Common questions

How do I restore a purchase?
Settings → Purchases → Restore. Purchases are tied to your Apple Account, so they come back on any device signed in to it.

What does the free tier include?
Easy and Medium at every puzzle, three new puzzles and three hints a day, and the Daily Puzzle — which is always free.

How do I cancel a subscription?
Through your Apple Account settings, as with any App Store subscription. Monthly and yearly plans renew automatically unless cancelled at least 24 hours before the period ends.
