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.","categories":["saas","productivity","education"],"features":["14 lock types","Multi-step escape games","QR codes","Hints, timers and leaderboard","43 filmed unlock animations with sound","Templates","No player sign-up"],"pricing_model":"freemium","pricing_summary":"Free plan never expires","cta_label":"Build a lock free","screenshot_url":"https://screenshots.azn8.com/screenshots/a34f921a-7e70-4c37-b3fa-370b6435df32/3dc58a0f42ddfd7a.webp","screenshot_status":"ready","screenshot_updated_at":"2026-10-06T02:31:39.845Z","status":"live","source":"human","url":"https://azn8.com/listing/lock-challenge","created_at":"2026-10-06T02:31:26.816Z","updated_at":"2026-10-06T02:31:26.816Z","published_at":"2026-10-06T02:31:26.816Z","featured":false}}
