More Original Sudoku

Over twenty years ago Nikoli, the Japanese puzzle and game company, started publishing a curious logic puzzle called Sudoku. The rest of the world recently joined the Sudoku craze by using computer programs to create puzzles, but Nikoli is the only company that still crafts their puzzles the old-fashioned way: by hand. An obsessive’s collection, More Original Sudoku features over 300 puzzles, all in a chunky, easy-to-carry format (it even fits into a standard jeans-size back pocket). An introduction shows how to solve the puzzles at various levels of difficulty, and it includes a tutorial on how to create your own hand-made Sudoku.
