Sudoku Multiplayer — Race, Co-op & Team Battle
Play sudoku with friends — race solo copies, solve one grid together, or battle team vs. team.
Three ways to play together
Race — everyone solves their own copy of the same puzzle, generated from one shared seed. First to finish correctly wins; everyone else is ranked by how far they got.
Co-op — the whole room shares a single grid. Anyone can fill in any open cell at any time — no turns, no locking each other out. The room wins together the moment the shared grid is fully and correctly solved.
Team battle — pick how many teams (2 to 4) when you create the room; joiners are automatically balanced across them. Each team shares one grid, same as co-op, and races the other teams to finish first.
Coming to iOS and Android
This is the same multiplayer engine that will power the Grandmaster Sudoku apps, currently in development for iOS and Android — for now, play here in your browser.
