Book Reviews of Sudoku

Book Review: poorly designed puzzles
Summary: 1 Stars

You might wonder how a sudoku puzzle can be poorly designed...the puzzles in this book violate at least two of the rules in good puzzle design. The first is that a well designed puzzle is symmetrical. You should be able to copy the puzzle and rotate it 180 degrees and the numbers should overlap. None of the puzzles in this book are designed that way. The second rule is that there should be only one correct answer. Many of the puzzles can be completed in multiple ways.

Two great things about the book are the spiral binding...and the main reason I selected it initially...and the small size. It fits in your purse so you have an activity with you all the time.

Summary of Sudoku

Sudoku is a type of logic puzzle that has been popular in Japan for about 20 years. However, the world has caught on to the challenge of sudoku. Sudoku means "single number" in Japanese, but the puzzles are also known as "Number Place" in the United States. Despite using numbers, this is not a mathematical puzzle. Logic skills and a lot of time and patience are needed to solve sudoku.
