Common questions
Is Orbace Sudoku free?
Orbace Sudoku Free can be downloaded without an upfront purchase. The applicable app-store listing identifies advertising, optional purchases, or other current commercial features.
Can I play without an account?
Core features in the lightweight app are designed to work without a connected Orbace account. Rankings, tournaments, synchronization, or other connected features may require sign-in.
Does offline play synchronize between devices?
Information stored only on one device does not automatically move to another. A connected feature must explicitly support synchronization before you should rely on it.
What is a Su-Pu?
A Su-Pu is Orbace’s replayable, move-by-move record of a Sudoku solve. It helps you revisit decisions and see more than the completed grid.
Where can I get support?
