Play Cool Jewels

Cool Jewels slot machine has six reels. The symbols are also located in six rows at the screen. Consequently, it can fit thirty six elements in the same time.

This game has numerous special symbols except of the standard images. It is also provided with various prize functions, including extra multiplied of payoffs, prize spins and etc. All of them are carefully described in the following article.

It is possible to play this slot machine by fifty divisible bet. It can vary in range from fifty cents to two hundred euro.

There are no active lines in this model. The paid combinations are formed of four and more similar symbols (now we are talking about the standard elements). They have to form a continuous chain jointing each other vertically or horizontally. Later the symbols which form winning combinations are burst, while new drop out at their places. This process continues until new combinations appear at the screen (up to thirty updates in the same round).

Well, now about the system of calculation the payoffs. It is interesting that Cool Jewels slot machine doesn't have any indexes, which could be used for calculation the winning by the combinations. Instead of them you can see the special scale with points at right from the screen (which reminds a thermometer). There are from six to fifteen points in each of the scales. When a combination is formed, the symbols included into it fill the scale - one point for each of the symbols.

While the level is situated in the first part, an amount of the payoff for each of the symbols in the combination is 1/50 of the total bet. As soon as the level rises up to the second scale, an amount of the payoff increases to 2/50 of the bet. The the top scale, where there are no points, an amount of the winning is calculated by multiplying each of the elements of the combination by the total bet staked per spin.

In case of several winning combinations in the same round, payoffs by them are calculated in the following order: first from down to up and then from left to right. The gambling feature is not provided by the rules, that’s why the total payoff is immediately transferred to the player’s account by the end of the round.

Please read about the symbols which act by other rules in the following paragraph.

According to the official information provided by the producer, the theoretical cash back index of Cool Jewels slot machine is 96,1%.

The basic gaming symbols, which you can see at the screen of Cool Jewels slot machine, are images of gems of different forms and colors. They act by the general rules making combinations and bursting after it.

The part of the special symbols is played by the following elements: Shocking Wild (a green star), Unstable Wild (an eight pointed rose star), Shattering Wild (a yellow star), Persisting Wild (an eight pointer yellow star), Premium 10x (a diamond), Bonus (a logo of Cool Jewels), Green Watermark (a half-transparent Wild capture), Pink Watermark (a half-transparent image of a bomb with a wick) and Blue Watermark (a half-transparent 10x capture).

We would like to talk more about its functions:

  • Shocking Wild appears at all the reels from the second to the fifth. It replaces other standard symbols. When it is activated in a combination, it bursts the icons at the diagonal lines.
  • Unstable Wild drops out only at the four central reels. It can take places of other basic elements in the combinations. In such cases it bursts destroying all symbols around it.
  • Shattering Wild can be found at the second, the third, the fourth and the fifth reels. It is able to replace the missed standard symbols in the combinations. Then it bursts the symbols situated at the horizontal line and the reel where it dropped.
  • 10x - makes difference to the rest symbols by increased payoffs by combinations. They are taken in account after the rest combinations.
  • Bonus triggers the round of free spins. Four and more bonus symbols bursted in result of another spin give a right for participation in at least eight free spins. An amount of the bet remains the same here. However, it is staked by the casino instead of the customer. An alternative set of reels is in force during this round. Free spins can be prolonged. Please read more about it in the rules of the game.

Other symbols appear at the screen in result of interaction with Wild symbols, which were mentioned above. It happens when they drop out next to each other at the reels.

  • Persisting Wild also can replace other basic symbols in the combinations. It appears when two similar Shocking Wilds, Unstable Wilds or Shattering Wilds are situated next to each other. New Wild would stay at the screen until it goes down to the bottom line. It also loses its force in case no new combinations are formed and a new spin is getting started.
  • Pink Watermark appears when Unstable Wild and Shattering Wild drop out next to each other. These symbols fill all positions covered by Unstable Wild. In the following update the symbols which drop out at these cells (except of active Wilds) would be bursted.
  • Blue Watermark can be seen after Shattering Wild and Shocking Wild drop out next to each other. These symbols would be situated at the positions activated by Shattering Wild. In the following update the combinations formed in these cells would be paid out by x10 multiplier.
  • Green Watermark drops out when Unstable Wild and Shocking Wild appear next to each other at the reels. They would fill all the cells activated by Shocking Wild. In the following update all the symbols which you can see here would turn into Wilds which replace other elements.
