The Secret Global Scavenger Hunt

Letterboxing is a real-world puzzle game where people hide handcrafted stamps in public locations. Instead of digital points, players track their progress by trading unique ink imprints in private logbooks.

This hobby essentially turns the outdoors into a giant, analog treasure hunt. Participants create custom rubber stamps to mark their arrival at hidden boxes tucked away in parks or trails. It acts as a permanent, physical guestbook that chronicles the travels of strangers who share the same path. By leaving your own stamp behind, you become a permanent part of the local history for every future visitor.
