Cool Jewels Slot Demo Review

If you are a fan of the newest casino games with creative designs and unique gameplay, the Cool Jewels multi line slot machine should be on your Must-Try list. It was developed by the WMS team and released in summer 2016. The game has many outstanding features, but the most important thing is hidden in its playing field. There are 6 reels and 6 rows with no winning lines, making it unique kind of slot.

It wasn`t enough for the developers to add the standard Joker and bonus spins, so they included a number of lucrative options that help gamblers win large sums (96.1% RTP). All the details are described in the Cool Jewels slots review which you should read to the end! 

How to play this slot

At first glance, a slot machine with such a layout and a set of symbols seems difficult to play. Perhaps this is the case in some games, but in this slot, it does not work. It may take a little longer for beginners than for advanced gamblers. 

The gaming slot looks like a big glacier, which is the name of the casino game. The playing field with symbols covers almost the entire monitor. The control panel is represented by several buttons fixed to the left. There you can adjust the amount of the bet: from $0.5 to $200 in each round.

The largest button triggers a single spin. Once you complete this action it will turn into Stop to stop the reels early. The autoplay option is for those of you who want to enjoy Cool Jewels slot machines visualization and profitability.

All the features of the game, payout ratios, methods of making combinations, and general rules are described in the theoretical section that opens with the corresponding button. Learn it to have more benefits during your gaming session. 

Given the unusual structure of the free Cool Jewels slot, the new way of forming combinations does not seem strange. By clicking Spin, you will receive a payout if at least one Matching Group appears on the screen. It consists of 4+ identical symbols connected vertically and/or horizontally.

Symbols and soundtrack

There is no pronounced soundtrack to complement the overall theme. Instead of it, the developers used the sounds of exploding symbols, spins, and other actions that you will perform during the game. If you want to disable/enable sound effects – go to settings.

The character set is quite extensive. You can match groups with purple, orange, blue, yellow, pink, turquoise, green, and red gems. The cost of symbols depends on how much you have filled in the Pay Per Symbol meter on the left. There is no progressive jackpot, but the winners will receive a big sum – $250,000!

The beauty is that the Cool Jewels slot explodes at its seams with bonus symbols. There are 4 Wilds (Shocking, Unstable, Shattering, Persisting), Diamond Multiplier, Bombs, and Bonus (Logo) symbols. 

Bonus options

If you’ve been looking for an abundance of bonus options, you’ve landed in the right place. The development team paid a lot of attention to this part of the Cool Jewels game:

  • Pay Per Symbol meter. On the left side, there is a meter with 12 sections that fill up when you detonate the cascading symbols. The higher the section, the more payouts you get. However, it is reset to zero when the sequence of combinations is interrupted.
  • Wilds. Depending on the selected Wild symbol, you can destroy all icons in spaces that are diagonal to its position, destroy symbols in certain directions, or remove all nearby pictures.
  • Enhancement feature. By landing horizontally in adjacent cells, Unstable and Shattering Wilds can combine to form Pink Watermark. In the next round, symbols hitting this cell will instantly explode. By combining Shocking and Unstable Wilds, you get a Green Watermark, while Shattering and Shocking Wilds form a Blue Watermark with an additional 10x multiplier.
  • Free Spins. The appearance of 4+ bonus symbols means the start of the game with free spins. They will explode after determining the number of free games you get: from 5 to 20 rounds during which you don`t bet.
  • Cascading combos. The symbols participating in the combination explode, making room for new ones, and they can again make up the prize chain.

Even though Cool Jewels casino game has no jackpot wheel, these bonus options look attractive enough, but on the other hand, you need time to see how they work. Therefore, you can play a demo slot on our website. 

Pros and cons of the slot

This slot machine deserves every minute of your time. Its built-in features are fun enough especially when characters explode, and you get rewards. Here is a complete list of the advantages/disadvantages we have found.


  • Four types of Wild.
  • Exploding symbols.
  • Additional multipliers.
  • Massive jackpot.
  • You can play for free.


  • The rules can be tricky for beginners.
  • The amount of payments depends on the Pay Per Symbol meter.

Overall, you will have a great experience on mobile and desktop devices!
