Crystal Cavern is an online slot that has gone relatively unnoticed since its release in February 2020. And I’d like to remedy that because it has a lot to offer for a type of player who often goes overlooked in a world where reviews tend to focus on intense and ground-breaking mechanics and high-paced slots.

Crystal Cavern game overview
This game has a reasonably wide range of return to player (RTP) from 95.85% to 97.72%. This is partly because the Hyper Bet system lets you choose different wager levels for a fixed set of 10 spins. The same goes for the volatility, which can go from medium to high, with relatively frequent hits, with a maximum win of 20,480x your wager.
Crystal Cavern is a collaboration between Kalamba and Relax Gaming.
Crystal Cavern has a rich design that takes you deep into the earth to hunt for precious crystals. But don’t let the title fool you: there’s much more than crystals hiding in the deep. Elegant mushrooms, glowing plant-life and shiny orbs.
I especially like how the visuals are paired with low-key, mysterious —almost mystical— music. This blends in with the gentle and fine-tuned sound effects that heighten the sense of depth and peace.

Crystal Cavern Gameplay
The Crystal Cavern slot begins the game by choosing a fixed bet level for the ten base spins. You can then select one of three Hyper Bet levels to change the value of multipliers, increasing the volatility.
As you play, you can collect Cash orb symbols that give you great multipliers. Collecting six Cash orbs will trigger free spins at the end of the round. Wild symbols substitute all symbols except for cash orbs.
Multipliers are cumulative, so they apply to subsequent wins. This can make all the difference during free spins.
During free spins, each Cash orb symbol that appears wins you an extra free spin.

Crystal Cavern Slot Review: Relax in the deep
Suppose you’re looking for a slot machine that combines simple gameplay with sophisticated design. In that case, Crystal Cavern is definitely a must-try.
This game has several ways to win beyond pay lines, with different winning combinations of matching symbols. There are also attractive free spins multipliers that can yield some pretty exciting wins, despite this mobile slot game’s moderate volatility.
That said, it’s possible to change the bet level and thus aim for bigger wins. But while the symbol-match ways to win system will land frequent hits, they won’t be enormous. On the plus side, you can bet low and play for much longer with a modest bankroll. The fact that the game has you play with a fixed bet system for sets of 10 spins is also a good feature for players looking for an excellent environment to exercise responsible gaming.
Again, this slot is for those who want to get away to a rich and beautiful underground world, to enjoy a quiet place where they can relax playing a smooth game.
