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 organisations use it for team building and events. Players need no account. Free plan (3 locks, never expires); one-off Event Pass and Pro plans available.
