Joker Gems Online Slot Review

Joker Gems is an online, iOS, and Android optimized slot from Elk Studios which you can play for free on this page. Bet between 0.20 and 100.00 per spin at a recommended casino and you collect wins with clusters of symbols across a 5x5 grid. Free respins can see these clusters grow in size, and there are a couple of randomly triggered features, with guaranteed payouts.

A beam of light can create winning clusters, and you can win one of three jackpots in any spin. There’s up to 50,000.00 to claim from a jackpot, or a vast 70,000.00 when the highest paying symbols fill the grid.

Joker Gems has become hugely successful. It looks highly impressive, with an outer space theme, colorful gemstones, and a Joker character on the reels. The game is straightforward enough for anyone who isn’t used to slots but has all the exciting gameplay and features that experienced real cash players are looking for.

Joker Gems Slot Game Setup & Controls

The 5x5 grid sits in front of a nebula in deep space. Look to the left the grid, to the graphic of coins, which you click to adjust your bet level. It’s very easy, and the wide range of potential stakes covers most budgets.

Other buttons activate an automatic spins mode, and the ‘Rules’ tab opens up the paytable, which lists how much you win from each cluster. Unlike most slots, where you need to land matching symbols on adjacent reels, with Joker Gems, you want to see symbols grouped together in clusters of 3 or more. Larger clusters pay out bigger prizes, with the Jester returning a win of 700x your bet.

Taken as a long-term average, it pays back 96.3% of stakes as winnings. As online iOS, and Android-compatible casinos cost less to run, payouts tend to be higher than those you would be used to if you have only played at land-based sites.

A great thing about ELK Studios slots, is the option to set up different betting strategies. The Optimizer strategy, for example, always stakes a set percentage of your bankroll on each spin, while the Jumper raises stakes on a win.

Joker Gems Mobile Slot

Of course, physical casinos can’t match the convenience of playing online mobile slots from home or out and about. Joker Gems works just as well across all devices, whether it's your PC or Apple or Android phone or tablet, with just a couple of layout changes to suit the different screen sizes.

Joker Gems Slot Gameplay Features

This is a medium to high variance slot, so you won’t land a win in every spin, but payouts can be quite high to make up for this. The gems will appear in clusters more often than the top-paying BAR, Seven, and Jester symbols, but that only makes it more exciting when the top symbols land in place.

Joker Gems Slot Respins, Jackpots & Other Features

On any win, the symbols in the winning cluster lock in position, as the rest of the reels respin for free. If that creates a bigger cluster, the respins repeat, and so on, until no new wins are seen. It’s a fantastic feature that can lead to huge clusters, free spins and some great rewards.

The random Light Chaser feature sees a strange beam of cosmic energy zap across the reels, leaving a guaranteed winning cluster of 4 or 5 matching symbols in its wake.

If you fill the middle 9 symbol positions with a cluster, you win the 10,000.00 fixed jackpot prize. Matching symbols right around the edges trigger payment of the 20,000.00 jackpot and a vast 50,000.00 is yours for filling all 25 spots with the same symbol.

Max Payouts From Joker Gems

These non-progressive jackpot pay the same amounts at any stakes. But at the highest bet levels, you can win even more from the Jester, who is worth a maximum of 70,000.00 when you have 100.00 wagered on the spin.

Joker Gems Pros & Cons

If you like slots with a strong theme, such as the popular ELK Studio releases Taco Brothers, or Sam On The Beach, then the simple jewels and outer space backdrop featured here might lack a little atmosphere. The Joker looks a little creepy as well, so if you have a phobia of clowns, then steer clear.

Otherwise, Joker Gems is an excellent slot, with some great winning potential. We love the respins, Light Chaser and the chance to collect jackpots in any round.
