Common questions

My progress disappeared

Progress on the website is stored in your browser. Clearing site data, using private browsing or switching browsers will reset it. In the app, progress lives on the device.

I bought hints and did not receive them

Open the app's shop and tap Restore purchases. If the purchase still does not appear, email us with the App Store receipt and we will sort it out.

I think a puzzle is unsolvable

Every puzzle is machine-verified to have exactly one solution reachable by logic, but if one looks wrong to you we want to know. Send the puzzle number and we will re-check it by hand.

How do I cancel or refund a purchase?

Purchases are handled by Apple. Use Apple's report a problem page or Settings → your name → Subscriptions on your device.
