## About

Lock Challenge lets anyone build a virtual lock: a puzzle players solve on their phone to open a hidden reward (a message, photo, video, link or the next clue). Pick from 14 lock types (number code, word, directional, colour, Sudoku, Wordle-style, musical and more), chain locks into a full escape game, add hints, timers and a leaderboard, and share by link or QR code. Teachers use it for classroom breakouts, escape-room owners put QR locks on props, and people use it for birthday surprises, proposals and team building. Players need no account. The free plan never expires.
