eSudoku is the fastest open source logical sudoku solver

Sudoku is a global phenomenon. The logical 9x9 numerical puzzle was initially developed by an American before gaining popularity in Japan. Now the whole world has taken notice.

eSudoku uses logic to solve puzzles rather than the crude brute force attacked favoured by other programs. And that's why it is the fastest, and the best. It is written in C so is very powerful.

eSudoku also teaches you how to solve sudoku puzzles as it does not just give you the answer to a puzzle - it shows you how it calculated the answer aswell!
