Common questions

When does the daily puzzle reset?

The website and iPhone app refresh at midnight London time, so both versions show the same daily puzzle. If you leave either open, it should refresh automatically when the new day starts.

Can I play offline?

Yes. Thread is built to be local-first. The main gameplay does not depend on a network connection.

How do reminders work?

If you turn them on, Thread can send local reminders at 9:00 AM and 9:00 PM. You can change this in the app’s Settings.

How do I reset my progress?

The public app does not currently include a reset control. Removing the app clears device-local progress, but progress stored in your private iCloud account may return after reinstalling. Email support if something looks wrong.

How do I report a puzzle issue?

Email support with the puzzle number or date, what answer you expected, and why you think the clue set was unclear or incorrect.
