Lock Challenge

About Lock Challenge

Lock Challenge is a browser tool for creating virtual locks that hide a message, photo or video behind a puzzle. It is aimed at teachers, escape room hosts, party planners and businesses that want a playful reveal. Creators build a lock in a couple of minutes, set a numeric code, written answer, pattern, colour sequence or other puzzle type, and share it by link or QR code.

Players open the lock on any phone or computer without installing an app or creating an account. Answers are checked on the server rather than sent with the page, and automatic hints can be added so nobody gets stuck. Customisation covers themes, fonts, celebration animations and sound.

The product also offers a Team Battle mode for classrooms and escape rooms, where teams race to open the same locks while a live ranking updates. Pricing is a one-time payment for a chosen period, and players never pay.
