Gem Crush Online Slot Review

The Gem Crush slot is a desktop and mobile compatible game from NetEnt that sees valuable jewels across a 6x8 grid, and where you win prizes with enough matched symbols clustered together. 

Pink, blue, and orange gems are among the colourful symbols, and you can also land Rainbow versions that upgrade others for potentially higher wins. Winning symbols get crushed via Avalanches that can lead to several prizes in a row. 

Random multipliers can increase any win value by up to 5x, and wilds help to complete clusters by standing in for other symbols. Play the Gem Crush slot machine and you can grab the greatest rewards from a free spins round with multipliers, giant wilds, and persistent upgrades.

This is a medium to high volatility game with a return to players of 96.13%. Play at our recommended Slot Sites and you can crush the casinos with wins of up to 4,361x your total bet.

How to Play the Gem Crush Slot

Gems come in two groups, with higher value versions encased by a layer of rock, and the less valuable ones already freed from their surround. Either way, they shine from the reels within a decorative stone alter in front of a waterfall in some mystical setting. It’s a fairly typical example of a gem-themed game and comes with a relaxing soundtrack of birdsong and cascading water.

You can play on iOS, Android, and Windows mobiles, or PCs at the top Betting Sites and other desktop devices for between 0.10 and 100.00. It’s easy to pick a suitable stake using plus or minus tabs to either side of the bet indicator below the reels. 

There are multiple features here, so it’s worth checking out the paytable to see the various ways to win prizes before you play with real money. It’s under the ‘?’ at the top of the game and reveals how much you win whenever matched symbols land in clusters of 5 or more. The highest paying orange gem pays 0.6x the stake for clusters of 5, increasing to 80x for clusters of 30 or more.

Non-UK players have extra options, such as a Buy Bonus feature, autoplay, and turbo modes.

Free Spins & Other Features of the Gem Crush Slot Machine

Every win triggers an Avalanche, with the winning symbols crushed as the others drop down to fill the gaps. You’ll see new symbols drop in from above the grid and if this new arrangement creates more clusters, the process repeats with no limit to how many can occur one after another. 

The golden W is wild and can substitute for other symbols to complete, improve, or connect clusters. A multicoloured Rainbow gem selects a random symbol type and upgrades it to a higher paying one for the spin. This makes it easier to form clusters if it transforms into a symbol type already on the reels. 

Random multipliers can apply to any win, with the prize boosted by 2x, 3x, 4x, or 5x. 

Square gem bonus symbols in at least 3 places award 10 free spins of the Gem Crush online slot reels. Special modifiers are active throughout –

Giant Wilds – A 2x2 wild symbol is guaranteed to land in every free game.

Increasing Multiplier – The win multiplier increases by 1x on every second free spin, to at least 5x at the end of the round.

Symbol Transformations – Any symbol upgraded by the Rainbow gem remains upgraded for the rest of the feature.

X-Strike – Randomly increases the win multiplier by 1x on any spin. 

Scatters don’t appear during this bonus round, so once the 10 spins come to an end, the free spins finish and you return to the base games.

Our Gem Crush Slot Rating

There’s nothing new about the graphics, although we’re not sure if this rock alter and waterfall are Norse, Aztec certainly, or just magic. However, it doesn’t stop the Gem Crush slot from looking good, and we’ve no issues with the gameplay and features.

You can get a big win from Avalanches, symbol upgrades, and random multipliers at any time. Free spins with an increasing multiplier, 2x2 wilds, and persistent upgrades can also form high-paying combinations, although it’s a pity that the bonus feature can’t retrigger. 

The return to players of 96.13% is good value for a medium to high volatility game, so if you enjoy the gem theme, and games with lots of fast-paced features, then Gem Crush is definitely a good choice at the best Online Casino UK sites.
