Questions or something not working as expected? The notes below cover what people ask most. If they don't help, write to us and we'll reply by email.
Missed questions are saved to your Retry Box, newest first. Tap Replay there to try up to ten of them again; each one you now get right leaves the box. You can also empty it with Clear all.
Today's set follows your device's date, so a new one appears after midnight local time. If you change the date or time zone on your device, the set changes with it.
Not at the moment. Progress, stars, milestones and the Retry Box are saved only on the device you play on, and nothing is uploaded. Deleting the app, or using reset in Settings, clears them.
Include your device model and iOS version if you're reporting a problem.
