Title: From the Board Games Editor at BellaOnline.com
Review: This book is for serious sudoku-ers only! The puzzles are more difficult than those you'd expect from the sudoku books already on the market, but definitely as much, if not more, fun!If you're looking for a gift for your favorite puzzle fan, grab this book. It's pretty new, so chances are, they won't have it.
