Playing Cool Jewels

First things first, let’s take a look at how to play Cool Jewels. This is not your typical slot game.

Instead of matching symbols across the reels, left to right, the Cool Jewels casino game is made up of a 6×6 grid. Therefore, you can make winning paylines by matching symbols horizontally, vertically and diagonally. So, straight away, this game is not typical of a standard slot.

Furthermore, as you make winning paylines, these symbols will be destroyed and disappear. They will then be replaced with a new set of jewels. So, this cascading real feature is another quirky and unique element to this game.

Aside from the standard symbols, you also have quite a few special images as well. For example, there are 4 different Wilds and each one has a slightly different function.

You also have a 10x multiplier in the base game, as well as the Cool Jewels bonus symbol that leads to free spins.

Finally, you’ll notice that you have 2 metres either side of the grid. To the left, you find the ‘pay per symbol metre’ and to the right you have your ‘free games’ metre.

So, to summarise, this game has a lot going on. But there are plenty of chances to make those winning combos and land yourself a big win. But, if you prefer to try this game for free, to get a feel for it, then check out the Cool Jewels demo version. Which you can find at some of the leading UK slots sites that we list.

Paylines and Paytable

WMS’s Cool Jewels requires you to make winning paylines by matching 4 or more of the same symbol.

But, because you can create the paylines horizontally, vertically and diagonally, it’s actually quite hard to calculate exactly how many paylines are on offer. Plus, you also have wilds that appear too. These can create pairs and groups, which will extend your payline out even further.

Again, another unusual feature of this game is that all of the gems in the base game are worth the same amount. Whereas, with most other slots, they vary in value.

Finally, with the addition of a 10x multiplier and bonus symbol, you have plenty of chances to create lots of lovely paylines.

Wager limits on Cool Jewels

The minimum wager on this game is just 50p. So this title is suitable for people who like to start off small. However, this game isn’t great for super low bettors, who like to start off with a penny or two per spin.

At the other end of the scale, the maximum wager on this game is £200. And the Cool Jewels jackpot is a massive £250,000.

To place your bets, look to the left-hand side of the game grid. You’ll find the ‘total bet’ and ‘bet multiplier’ buttons, which makes it easy to change the amount you want to wager. You’ll also notice that the ‘pay per symbol’ metre will change as you increase your bet. So that you can see how much you can potentially win if you can create a winning pay line.

What’s Cool Jewels like to play?

There is certainly plenty going on in this title. And even the most seasoned slots player will take a moment or two to adjust to this one-of-a-kind game. But, it’s still perfectly possible to become a Cool Jewels winner with a bit of luck and patience.

So, with that in mind, let’s take a look at the theme, graphics and symbols that make up this wonderfully individual game.

Theme and Graphics

With a theme of jewels and ice, it’s not surprising that most of the graphics are centred around jewels and ice!

This game has a beautiful, frosty backdrop of white and blue, with a purple game grid and lots of beautiful jewels. While not as sparkly as some other jewel-based games, the symbols are nicely done. And, in particular, the wilds explode and shoot out lightning across the screen, which makes for a very exhilarating experience.

Also, the soundtrack ties in nicely to the overall theme. And you also have your ‘pay per symbol’ and ‘free games’ metres on either side. Both of which help you understand your progress as you’re playing.

Finally, we also like that there is a small screen to the left that is constantly changing and giving you instructions on how to use your wilds and the other special features of this game.

Finally, if you want to have a thorough breakdown of this game and its functions, you can click on the paytable icon at the bottom left-hand corner.

All in all, the Cool Jewels slots game is very nicely made indeed. And it will stick in your mind, due to the fun theme and colourful, vibrant graphics.

Symbols in Cool Jewels

Now it’s time to take a look at the symbols in Cool Jewels slot:

  • They are 8 different jewel symbols, which all have the same value in the base game
  • Then you also have four different wilds. These are called the shocking, unstable, shattering and persistent wild. And these appear on reels 2 to 5 only. Plus, they explode in bright colours on the grid when you match them together. These wilds have the capacity to extend your paylines greatly

Moving on it to the special symbols:

  • You also have a 10x multiplier which can appear in the base game
  • The other special symbol is the Cool Jewels Bonus symbol. If you can destroy 4 or more of these in the base game, then you can go to the free spins round

Cool Jewels Features

As we’ve seen, there are lots of extras in this game which make it extremely fun to play. And the Cool Jewels slot machine gives you lots of chances to create winning paylines.

That said, there isn’t a separate bonus game. Which left us a little disappointed. But that is a free spins round, where you can win up to 20 bonus spins.

So, let’s take a look at some of the special features in this game in a little more detail.

Bonus games

While there isn’t a dedicated bonus round, that is a free spins game. And, because you can pick up multipliers in the base game, WMS didn’t feel the need to create an added bonus game. We assume because there’s so much going on in the base game. Still, a bonus game would have added a little extra oomph, in our opinion.

Free spins games

The CoolJewels bonus symbol is the key to the free spins round. If you can destroy 4 or more of these symbols in the base game, you’ll be allocated some free spins.

For example, if you find 4 bonus symbols, then you can look forward to 8 free spins. But, if you can land yourself 7 bonus symbols, then you can snap up 20 free spins.

Furthermore, if you find an additional bonus symbols in the free spins round, you get a further 5 free spins.

Cool Jewels free spins offers

This game is super popular with fans and therefore you can find CoolJewels at many of the best online casinos in the UK.

So, keep your eyes peeled for a great free spins no deposit bonus at these sites. A no deposit bonus is when you do not have to pay into the casino in order to receive your deal.

Therefore, you could walk away with a handful of free spins to use on this slot, by signing up to a great new online casino that carries this game.

Progressive jackpots

Cool Jewels jackpot winners can potentially bag themselves a top prize of up to £250,000. But it may surprise you to learn that this is not a progressive jackpot title.

While progressive jackpots games are all the rage, the minimum bet tends to be a lot higher than with other slots, because you are paying into a prize pool.

So, given that this is not progressive game, you still have the chance to reach for an enormous jackpot prize, while still only betting a minimal amount.

Cool Jewels RTP

Cool Jewels slot RTP is 96.10%. This is in line with the average RTP for a slots game. Plus, this game offers players medium volatility. Meaning that it pays out frequently and in good amounts.

RTP refers to the amount of your stake that you should see back if you play a game for an extended period of time. Whereas volatility refers to how often a game pays out, and what kind of cash prizes you could land. And both of these are good factors to look at when considering a new slot game.

Advantages and Disadvantages

  • Huge jackpot on offer
  • Great graphics and cool theme
  • Free spins and 4 different wilds
  • Well organised and fast-paced game
  • Quite complex
  • Lacks bonus game

Our rating of Cool Jewels

In summary, the Cool Jewels slot UK is a fast-paced, fun and light-hearted adventure game. We love a jewel-based slot. And with so many added features, the Cool Jewels game stands out above many other popular gem-inspired titles.

It’s a shame that there isn’t a bonus game. But, with a fantastic free spins round, multipliers and 4 different types of wild, this game offers players some incredible entertainment and a very good chance to walk away with a huge cash prize.
