Gem Burrow: Drop Merge Puzzle

Moki the mole found a crystal cave under his garden! Drag to aim, let go to drop a gem into the mine cart — two of the same gem that touch merge into a bigger, shinier one. Pebble, garnet, citrine, topaz… all the way up to the heart crystal. Just don't let the pile cross the top line! 💎 DROP & MERGE One finger is all you need. Gems roll, bump and stack with real physics, so every drop counts. Chain merges for big score bursts and watch the gems grow. ⛏ 60 DEPTHS TO DIG Each depth asks for something new: make a target gem or reach a score before you run out of gems. Rocks show up deeper down — they don't merge, so crack them with a merge right next to them. Clear depths to earn up to 3 stars. 🌙 TODAY'S VEIN A fresh seam every day with 50 gems, the same for everyone on that date.
