KEYSMITH: Crack the Lock

Every lock hides a row of pins. Every lock has exactly one answer. And you can find it with logic alone — no guessing, no luck.

KEYSMITH is a cozy 3D logic puzzle about real lock mechanics. Read the evidence a burglar left behind, cross out what's impossible in your locksmith's notebook, and cut the one key that must be right. Then slide it in and hear the CLICK.

🔑 HOW IT WORKSThe lock never tells you which pin is right — only how many are ✓ set, ▲ cut too high or ▼ cut too low. Combine the rows, think it through, and the answer falls into place. Every single lock is generated and then proven by a solver to have exactly one solution you can reach by reasoning.

🧩 THREE KINDS OF LOCKS• Case Files — classic deduction puzzles, like Sudoku for locksmiths.• Tricky Locks — cursed locks that haven't picked their secret yet and dodge every guess. Luck can't help you: design smart probe keys and beat the par.• Heists — partial evidence plus a stethoscope. Decide what to deduce and which question to ask.
