Try to build groups of matching jewels and win cash prizes in Gem Crush, a cluster pays slot released by NetEnt in December 2023. In our Gem Crush review, you’ll find out all you need to know before you play this jewels-themed slot for the first time. Gem Crush is played on a 6x8 grid and has medium-high volatility, with payouts of up to 4,361x your bet available.
Gem Crush is a cluster-paying slot with 6 reels and 8 rows. You can wager between £0.10 and £20.00 per spin.
As it uses the cluster pays mechanic, the slot game awards prizes for five or more matching symbols next to each other horizontally or vertically. It also features an avalanche mechanic: winning symbols disappear from the reels and new ones drop in to take their place. That means you can win more than once on a spin if winning symbols keep falling in the right spots.
Gem Crush has medium-high volatility and a Return to Player of 96.10%, which is only just above the average for a slot (96%). The maximum win on offer is 4,361x your bet, which is pretty decent, though high rollers searching for potentially massive payouts may want to look elsewhere.

While it doesn’t have the most eye-catching presentation, Gem Crush is still a good-looking slot with fluid animations and plenty of colour on the reels. The tranquil setting is a waterfall surrounded by tall pine trees, with flowing water and floating leaves adding realistic texture to the environment. The music is laid-back and calm, perfect for the serene setting.
There are eight paying symbols in Gem Crush, consisting of gems of different colours and shapes. You’ll see blue, purple, green, and yellow gems, which award lower payouts. The higher-paying symbols are similar but framed by brown rock.
Payouts vary depending on the symbols matched and the size of the clusters you create. For example, if you land a cluster featuring 30 or more symbols, you could win between 10x and 80x your bet.
Wild symbols substitute for standard symbols during the base game and Free Spins feature. Scatter symbols can trigger the Free Spins feature.

Rainbow Gem
The special Rainbow Gem symbols can appear anywhere on the reels at random. This symbol marks one type of symbol and levels it up to a higher-value symbol for the duration of that cascading spin.
Gem Crush is compatible with mobile devices as well as computers, so you can play on your smartphone or tablet with the same high-quality performance. The presentation is the same on mobile devices, and the simple controls are convenient for playing on a small screen. Gem Crush was made with HTML5, and will respond to the device you use for the best experience.
Book of Faith features a good range of bonus features that can boost the value of your payouts in different ways. Random multipliers, Rainbow Gems, and a Free Spins round are all available. Let’s find out how they work.
Multipliers can trigger at random on any spin, and the current multiplier is shown next to the grid for your convenience. The multipliers available are x2, x3, x4, and x5. These apply to all wins while active, so it’s possible to claim bigger payouts with their help.
The symbol for this is a pot filled with gold. The bonus trigger looks like Road to Riches, but the bonus screen contains bronze, silver, and gold pots. However, four symbols will only show silver and gold pots. Players will receive a multiplier, depending on which pot it stops. The gold pot will give a 500x multiplier.
If the Rainbow Gem lands on the reels, it chooses one symbol type to upgrade to a different type, though it lasts for the current spin only. That can lead to higher-value clusters, especially if a symbol upgrades to the Orange Framed Gem.
If you match three or more Scatters anywhere on the grid, you’ll trigger the Free Spins feature and win 10 free spins. On top of that, there are four modifiers to look out for:
You can’t retrigger the Free Spins feature, though. When it ends, you’ll go back to the base game.
Gem Crush is a decent slot with a nice design, good features, and a relaxing atmosphere that suits the countryside setting. The medium-high volatility means that most payouts are likely to be on the small side, though the maximum win up for grabs is still pretty good at 4,361x your bet. If you’re looking for a slot with massive prizes, Gem Crush isn’t for you.
The cluster pays and avalanche mechanics work well together, creating the potential for consecutive wins on a single spin. The random multipliers can take your payouts higher, too, as can the modifiers in the Free Spins feature. Its 96.10% RTP is slightly above average, too.
Overall, Gem Crush is a well-made slot that’s pleasant to play and includes some good features.
