How to play Gem Crush mobile slot

Take a spin on the Gem Crush slot game, and you’ll find six reels filled with Gems waiting to award you with clusters of wins which could land you up to 4,361x your bet top win.

The Gem Crush mobile slot is a 6×6 reel Cluster Pays slot from NetEnt. This medium to high variance slot features Avalanching Wins, Wilds, Symbol Transformations, and a Free Spins Bonus with 4 special features in play, including Increasing Multipliers and Colossal 2×2 Wilds.

Being a typical Cluster Pays slot, you’ll need to find a combination of 5 or more symbols touching vertically or horizontally to create a win, and the paytable isn’t very high, which means you’ll need to find big clusters or get lucky with avalanches to get any big base game wins.

Rainbow Gems and Avalanching Wins

Typically, you’ll find lots of wins in Cluster Pays slots, but much like the Gem Crush online slot, they don’t tend to pay much, with many of the lower-paying symbols paying less than your bet back for the minimum 5 symbols needed to create a winning cluster.

Those little wins can add up thanks to the avalanching wins, which see the winning symbols removed and new symbols added to create a new winning cluster or two.

In addition to this, NetEnt has added a special Rainbow Gem symbol into the mix. This gem will upgrade any of the paying symbols for that spin, making the reels richer and hopefully helping to create a winning cluster. It doesn’t always pay off, but it’s better than having nothing.

It’s in the free spins where the Gem Crush top win and most action lies.

Gem Crush Slot Free Spins Adds More Excitement

Landing 3 bonus scatter triggers 10 free spins. These aren’t your typical free spins, as they have 4 special features added, some land on every spin, and some land randomly.

You’ve got the Rainbow Gem, which, much like the base game, can randomly land and transform a symbol, but this time, the transformed symbols are transformed for the rest of the spins, helping create bigger wins.

You’ll also find a win multiplier which decreases on every spin or randomly when the XStrike feature triggers, as well as a Colossal 2×2 Wild symbol landing on every spin.

All of these bonus features combine to help provide bigger free spin wins. You might not win huge sums here, but at least if you are lucky enough to trigger them, you can find some more excitement, something that the base game lacks.

Similar Slots: Try the Lost Relics 2 slot also by NetEnt or perhaps the Rock Star Santa MultiMax slot for a festive treat.

Gem Crush Review Conclusion

Is the NetEnt Gem Crush slot on the mobile original? Not really. We've seen many gem-based cluster pay slots online in recent years. That's not to say this is a bad game; the wins are frequent, if not extremely thrilling, and if you land the free spins early, you might enjoy this slot for a few more real money spins.

The combination of the 2x2 Wild, Rainbow Gems, increasing Multipliers and random XStrike feature makes this slot.

The base game is sometimes a little boring and doesn't pay much unless you're lucky enough to land big clusters or a decent amount of consecutive avalanches, similar to other mobile slots.

Overall, Gem Crush is a good-looking slot with a familiar theme and a great free spins bonus feature. Take it for a spin at one of our best NetEnt casinos and see if you can crush these games into some diamond wins.
