This review is from: Killer Sudoku: 100 easy to hard puzzles and how to solve them (Paperback)
Jana Thorpe Schmidt's review is good. This book has a well done introduction - clearly explained, nice graphics. I gave it a fifth star for the introduction. I've been doing killer sudoku for over a year. The introduction helped me discipline myself to work methodically through a puzzle. Plus, it hadn't dawned on me that 1-9 added together equal 45! The introduction revealed this fact and that has helped me. It has a complete numbers combination sheet which is extremely helpful.
Two puzzles per page. Nice quality paper. The puzzles are big enough to put possible combinations in the spaces. It is easy to distinguish the grid lines, dotted lines, and number clues.
The puzzles are divided into three sections - easy, medium, hard. If you're new to killer suduko, the easy are actually medium.
