Carnelians are orange, sapphires are blue, emeralds are green and citrines are yellow. In Gem Crush by NetEnt, all of these gems pass by. Your goal? Collect as many of them as possible.

Gem Crush - Slot Review

A magical oasis of tranquility

You are almost going to question the rarity of the gems mentioned above while playing Gem Crush. Indeed, the 4 gems mentioned above can be found in abundance in this slot machine.

Gem Crush takes place near a waterfall and right in front of an indefinable shrine. The shrine is composed of boulders of various sizes, each of which is also carefully engraved with a scroll pattern. It has something soothing and magical at the same time.

The same can be said about the soundtrack. Or, well “soundtrack”: actually, Gem Crush has no soundtrack at all. There are bird sounds in the background and you can hear the water falling from the waterfall. Only when you actually spin the reels does music sound.

As a player, you are then graced with the soothing sounds of a harp.

How does Gem Crush work?

You create winning combinations in Gem Crush by spinning a cluster of 5 identical symbols on the playing field.

The winning symbols are then removed from the gaming area to be replaced by new symbols that fall from the top down.

Want to play in a casino with real money? You can do so from a minimum of $0.10 and a maximum of $20 per spin at online casinos. The RTP is set at 96.10% and there is medium to high volatility. It is also important to mention that in Gem Crush you can win up to 4,361 times your bet.


By far the most obvious feature of Gem Crush is the free spins feature. Therefore, the slot does not have much more to offer, although the multiplier and rainbow gems are always lurking.

PROs & CONs of Gem Crush


  • 4 special modifiers can come into play during the free spins feature
  • Uses the cluster pays mechanism and the waterfall mechanism
  • A multiplier can be activated at any time


  • Basic statistics


At any time while playing Gem Crush, a multiplier can be activated on winning combinations. This is a multiplier of x2, x3, x4 or x5.

Rainbow gem

When a rainbow gemstone appears on the playfield, a random symbol is chosen as the upgrade symbol. All units of the upgrade symbol are upgraded to units of another symbol type. At most, this can occur 4 times per spin.

Gem Crush free spins

You can earn 10 free spins in Gem Crush by spinning 3 scatters on the playfield. During these free spins, there is a continuous chance that 1 or more of the following 4 special modifiers are activated:

  • Increasing multiplier triggers a multiplier that increases by +1 every second spin. This multiplier is applied to all winning combinations and is therefore not reset between spins
  • XStrike can increase this multiplier even more. It does so by +1 each time this modifier is activated
  • Symbol transformation can occur up to 4 times. It causes units of low-value gem symbols to be upgraded to their framed high-value variant
  • Colossal wild places a 2×2 wild symbol on the playfield every free spin

What do we think?

Gem Crush remains too superficial for our taste, which is why we didn’t always enjoy ourselves while playing.

Yes, the theme is fun with its soothing yet magical twist. The audiovisual part will get you all zen, but in our opinion, so will the features. And that, of course, is not a good sign, because that means those features provide too little excitement!

In addition, the statistics of Gem Crush are not hot either. We would rather play 1 of the other online slots that the world wide web has to offer us.


Yes, there are bonuses. Players can count on free spins, a risk round for doubling, a themed bonus round.

Gem Crush is an enchanting online slot that stands out for its mystical theme, featuring magical symbols and an intriguing storyline about ancient spells and hidden treasures.

To play Gem Crush, you need to select your bet size, spin the reels, and match  symbols to win. The game offers easy-to-understand controls and user-friendly gameplay.

The game offers a top prize of 4,361x, making it an attractive choice for players looking for big wins in the world of magic and mystery.
