Crystal Cavern slot review

Last Update: 22.05.2020. Author: SlotCatalog.

Crystal Cavern is set in an underground cave with glimmering crystals and luminescent mushrooms, and Kalamba Games has made a visually pleasing game here for sure. The gameplay is somewhat unusual, since you have to commit to cycles of 10 spins, but it all makes sense once you get into it.

It all plays out on 6 reels, 4 rows and 4,096 ways to win, and the maximum and minimum bet level depends on which Hyper Bet multiplier level you choose. There are 3 Hyper Bet levels (1x, 2x and 3x), and you can place bets between 30p and £60 per spin from this option. Once you have committed to a bet level, you will need to stick to that for the next 10 spins.

The game’s RTP will also vary according to the Hyper Bet level you choose, and the multiplier you get will only benefit you if you actually manage to trigger the bonus round within the 10 spin cycle. Everything resets after 10 spins, which can be somewhat frustrating in the longer run. If you have the patience for a volatile game, Crystal Cavern offers massive theoretical max wins.

What symbols are there?

All the higher value symbols are different colored crystals here, with the red crystal being the most paying symbol of them all. The low value symbols are not your usual royals, but instead a bunch of more or less glowing mushrooms of various kinds. You need between 3 and 5 matching symbols on a payline to win, and here is the paytable for Crystal Cavern slot:

  • Red crystal - Pays 5x for 5 on a payline
  • Yellow crystal - Pays 4.1x for 5 on a payline
  • Green crystal - Pays 4.1x for 5 on a payline
  • Blue crystal - Pays 3.3x for 5 on a payline
  • Purple crystal - Pays 3.3x for 5 on a payline
  • Div mushrooms - Pay between 2x and 1.6x for 5 on a payline

What are the bonus features?

The base game comes with a wild symbol, which is a stone block with the word “wild” written on it. Hard to mistake, in other words, and we also like the fact that all higher value symbols come with frames. This way it’s easy to distinguish them from the lower value mushroom symbols.

On the left-hand side of the reels you’ll see a Hyper Bet meter, and here you can choose between 3 different bet levels. Each bet level corresponds to a different multiplier in the free spins feature, but increasing the bet level will naturally also increase your bet. The multiplier goes from 1x to 2x and 3x, and you have to pay twice as much per spin if you want the 3x multiplier.

The game’s RTP is also affected by your chosen Hyper Bet level, and at level 1 your RTP is 95.85 %. If you chose to go with bet level 2, your RTP will increase to a very decent 97.10 % and level 3 will give you an RTP of 97.72 %. Remember, the multiplier you get from the Hyper Bet only applies in the free spins feature, which we will discuss next.

Free spins in Crystal Cavern

While spinning in the base game, you’ll notice pinkish orbs landing on the reels and being collected in the meter on the right-hand side. On top of that meter you’ll see a sign that says “3 free spins”, and this is the minimum amount of spins you get when you fill the meter with orbs.

The meter resets after every 10 base game spin, which means that you always have only 10 spins to fill the meter before you start all over again. You need to collect 6 orbs to get to the free spins feature here, and every orb above 6 that you collect, will add 1 extra spin to your total.

Each orb also has a unique coin value, and can sometimes be collected with a multiplier value as well. All the accumulated value and multiplier value will be carried over into the free spins bonus round, and you also get 1 extra free spin for every orb symbol that lands during the free spins feature.

All winnings are subject to your accumulated multiplier, plus any multiplier that you might land on that spin. At the end of the bonus round, all orb symbol values from the very beginning of the 10 spin cycle will be summarized. And this sum total will then be boosted by the total multiplier you have accumulated (capped at 5x, 9x and 13x for the 3 different Hyper Bet levels).

What is the jackpot (max win)?

You will not find any kind of jackpot on Crystal Cavern slot, but you can still land some solid payouts here. Filling the reels with nothing but the highest paying symbol, would give you the theoretical max win of 5 x 4,096, which equals 20,480 times your stake. Note that we’ve not even factored in the free spins multiplier here. The realistic max win is probably a lot less though, but big wins are certainly possible in this game.

SlotCatalog verdict

Crystal Cavern is not as complicated as it may sound when we write about it, but you will need to commit for 10 spins when it comes to bet level and Hyper Bet level. The volatility is on the higher side of medium here, and you can expect a “close, but no cigar” feeling in most of the 10 spin cycles. Winning big is possible for sure, but you need to carefully consider which Hyper Bet level you want to go for.


  • 10 spin value/multiplier collection
  • Free spins with multiplier wins
  • Choose between 3 Hyper Bet levels
  • Medium to high volatility
  • Theoretical max of of 20,480x + multiplier


  • No bonus game
  • Cannot change bet level before 10 spin cycle ends
