Joker Gems Slot Game Review

Joker symbols and gems are two of the most iconic and popular symbols you’ll find in slot games, and so you could be forgiven for assuming that Joker Gems will have a rather generic look to it, but what ELK Studios have managed to achieve with the concept is actually pretty surprising.

Set in space with a robotic Joker as your companion, the visuals are out of this world, but are the prizes similarly cosmic or will you be left on Earth? Let’s take a look in our Joker Gems slot game review.


We had expected ELK Studios to play this one safe with its visuals and settle for well established symbols to bring this slot to life, but to be fair to them they went for something a little left field in Joker Gems. The background to this slot sets it firmly in space, with a pretty gas nebula filling the field of view in a variety of colours, speckled with stars that shine through the dust. This is also a slot that’s not afraid to leave gaps, and you’ll see spaces where many slots would give you token very low paying symbols. This means that the rest of the symbols are valuable, and comprise shiny gems of various colours, the lucky 7 and the BAR as well as the Joker herself. Basic animations and an ethereal space soundtrack are also present to help build the atmosphere.

There are a couple of interesting mechanics at play in the Joker Gems slot game, in common with other grid slots out there. Wins are achieved by landing symbols in groups, not lines, so all you have to do is have three or more symbols touching each other to generate a win. Even better, when you do manage to land a winning combo, you’ll get free re-spins for as long as you can keep adding to your little group. That’s what the empty spaces are for, and they can soon fill with larger and larger groups of symbols if you’re lucky. At the top end of the prize bracket you can win 700x your stake by landing 16 joker symbols on the screen at once, though there are bigger payouts to be found in the bonuses, resulting in an overall RTP of 96.3%

Joker Gems Bonuses

The really big payouts in Joker Gems take the form of big jackpots that you get for landing symbols in specific patterns. Filling the outer border of the screen with the same symbol pays £/€/$20,000 your stake, while filling the internal symbols within the grid grants you £/€/$10,000. The maximum prize is a whopping £/€/$50,000, achieved by filling the reels entirely with one symbol! There’s also a helpful little beam of light which sometimes zaps the reels and creates a group of five identical symbols, but those patterns are the thing that will make you rich in the end!

Casino77 Verdict

Joker Gems is a surprising slot that manages to spring a few mechanics that you might not expect. It looks different for a start, with the space theme coming as a bit of a surprise to players, while the group winning mechanic and those really big top prizes are both tempting inducements to play!
