Frequently Asked Questions

How do I play?

Tap an empty cell. Write a digit from 1 to 9 in the lower part of the bubble, or tap a number on the pad. The puzzle is solved when every cell is correct.

Handwriting is not working

The first time you write, the app may download an on-device recognition model and needs a network connection. If the download fails, use the number pad. You can tap Retry ink after you are online, or switch between ink and the pad with the icon in the corner of the bubble.

How do notes work?

In ink mode, write in the top-left (L) or top-right (R) of the bubble. On the pad, tap L or R first, then a digit.

What is the free trial?

You can play on 7 active days at no charge. After that, continued play requires a one-time lifetime unlock. This is not a subscription and does not auto-renew.

How do I restore a purchase?

Open the paywall and tap Restore Purchase. Purchases are tied to your Apple ID.

Where is my progress saved?

Progress and trial status stay on your device. Deleting the app may erase local progress. Purchases remain with your Apple ID and can be restored.

How are refunds handled?

Payments are processed by Apple. Request a refund through Apple (for example, reportaproblem.apple.com). We cannot issue App Store refunds directly.
