How do hints work?

Each game includes 3 free progressive hints. A hint explains the next logical step without guessing. If you want hints without a per-game limit, you can unlock unlimited hints for life with a one-time in-app purchase.

How do unlimited hints work?

After the unlock is purchased, the hint button stays available even after the 3 free hints are used. The unlock is a lifetime non-consumable purchase tied to your App Store account.

Does auto-solve reduce my score?

No. Auto-solve only appears when the remaining cells are obvious singles. It finishes those cells one by one to speed up the end of the game and does not reduce your score.

Is my progress saved?

Yes. Your current game, timer, notes, and local stats are saved on your device.

How do I report a problem?

Email tomhrt50@gmail.com with your device model, iOS version, app version, a short description of the issue, and a screenshot if useful.
