Dig into the mine and unearth the birthstones.
Numbers = how many gems touch a tile. Finding a gem is free — only empty digs cost a dig.
Two ways to claim a gem: tap it for safe base points, or mark it (💎 Gem here) and hit 🔒 Lock in — correct guesses pay +50% bonus, wrong ones cost you, and a flawless sweep earns a perfect bonus + ⭐⭐⭐. Use ✖ No gem to rule tiles out.
Surprises hide in the dirt: ⛏️ pickaxe (+3 digs) and a 🗺️ treasure map (reveals a gem).
