Put a daily mystery on your site

A free, self-contained widget that shows today’s five-minute detective puzzle and refreshes every morning. No script, no account, no tracking pixels — one line of HTML. Great for a blog sidebar, a puzzle roundup, or a newsletter.

How it works

The widget is a plain <iframe> — it loads in its own sandbox and can’t touch your page.
It always shows the live puzzle for the format you pick, updated daily. You paste once and never touch it again.
Readers who tap Play free open the full puzzle on Daily Casefile in the same tab. Everything is free and no sign-up is required.
