Cool Jewels is an online slot by WMS that is taking advantage of the popularity of mobile games like Candy Crush
The bonus round consists of a super bouncy free spin bonus, with a terrifically catchy Japanese tune in the background. In no time, you will be swinging and dancing along, all the while raking in bucket loads of credits.
Cool Jewels is one of our favourite online slots, which we play at least once a week. You know, to get in a happy mood, if we weren’t there already. And to fatten our wallet every once in a while.

What are the variance and the payout rate of Cool Jewels?
Cool Jewels has a medium variance. This game can pay out enormous amounts of money, especially in the bonus game. That has everything to do with the exploding symbols mechanism: winning combinations disappear and make room for new ones.
But all symbols keep increasing in value as more and more winning combinations occur. A nice series with winning combinations can, therefore, deliver hugely.
The payout rate of Cool Jewels is 96.1%. Not fabulous, but certainly not bad.

How does the Cool Jewels slot work?
The Cool Jewels slots has no paylines and is played on a large field of 6 x 6 symbols. When combinations of 4 or more of the same symbols drop, you get a prize. The symbols explode and make room for new ones, for new winning combinations to be possibly created. This process repeats itself just until there are no more winning combinations created.
The value of the symbols is determined by how high the level is of a gauge located on the left-hand side of your screen. With the minimum bet of $€ 0.50 per spin, every symbol will be valued at $€ 0.01 at the start of a turn, but that can increase up to $€ 0.50 per symbol.
The diamonds are always very interesting because they are valued at 10 x, all the time.
The wild symbols play an essential part in Cool Jewels. These replace all other symbols but also make extra symbols disappear from the screen. Besides that, you also free up additional extra features when two wild symbols drop beside each other (and make a winning combination).
This way, you can create sticky wilds (up to 6 turns), extra wilds, multipliers up to 10 x or a whole block of wilds. Perhaps it all sounds a bit complicated, but you will know exactly how it works once you figure it out.

The Free Spin Bonus: extra wilds and big wins
If you save up 4 or more Cool Jewels symbols, you win the free spin bonus. 4 Cool Jewels symbols will get you 8 free spins, but you can save up a whole lot more than that. And during the free spin bonus, you can win extra free spins as well.
During the bonus round, more wilds will hit the reels then during the primary game, which translates into more payouts and more special wild combinations. Sometimes you can make a very long and lucrative series that, because of the many extra wilds, seem endless- now that is enjoyment! The super catchy tune you hear during the free spins cranks up the party atmosphere even more.
And at the end, when Cool Jewels addresses you with the words “You are beautiful” or “You are fantastic”, our heart does melt a little bit with all this beauty.

Our verdict on the Cool Jewels video slot?
It must be clear: we are in love with Cool Jewels. It does take a while before you figure out everything that is happening on the screen, and the bonus round sometimes takes ages to win.
This slot is colourful, playful and unique, all at the same time.
We love it.

The wagering requirements on all deposit bonuses are quite decent: 40 x the bonus amount. Don’t forget: If you want to avoid these bonus wagering requirements, you can always choose to decline any bonus. The max bet per spin with bonus money is unusually high at $15 per spin.
