Multiplayer Sudoku online
At Sudoku Rivals you can play against another person in real time: you and your opponent solve exactly the same puzzle, each on your own board, and whoever completes it first wins.
How it works
Every multiplayer game deals the same Sudoku puzzle to both players, but each solves it on their own board, independently — you don't see your opponent's cells, only their overall progress. Whoever submits a correct solution first wins.
Matches you against an opponent of similar skill and updates your competitive rating after every game.
