Code Quest

Crack ten codes to find your way home: binary, hex, octal, letter codes and Morse, with hints when you’re stuck. Then turn your own house into a code hunt with printable clue cards.

🧭 The trail home

Paper and a pencil help. Your place on the trail is saved on this device.

🗺️ Make a code hunt at home

List your hiding places in order. Each clue card gives the next place in a code; the hunter decodes it, finds the next card there, and so on to the prize. Use short names a child can read once decoded, like mailbox or under the couch.
