Crystal Grotto
Crystal Grotto is a calming idle tap game. Tap anywhere on the cave wall to drip mineral light onto the rock, and glowing crystals sprout and keep growing over time — even while you are away. Each crystal has its own color, facets, and glow, and your grotto develops a unique look the longer you tend it. Track how many crystals you have grown and how old your cave is, capture a snapshot, and share a beautiful crystal card with friends. Your progress is saved locally so your cave is always there when you return. Available in English and Simplified Chinese.
