Crystal Cavern Slot Review – Kalamba Games

It has been a month or two since we saw a Kalamba Games slot release. Their most recent was titled ‘Joker Max‘, which used the common Joker theme and paired it with exciting gameplay. My personal favourite game by the studio is ‘Pyro Pixie‘, due to the unique gameplay and potential on offer. However, next from Kalamba Games is ‘Crystal Cavern‘ available to play now across all sites.

The Crystal Cavern is filled with precious stones and a unique atmosphere. The slot background is filled with the cave terrain and multiple glowing gems to be seen. There are also small animations of sparkles. The visuals have impressive detail and they all tie in well together for the set theme. Premium symbols are different coloured gems, while low paying symbols are various plants such as mushrooms.

This game has a setup of 6 reels by 4 rows, this includes 4,094 pay ways. Crystal Cavern is a medium variance game due to the set RTP of 97.62% and rating of 8/10 based on volatility by the studio. You can bet from £0.60 – £300.

Crystal Cavern Paytable & Symbols

Crystal Cavern has 13 symbols in total, this includes 6 low paying symbols. These are represented by pink, purple, blue, green, orange and red mushrooms/plants. There are also 5 premium symbols, these are represented by purple, blue, green, orange and red gems. In addition to these paying symbols is a wild symbol and orb symbol. The highest paying is the red gem, this symbol pays 6x for 6 across a pay line. The wild symbol substitutes for all symbols except orb symbols.

Crystal Cavern features

When you set your initial stake, this stake is stuck for 10 base game spins. During these spins, cash orb symbols with coin values and multipliers are collected. If 6 or more orbs are collected the ‘Free Spins’ feature is activated. Bet and Hyper bets can only be changed at the beginning of the 10 spin cycles.

Hyperbet selection determines the multiplier value for each cash orb and multipliers. The higher the Hyperbet, the higher the game’s volatility will be. The RTP will also increase overall.

During the ‘Free Spins‘ feature, 1 extra spin is awarded for each orb symbol that lands. Collected multipliers are applied to all subsequent wins. At the end of this feature, the multiplier is applied to the total win from cash orbs. The multiplier value is based on the Hyper Bet level.


Overall, I think this game does show new unique qualities. However, the base game playing in rounds of 10 spins is something not every player will enjoy. Due to the stake lock, the orb symbols are the only way this game will pay out well. Be sure to try the game for yourself and check out our exclusive casino offers.
