Discover every element that makes Crystal Caverns an exceptional slots experience.
The Wild symbol is depicted as a glowing crystal that substitutes for any regular symbol to complete a winning combination. When a Wild lands on the middle reel, it can expand to fill the entire reel (Expanding Wild), significantly boosting your chances of winning at 150r.
Land 3 or more Scatter symbols on any reel to trigger Free Spins mode. At 150r, these Scatters appear as glowing blue crystals. The more Scatters you land, the more free spins you receive — up to 20 at once!
In Free Spins mode, every time a Scatter reappears you receive additional free spins — and this can be retriggered indefinitely! 150r players have accumulated over 50 free spins in a single session thanks to this highly rewarding retrigger feature.
Forget the limitations of traditional paylines — Crystal Caverns at 150r uses a 243 ways to win system. Every time matching symbols land on adjacent reels from left to right, it counts as a win. This gives you far more winning opportunities every spin compared to classic slots.
During Free Spins, multipliers activate automatically. Every win is multiplied by 2x up to 10x depending on the number of Wilds in the combination. At 150r, this means big wins can reach up to 5,000x your bet!
Crystal Caverns at 150r is fully responsive — enjoy a comfortable experience on both smartphone and tablet screens. HTML5 technology ensures the stunning crystal animations run smoothly with no lag, even on a standard internet connection.
