What is this mobile slot about?

Enter this Crystal Cavern slot game, and you’ll find yourself in a strange outlandish world full of fantastical gems, strange fauna, and very expensive magical orbs.

This Kalamba machine looks pretty good. The sister game, the Zombie Queen slot has an interesting well-done theme, and whilst this Crystal Cavern video slot isn’t quite as interesting, it’s fun enough.

You are on an alien on a Fantasy world full of dark purple hues and pretty mushrooms and fluorescent plants as the low paying symbols, and the Crystals as the high paying ones.

And this has ALOT of symbols, mostly because you get 6 reels and 4 rows with 4096 ways to win, so plenty of space to cram as many symbols as you can. Which is a shame, as the base game pays almost nothing because of it.

You can’t change your bet for 10 spins

This annoyed the F*** out of us. You have to choose which bet level you want to choose, and it’s not really a choice, as you have to go with Hyperbet level 3.

That means the minimum bet of the Crystal Cavern slot is 1.20 a spin. Why do you have to bet so much? Because the RTP increases from an ok 95.85% to a huge 97.72%. Which is a massive improvement, and even better than the Starburst slot game.

You also increase your chances of getting bigger multipliers in the free spins bonus round, up to 13x rather than up to 5x. So you see, the extra bet is a must for a game with a fairly below average paytable value.

Which comes with its own problems as for 10 spins you are locked into a bet amount, as that’s how you trigger those magical Crystal Cavern slot.

ALL the wins are in the free spins

How do you trigger the free spins? By collecting orbs during those 10 spins. That’s it. That’s the whole point of locking you into those 10 spins, is so you can collect orbs and trigger the Crystal Cavern bonus games.

Almost every single fruit machine with free spins manages to give us bonus spins without forcing us to stick to one bet. So if you do use autoplay, keep a close eye on your budget as if you do want to change your bet.

Getting those orbs is no easy feat, but they can come with multipliers – which helps boost those wins.

So it’s not that the Crystal Cavern game doesn’t have some good aspects. It’s just that with so much choice out there, why would you choose to confine yourself to a game that limits all your options only to give you free spins?

Play on the Solar Queen slot, which also has a 10 spin cycle, that just works in your favour, rather than in the favour of the video slot.

In-game bonus features

The Hyperbet Bonus: This increases your bet, the overall RTP of the game and the multiplier value for the free spin round:

  • Hyperbet level 1: 95.85% RTP / Top Multiplier x5
  • Hyperbet level 2: 97.10% RTP / Top Multiplier x9
  • Hyperbet level 3: 97.72% RTP / Top Multiplier x13

Cash Orb Feature: You have to pick your bet for every 10 spin cycles, and you can't change your bet in those 10 spins. At the end of this cycle, the number of cash orb symbols is counted and evaluated. If 6 or more cash orb symbols have been collected during those 10 base game spins, trigger the free spins.

Each cash orb symbol has a value and may have a multiplier associated with it. These are carried into the free spins if they are triggered.

Free Spins Bonus: During the free spin bonus, triggered via the cash orb feature, every cash orb symbol that appears give you an extra 1 free spins. You start with 3 free spins. You start the free spin with the value of the multiplier gained from the Cash Orbs.

How big a multiplier you get will depend on the Hyperbet level you've chosen.

  • Bet Level 1: The multiplier increase by x1 for each cash orb with a multiplier
  • Bel Level 2: The multiplier increase by x2 for each cash orb with a multiplier
  • Bet Level 3: The multiplier increase by x3 for each cash orb with a multiplier

Closing thoughts

Crystal Cavern is a 6 reel with 4-rows video slot with 4096 ways to win, with a free spin bonus and 3 different base bets.

We don't know what went wrong with this game but forcing us to bet 10 spins on the same bet just so we can maybe catch some free spins... annoyed us. This is no doubt not helped by the fact that you need to bet a minimum of 1.20 a spin in order to get any decent wins.

If you can increase your bet to hyperbet level 3, you could even add a star to this Crystal Cavern slot review, because it has fun moments and big enough multiplier to maybe give you hope for more.

But personally, we're not sure we'll be coming back, meaning this gets a "It's playable, but not fun enough" 2 stars. Go and play on Rio Stars slot by Red Tiger Gaming if you want something a little bit different.
