Common questions
Is Orbace Sudoku free?
Orbace Sudoku can be downloaded without an upfront purchase. The applicable app-store listing identifies advertising, optional purchases, or other current commercial features.
What features are available in the app I can download today?
The App Store and Google Play listings describe the build available today. Features vary by platform and app version, and the listing is authoritative.
Can I play without an account?
Yes. Personal play is designed to work without an Orbace account. Saved records across devices and official competition require sign-in.
What is Su-Pu?
Su-Pu (数谱) is Orbace’s move-by-move record of a solve. It lets you replay how the grid opened rather than only seeing the finished puzzle.
Does progress synchronize between devices?
Information stored only on one device does not automatically move to another. A feature must explicitly support synchronization before you rely on it.
Where can I get support?
Visit the Contact page and include your device, operating system, app version, and puzzle ID where relevant.
