Not the hardest of the puzzles, but certainly math problems that anyone can do

Sudoku is a puzzle that is very simple in form and has taken the world by storm. A nine-by-nine matrix is created and split into nine different three-by-three sections. Each three-by-three section is to contain the numbers one through nine and no row or column must have more than one instance of the same number. You are given some of the entries and the goal is to fill in the remaining entries. This book is a collection of 300 such puzzles and solutions are included at the end. The first eight pages are a history of the puzzle as well as a description of solution strategies. They are fairly simple and easy to understand, which in part explains why the puzzle is so popular. To appeal to a mass audience, the masses must be able to understand and solve the puzzle. I enjoyed working the few puzzles that I went through. While not hard, they do require that you think and that is always a good thing to do. My thirteen year old daughter Katrina also loves doing these puzzles, she does them by the hour. I don't think it is a coincidence that her math grades have gone up since she started working them. Published in Journal of Recreational Mathematics, reprinted with permission

Great variety - from easy to challenging. The grids are an ideal size to scribble cheat notes within the cells. All puzzles are numeric.

I love Sudoku and this book! I just received it today from my best friend and we were solving it at my house, and now I'm working on it. I've already solved one! Yay! They're really challenging but very fun and great to get the brain moving. Have fun with it! ~Livi~
