Before you write

My progress disappeared

Progress is stored on the device. Reinstalling the game or clearing its data removes it. Tell us your device model and roughly when it happened — we keep anonymous logs that sometimes explain it.

I paid and got nothing

Send the Google Play order number (it starts with GPA.) from the receipt email. Purchases arrive in a later version of the game; if today's build asks you for money, do not pay and tell us immediately.

How do I cancel a subscription?

Google Play → Payments and subscriptions → Subscriptions → SunDoku → Cancel. The current period keeps running; only the next renewal stops.

A level looks unsolvable

Every puzzle is generated with exactly one solution and verified automatically. Send the level number and a screenshot — if a puzzle is genuinely broken, we want to see it.

Ads

There are none. Not between games, not in the shop, not anywhere — the advertising code was removed from the game entirely in September 2026, so there is nothing left that could show you one. If you ever see an ad in SunDoku, please report it: that would be a bug.

Privacy
