Play Vault Cracker — Code Breaking Puzzle

Hints cost 10 coins

Vault Cracker is a code breaking puzzle where you deduce rather than guess. Each safe shows earlier attempts with feedback: a green dot for a right symbol in the right slot, a gold ring for a right symbol in the wrong slot. Exactly one code fits them all. Cross symbols out on the notepad, then open the vault within three tries. On the hardest vaults, one attempt lies.
