How do I report a problem?

For a wrong card, tap "Challenge this answer". For a study game, use its flag button. For anything else that is broken, email [email protected] with the page, your device and browser, and what happened.

Pick the fastest way for your problem:

  • A SESK card looks wrong: answer it, then tap ⚑ Challenge this answer.
  • A study game card is wrong or not OK: tap ⚑ Flag this card. For the whole study game, use Flag this study game on its page.
  • Something on the site is broken: email [email protected].

When you email, tell us:

  1. Which page (for example /play/ or /make/).
  2. Your device and browser (for example "iPhone, Safari" or "Android, Chrome").
  3. What you did and what happened, plus any message you saw. A screenshot helps.

Before you write, a few quick fixes:

  • Reload the page.
  • Check you are online (some features, like the Daily Sprint, need a connection).
  • Sign-in trouble? See "I didn't get my sign-in code".

Please leave out personal details we don't need, and never send a PIN or sign-in code.
