Lock Challenge is a web app that transforms any content into an interactive reveal. Create digital locks, share a link, and let the recipient crack the code to discover the hidden content.
What is Lock Challenge?
Lock Challenge hides content (text, links, images, HTML, PDF) behind interactive virtual locks. Creators choose from 15 playable lock formats, set the secret code, and share a link or QR code. Participants open the link on their phone and must solve the puzzle to access the content. No technical skills required, creating a lock takes less than two minutes.
Designed to look the part
A lock should look like it belongs to its occasion, not like a form. Each lock can wear one of 51 designed themes, one of 55 filmed objects that open on video, with sound, when it gives way (a chest, a safe, a vault door, a gift box) or your own two pictures, 37 typefaces, 36 celebrations with sound and your logo, with no Lock Challenge branding. The reveal can be a designed HTML page, and everything can be tried on a live preview before paying.
