Compete against your friends in realtime on the same Sudoku board. Be quick, or they'll steal your squares. You get one point for every square you fill in, and you lose two points if you enter a number incorrectly. Let the battle begin.

Don't have any Sudoku-playing friends? That's okay, you've still got options. Plan A: get your friends to download Sudoku Compete and cream them with your ultimate Sudoku skills. Plan B: play online against a random opponent. Plan C: play Sudoku the traditional way in single-player mode.

Battle for the top places on the monthly leaderboard or just play to keep track of how many games you've completed, your win rate, and lots of other statistics!
