy theme offering players 25 paylines, 4 free spins and up to 15x multipliers. There are expanding wilds in this game, giving a similar effect to the duplicating wilds of Crystal Heart.

An Exciting Icy Adventure with Lucrative Wilds

Crystal Heart is quite a basic slot game with just one main feature – the duplicating wilds, which offer a great way to boost your rewards. The fact you can win left to right and right to left is another good feature of this slot. The only problem is that the game lacks excitement due to the lack of bonus rounds and free spins. The animations and graphics are great and they really help to boost the enjoyment but gamblers looking for exciting bonus games might be disappointed.
