About
Every object hides a gem. Get it out.
Tap to swing the hammer and watch chunks fly. Swipe to cut a real slice through anything. Hold to drill in, carefully. The moment you can see the gem, it pops free.
26 OBJECTS, ONE GEM EACH
Brick, soap, geode, cake, watermelon, piggy bank, marble column, iron meteorite and more. Each one breaks its own way.
THEN THE GAME CHANGES
Just when you've got the hang of it, a twist: slam the object down onto a hammer, carve it on a spinning lathe, turn it to fit through a hole in the wall, shake the gem loose, or flip a knife through obstacle courses in Knife Run.
THE OBJECT FIGHTS BACK
Cracks that run toward the gem. Steel plates hiding it. Ice that refreezes. Glass decoys that glow like the real thing. Hit too hard and the gem shatters.
COLLECT THEM ALL
36 gems, graded by how clean you dig them out. Earn shards, upgrade your tools, unlock new knives, beat each chapter's boss and hunt for the legendary Pink Diamond. When the chapters are done, endless Mysteries and a new Daily every day.
