Playing Crystal Cavern is really simple. The Hyper Bet multiplier level you select will determine the maximum and minimum wager levels. The game has 6 reels, 4 rows, and 4,096 ways to win. Using this option, you can set bets between 0.30 and 60 per spin on one of the three Hyper Bet levels (1x, 2x, and 3x). You must maintain your bet level for the following 10 spins once you've decided on it.
Several coloured crystals serve as the higher value symbols in this game, with the red crystal serving as the highest paying one. The low value symbols are a variety of more or less bright mushrooms rather than the standard royals. The paytable for the Crystal Cavern slot machine is as follows:
In the fundamental game, as the reels are turning, you'll see pinkish orbs settling on them and gathering in the metre to the right. The number of free spins you receive when you fill the metre with orbs is shown by the sign that reads "3 free spins" on top of that metre.
The metre refreshes after every 10 base game spins, so you never get more than 10 spins to load the metre before it resets. In order to access the free spins feature, you must gather 6 orbs. For each orb you collect after that, you will receive 1 more spin.
Every orb has a different currency value, and some of them can be acquired with multipliers as well. The free spins bonus round will include all of the accrued value and multiplier value.
