Automated Sudoku: Sudoku Puzzles Made Easy

The game of Sudoku doesn't need an introduction; there's at least one of these wordless puzzles in every newspaper or magazine. But author Alan Ross has provided a unique format in his new book, Automated Sudoku.

Designed and tested by a computer program created by Ross, this edition boasts nearly 500 puzzles, of which 400 are evaluated as difficult. In each game, Ross has included all possible answers for each square so the puzzle solutions are based on logic and not trial and error.
