Crystals Digger RTP and Volatility

The slot features medium-high volatility and 90.39% RTP.
We have no doubt that being a miner is hard, but in this slot, you will have to go through an ordeal to get some gems as it comes with a medium to high volatility. This means that you will need the patience to wait for the winning combination, but each successful spin will bring you a big payout. The RTP is not on your side as it is only 90.39% which is far, far below the industry average.


Crystals Digger

The game tells the story of people who set themselves the task of exploring everything that is hidden underground. Be it formations from natural phenomena such as dungeons, or gems that hide underground. Therefore, if you like to explore and discover new places and objects, you will love the design of this slot.

All actions take place against the backdrop of a dark cave full of huge purple gems. In the right near the wooden playing field is a tired-looking old digger who holds 2 picks in his hands. The design is top notch and we like that there are a lot of animated elements in the game.

Gemstones of different colors appear on the reels as premium symbols and playing card suits as low paying symbols. There are also Bonus Boxes (Scatters) that you need to activate the free spins feature.

Wheel of Fortune

You need to press the start button if you want to spin the small wheel and if it hits the arrow, the big wheel will start spinning. If the big wheel has a jackpot section, you will win the cash jackpot, and if not, you will win jackpot points to increase the jackpot coefficient for the next half hour of play.

Free Spins

The slot activates the free spins feature as soon as 4 or more Scatter symbols appear on the reels at the same time. You will get 10 free spins during which Scatters can land to award you at least 5 extra free spins. The maximum number of free spins is 300.

Free spins are supplemented with a win multiplier. Thus, after each bonus round, your win will be multiplied by the sum of the multipliers that have hit the playing field. The multipliers look like red bombs and they can be 2x-100x.

Craft Bonus

Crystal Digger offers you the option to buy a bonus and if you want to get a higher probability of getting big wins then you’ll need to increase the price of your purchase. Unfortunately, you will not encounter this feature in the demo mode.

Crystals Digger Demo Play

Want to have fun for free? No problem! This slot machine comes with a demo version. To get access to it, you do not even need to create an account on the casino website. Just click "Play Demo" and the slot will start. In this mode, you will be able to bet with "fun" coins, which are used instead of real money to spin the reels, create prize combinations, activate bonus features, and receive prizes. Of course, you will not be able to withdraw the prizes that you won in the free mode.

Max Win

Win up to 2,000x the bet.

The most you can hope for by spinning the reels of this slot is for a prize that will increase your bet by 2,000x. Is it a big maximum prize? We don't think so, it will be big only for those players who are used to playing with big bets.


To access the jackpot feature, you must first accumulate jackpot points. These points are automatically awarded to you whenever you place a bet in the base game. Therefore, you should keep a close eye on the indicator, and once it is full, you will see 2 wheels. By spinning each of them, you can win prizes!

Overall Rating

The game certainly looks nice and modern, but it's a pity that we didn't see anything new in the mining theme here. Everything according to the standard recipe: a dark mine, gems, and a white-bearded old miner. As for the gameplay, it is fast even without the autospin mode enabled, but the base game is almost empty, so all you will do is wait for the Free Spins feature with multipliers to activate or wait for the counter to accumulate enough JP points to activate the Wheel of Fortune with jackpots. All in all, this is a standard good game for high-risk players/high rollers, but it confuses us a lot with its low RTP.

Can I buy the bonus round in Crystals Digger?

This slot includes the Craft Bonus feature so you can buy the bonus round at any time and choose from different bonus drop options. The value of the bonus will depend on the bet made in the base game.

What about free mode?

The provider took care of the availability of a free demo mode for their new machine. It's available right on this page! With it, you will be able to bet with "fun" coins instead of real money and get everything you get in the full version, except for real wins of course.

What is the Return to Player (RTP) in Crystals Digger?

The RTP of this slot is only 90.39% which is far, far below the industry average.
