Cool Jewels Review

WMS are a rather low-key studio, but they have launched some interesting slots over the years, some of which are still interesting to this day. Cool Jewels belongs to that category, which is why we’ve decided to review it in full. The one thing that will strike you right away is the large playing field with 6 reels and 6 rows. Moreover, there are no paylines. Instead, Cool Jewels is one of the early Cluster Pays slots!

The Cool Jewels slot was first launched way back in 2014 and it looked rather good back then. We now have different standards to go by, however. It therefore has to be said that the visuals aren’t quite up to scratch anymore. That doesn’t mean they are bad. It just means that you can’t expect the same level of detail and fireworks as you can from modern online slots. And yet, Cool Jewels still looks good in its own right. Its symbols are neat and feature all sorts of jewels!

The mathematical model of Cool Jewels boasts a medium volatility level and an unknown jackpot. You can win big during certain features, but the official data sheet offers no specific theoretical limits. The betting range is wide, meanwhile. Low rollers can jump into action for as little as £0.50 per spin. The maximum that you can play for, on the other hand, is £200. The theoretical RTP of the game is then 96.10%, so slightly above average.

What Symbols Are There?

Payouts don’t work as per usual in Cool Jewels. Instead, the slot combines Cluster Pays with Cascades in a strangely innovative way that isn’t used all that often. Winning combinations that you get are automatically removed from the board, while new symbols drop in to fall the empty spaces. This can lead to new wins and new Cascades. This process always goes on until you fail to find a new winning combination (or until you get 30 Cascades in total).

The symbols don’t have any payouts of their own, either. Instead, they fill the Pay Per Symbol Meter that has 12 sections in total, each of which comes with a certain number of slices that you have to fill before you can move on.

Each symbol that you remove pays out according to the meter and there are many special symbols as well. We’ll describe them and their functions in the next section.

Cool Jewels Slot Features

Cool Jewels is absolutely packed with gameplay features and special symbols. There are four Wilds in total, for example. There are Unstable Wilds, Shattering Wilds, Shocking Wilds and Persisting Wilds, with different behaviors and effects. These symbols can also work together with certain Watermark symbols that appear after you use a combination of Wild symbols. These then affect what happens after the Wild symbols have already left – for example, they can destroy symbols on them to give you another Cascade free of charge.

Next, there are the all-important Premium 10x symbols that pay 10x the usual awarded value. These are always evaluated after all the other symbols have contributed, so you’ll always get the most out of them.

If you get 4 or more Bonus symbols destroyed in a single spin sequence, you’ll trigger the Free Games Bonus. Depending on how many symbols you destroy, you can get up to 20 free spins at once, that’s for 7 or more Bonus symbols destroyed. During free spins, there’s a different set of reels and you can get more free spins as well. The numerous interactions can happen as well, so it’s a bonanza of wins altogether!

The bottom line is that Cool Jewels is one of the most complex online slots on the market even now. There are so many possible interactions that you will have to spend long hours with the slot to uncover them all. That’s so rare in online slot gaming that you should give Cool Jewels a shot simply because of this bit!

What Is the Jackpot (Max Win)?

Cool Jewels doesn’t offer any fixed or progressive jackpot. The official data sheet offers no theoretical jackpot either, so it’s quite hard to say how much you can win exactly. Since you can get as many as 30 Cascades at once, the limit is definitely rather high. However, you’d need to get insanely lucky to get a huge win, as is always the case. Regular – and pretty decent – wins come often enough for it all to feel fair, however.

SlotCatalog Verdict

Cool Jewels is an early example of how interesting Cluster Pays slots with Cascades can be. Even though it’s several years old at this point, it’s still a complex game that surpasses many new releases in a lot of regards. If you like deep online slots that are absolutely packed with gameplay features, you’ll surely fall in love with this one. The wins can be high and spins can even take minutes if you get lucky – how about that!

The only objective minus are the somewhat outdated visuals, but that’s a small price to pay for such a fun and engaging experience. And they aren’t too harsh, either – there are even quite a few animations to be enjoyed!


  • Pleasantly deep and complex
  • Some spins can go on seemingly forever
  • Absolutely packed with gameplay features


  • Graphics a bit outdated by now
  • Can be confusing at first
