Common questions

The Daily Challenge won't load. It needs an internet connection the first time each day's puzzle is downloaded. After that it is saved on your device and works offline. Regular games never need a connection.

Do I need an account? No. Nothing is collected. See the privacy policy.

Why did my streak reset? A streak counts consecutive days on which you finished the Daily Challenge on its own calendar day. Completing a missed day later counts as a completion but cannot repair a broken streak.

Can I move my progress to a new phone? Progress is stored only on the device, so it does not currently transfer between devices.
