Review of Joker Gems Video Slot

Joker Gems is what could only be described as a mix of sci-fi/futuristic slot game with its stardust background and space age style music.

Elk Studios isn’t a casino game creator that we would initially think to create this genre of slot games, however with the creators and designers behind this company what we can expect is a fun and enticing game and that is exactly what Joker Gems is.

It can seem a little confusing in the beginning however as the layout isn’t the norm. There are 5 reels but the way in which they have been implemented somehow looks as though there are more, but once you fully get started in this game you will be able to catch on and spin away in no time either on your desktop computer or on a UK mobile casino.

How to play Joker Gems on UK casinos

As we mentioned upon opening Joker Gems the layout can seem a little confusing but really it is just as simple as any other slot they have previously created. Elk Studios is one of those providers who likes to look outside of the box and think of other ways in which games can be created and laid out and this is one of the many reasons we really enjoy playing and reviewing their slot games. Joker Gems is available to play on all of the best UK casinos and we will walk you through the process of getting started and the first step is to adjust your betting limits.

The minimum bet in which you can place is £0.20, and the maximum bet in which you can place is £100 so this is a good middle ground and that is another thing we really like about Elk Studios is that they provide bets for those of us who wish to lay low a little bit, but they also provide higher bets for those high rollers out there. In Joker Gems there is also the option of selecting a Betting Strategy which we will get into more below. Once you have adjusted your betting limit by pressing the coin symbol on the bottom of the screen you can get started!

Top wins in Joker Gems

Light Chaser Feature

The light chaser feature is only able to trigger at the beginning of a spin during ‘normal mode’. What happens is that a Light Chaser will randomly appear between spins creating a cluster of 4 to 5 identical symbols and this will result in a win when it stops.

If you do end up triggering a cluster created by the Light Chaser then this will be automatically applicable for entering the Bonus Mode Re-spins, meaning the Light Chaser will award you with at least one Re-spin.

Cluster Pays in Joker Gems

There are no paylines in Joker Gems and this is why they have featured Cluster Pays. In order to get a cluster pay you will need to spin and win with 3 or more identical symbols adjacent to each other and this will end up forming a winning cluster. If you formed a cluster in normal mode then it will become sticky in the game and award you with a Re-spin. These Re-spins will keep on going for as long as there is an expansion to an existing cluster or so long as there are new clusters being formed on your reels.

Three Jackpots

The most exciting in-game element has got to be the Jackpots. Joker Gems features 3 different jackpots which can be triggered when there are identical symbols filling the jackpot pattern positions. On the very right of your game screen you will be able to see the value of each jackpot and the way in which you can trigger them is by getting certain positions.

A center 3x3 reel position will give you the Bronze jackpot, surrounding 16 positions will give you the Silver jackpot, and lastly if you are lucky enough to get the whole grid filled with identical symbols you will end up triggering the Gold jackpot!

Betting Strategies

Elk Studios likes to add betting strategies into their slots quite a lot, it gives players the chance to spin without worrying about when to up their bet or when to lower their bet. We have previously seen them being used in slots such as Ivanhoe and Wild Toro. This is usually something Elk always implements in their games but there are exceptions of course. There are a total of 4 different betting strategies featured in Joker Gems and you have the choice of any one you want.

You can also switch it up mid-game if you feel as though you want to try out a different type of betting strategy so that’s always a plus!

  1. Optimizer which is when the bet level changes automatically and adapts to the selected percentage of your balance
  2. Leveller where it will raise the bet 2 levels after 5 consecutive losses and will reset automatically after a win
  3. Booster, this strategy will raise the bet 1 level after a loss until it has reached 3 levels above the base bet and will reset after a win
  4. Jumper, this strategy will raise the bet level by 1 after every winning round until it has reached 4 levels above the base bet and will automatically reset after a loss
