Joker Gems Slot Review

The Joker Gems game can be found at casinos offering Elk Studios software. Elk Studios are a small but quickly growing casino software developer primarily focusing on the mobile market. At the present time they only offer slots games. Players should be aware that this software provider includes ‘betting strategies’ as an automated feature. These should be avoided. They offer no mathematical gain to the player and increase the risk of large losses in comparison to your bankroll. As a standard Elk Studios do publish the RTP/House Edge information for their slots games within their game paytable. As such we can say that the House Edge of Joker Gems is 3.7%.

You play Joker Gems on a 5x5 grid, using combinations of symbols instead of paylines to generate your wins. Clusters of 3 or more symbols, excluding diagonals, will trigger wins.

Special Symbols

There are no Wilds, Scatters or Bonus symbols in the game, making the “Joker” the most valuable symbol.

The “Joker” symbol starts with a coin value of 15 for a combination of 3 in a cluster and rises all the way to a coin value of 700 for a combination of 16.

Bonus Features

Jackpots – There are 3 different Jackpots available. To win the 10,000 coin Jackpot you need to land a square of identical symbols in the centre of the grid. It must be 3x3, with no symbols touching the outer layer of symbols. To win the 20,000 coin jackpot you need to fill every square on the outer layer of the grid with identical symbols. To win the 50,000 coin jackpot you need to fill every single square on the grid with identical symbols.

Light Chaser – A “Light Chaser” will randomly appear between spins and will create a cluster of 4 to 5 matching symbols, which results in a win when the “Light Chaser” stops.

Re-Spins – Any winning combination of three or more symbols will automatically trigger a re-spin at the same bet value as the original spin. When this happens, the winning symbols will stick in place, whilst all the others are replaced.


“Joker Gems” is a decent looking slots game that takes the tradition of Gems and Jokers and adds a modern twist by placing the grid in amongst the cosmos. The symbols look good and the features that we have are interesting and engaging. The lack of Wilds, Scatters and Bonus symbols is disappointing, as is the lack of a bonus game. However, the biggest disappointment are the “Advanced Betting Stategies” that are built into this game and sold as an advantageous game feature, when these strategies offer the player no improvement over flat betting. The reality is that if you increase your bet, you’re more likely to lose money than you are to make any. This is poor practice, that drags everything positive about the game down. We would be highly critical of any website offering bogus betting strategies so a game developer doing this is even more problematic for us. Without this feature this game would naturally rate significantly higher.
