What it is
Lock Challenge: the homepage
Lock Challenge is a browser-based tool for creating interactive virtual locks that hide content behind customizable puzzles. Creators choose from 15 lock formats including numeric codes, written answers, touch patterns, and musical sequences, set the secret answer, and share a link or QR code. Players open the link on any device and solve the puzzle to access the hidden content without needing an account or app.
The platform offers extensive customization options: 51 themes, 54 filmed opening animations, 37 typefaces, 36 celebration effects, and the ability to use custom images and logos. Hidden content can be text, images, videos, links, downloads, HTML pages, or PDFs. Designed for escape rooms, treasure hunts, education, team building, and events, Lock Challenge also includes Team Battle mode for competitive gameplay with live rankings and team coordination.
Building and previewing is free; publishing requires choosing a subscription length (one week, one month, or one year). Published locks remain online indefinitely. Players never pay and the service requires no technical skills.

Quick answers
What is a virtual lock?
A virtual lock is an interactive web challenge that protects hidden content. The creator chooses a lock, defines the correct answer and adds content to reveal. Players open a link or QR code, solve the challenge and unlock the content in their browser.
Do players need an account or app?
No. Players open the shared link on a phone, tablet or computer and solve the lock directly in their browser. Only the creator needs an account, and only to save and publish.
What can be hidden behind a lock?
Anything: text with bold, italics, sizes, links and lists, the next clue in a chain, a link or a download, an action button, an image, audio, a YouTube video, sanitised HTML and several items in one reveal.
Do players pay?
No. Players never pay and never need an account: they open the link or scan the QR code, and play.
Do players need an account or an app?
No. Players open the shared link on a phone, tablet or computer and solve the lock directly in their browser. Only the creator needs an account, and only to save and publish.
