How to crack a vault
Use two clues
Exact means the digit and position match. Misplaced means the digit is in the code but belongs in another slot. A digit is counted only once.

Early vaults have four digits. Later vaults have five, then six. You have a limited number of guesses and can retry any unlocked vault. Progress and fewest guesses stay on this device.
