For writers and teachers
Put a daily puzzle on your site
Run a blog, a newsletter, a library or a class page? Add the Crux daily puzzle card. It links your readers to the free puzzles that play in any browser (Words of Hanoi, Atlas Streak, The Polyglot and Insane Pour), with no ads. The card itself sets no cookies, runs no script and never changes size.
The code
Paste this where you want the card to appear:
<iframe src="https://crux.quest/embed/daily" title="Daily puzzles from Crux" width="340" height="320" style="border:0;max-width:100%" loading="lazy"></iframe>
You can also link to a single game: crux.quest/hanoi for a daily word sort, crux.quest/atlas for a map game, crux.quest/polyglot for a language quiz. Each is free to play with no sign-up.
For a newsletter
Email clients do not run frames, so link the card instead: "Today's free puzzle: https://crux.quest/hanoi". The page shows a share card in most email and chat apps.
The rules
- Free for any site, commercial or not. No sign-up and no attribution needed beyond the card itself.
- The card loads only from crux.quest and sets no cookies.
- Crux is rated 13+ on the App Store; the browser games have no chat and no purchases.
