Sounds intriguing, but a rotating puzzle vault can’t rely on luck alone. First, make the magnetic lock a dual‑stage system: a primary magnetic seal and a secondary mechanical latch that only releases when the right sequence is entered. That way a thief can’t just spin the carousel and pull a coin out. Add a tamper‑sensing ring around the rim that triggers an alarm if someone tries to unscrew the base. Keep a tiny motion sensor inside each compartment to log every rotation—so you know if someone’s been messing with it. Finally, use a unique fingerprint or RFID tag for each tap sequence; that way the puzzle itself acts as a two‑factor authenticator. Fun to play with, but rock‑solid when you’re serious.
