Cool Jewels – Play WMS Slot Machines Online for Free
Cool Jewels from WMS is a compelling grid-style slot with unique wild features that takes inspiration from popular arcade games.
More and more slots are taking inspiration from arcade games and stepping away from the traditional style of slot gameplay. At first, you might mistake Cool Jewels as an attempt at trend-chasing with its increasingly familiar grid format and gem theme. Upon deeper inspection, though, you’ll discover a unique slate of bonus features and remarkably player-friendly design elements. Guaranteed minimum wins, above-average RTP, and special wild symbols are more than enough reasons to try Cool Jewels.

Best features on Cool Jewels slot
Cool Jewels innovates the grid slot format with a unique, entertaining gameplay loop and great gameplay features.
- Wild gameplay: A trio of exploding wilds and special effects that stem from them keep normal gameplay interesting.
- Interwoven bonus features: Destroy bonus symbols with the exploding wilds to trigger free games.
- Guaranteed minimum wins: Triggering free games is guaranteed to pay out 10x your total bet.
How to play Cool Jewels slot for free or real money
Play Cool Jewels by setting your bet between $0.50 to $200, choosing if you want to use auto-play, and hitting the spin button. Since this is a grid-based slot, there are no pay-lines, and instead, there’s a grid where combinations of four symbols create wins. In this regard, the game is easy to play because you always know any line of four or more like symbols will win and don’t need to remember pay-lines. However, it does get a bit more complex with its bonus features. We recommend that you get accustomed to the game by trying our free demo version first, or signing up at a casino and using their casino welcome bonuses.
Cool Jewels graphics and design
Cool Jewels’ graphics get the job done, although they can’t help but look similar to every other Bejeweled-inspired game. This derivativeness aside, the symbol designs and backgrounds are colourful, detailed, and generally appealing. Likewise, the exploding wild effects are just as visually satisfying as the gameplay feature is.

How Cool Jewels’ bonus features work
Cool Jewels automatically stands out a bit thanks to playing as a grid-style slot, but that’s not all it has going for it. It makes the most of the grid format with unique bonus features that play into it perfectly.
Cascading wins
When you form winning combinations after a spin, the symbols in that combination explode and new ones cascade into place. This can result in still more winning combinations, with a theoretically limitless upper bound in place. Furthermore, cascading wins come with the benefit of activating the pay-per-symbol feature, where successive wins fill up the meter. As they fill up the meter, the value of your symbols in each win becomes more valuable. One of the best ways to get these wins going is by landing an exploding wild in a combination.
Exploding wilds
There are three different types of exploding wilds that each substitute for all basic gems to help create wins. What separates the wilds from each other is that they explode in different ways:
- Unstable wild destroys all adjacent symbols
- Shattering wild destroys symbols horizontal and vertical from the wild
- Shocking wild destroys symbols diagonal from the wild
By destroying so many extra symbols, the wilds have a powerful ability to cause new cascading wins. It’s also possible for the effects of the explosive wilds to overlap, with three different combinations that each produce three different watermarks over that space on the grid. The effects of these watermark combinations are:
- Pink watermark: Symbols on these spaces are destroyed after the win calculation in the next game, which can be just what you need to extend a cascade.
- Green watermark: The symbols function as wilds in the following game.
- Blue watermark: Any symbols destroyed on a blue watermark space award 10x current symbol value.
Free games
The exploding wilds can also destroy bonus symbols, which is how you earn free games. Destroy the following number of bonus symbols to achieve the corresponding amount of free games:
- Four bonus symbols for eight free games
- Five bonus symbols for 10 free games
- Six bonus symbols for 15 free games
- Seven bonus symbols for 20 free games
- +5 free games for every additional bonus symbol
The main interesting quality of the free games is that they freeze the pay-per-symbol amount, which means that you play with elevated winnings from the start. Furthermore, you’re guaranteed to win at least 10x your total bet during free games.

Final thoughts on Cool Jewels by WMS
You might not guess at first glance that Cool Jewels is as much of an innovator as it is, but as soon as you delve into it you come to appreciate its rich, varied gameplay from provider WMS. It can be a bit confusing at first, particularly tracking the different wilds and elemental effects, but it’s worth putting in the effort for. With more intriguing visuals and greater clarity during gameplay, Cool Jewels could have been a 9/10 or better. With these drawbacks in mind, we award it a 7/10 but recommend it nonetheless.
