Crystal Cavern from Kalamba Games takes you deep into an underground cave where you will search for precious gems. The  video slot offers you bonus spins, multipliers and a Hyperbet feature with 3 levels.

About the slot

Crystal Cavern is a 6 reel slot with 4,096 ways to win, it is playable across all devices from 60p up to £300 per spin. It is worth noting that when you select your bet  the amount you wager will be valid for 10 spins and cannot be changed until they have finished.The transparent reels are set deep inside a cave with lots of shimmering gems around. Lower value symbols are pink, blue, orange, purple, green and red mushrooms, followed by purple, blue, green, orange and red crystals, the red crystal has the highest value, landing 6 on a payline will pay out x6 of your wager.The wild symbol is the blue square stone and can replace all other symbols bar the orb.

Gameplay

To the left of the reels you will see the Hyperbet meter, you can opt for level 1, 2 or 3, this will cost you more, but you will get higher value multiplier in the free spins.Any pink orbs appearing on the reels will be collected in the meter on the right hand side of the reels, you need the minimum of 6 orbs to trigger the free spins. Any further orb that lands on the reels will give you another bonus spin.Each of the orbs wills show a cash value and a multiplier value. Bet level one will award you with a multiplier up to x5, level 2 – up to x9 and level 3 – up to x13.Crystal Cavern has stunning visuals and a fab soundtrack, and really enjoyable to play, although I didn’t like the idea of only being able to change your wager after every 10 spins. It has a med-high variance slot and has an RTP of 97.73%. You can pocket up to x20,480 of your wager.
