The Sudoku Addict's Workbook : Become a sudoku-solving whiz! Sudoku guru Paul Stephens (Mastering Sudoku) has devised a skill-building workbook that can take you from average to confidently advanced in no time. His comprehensive how-to features a selection of foolproof techniques, along with 150 hand-picked puzzles (self-generated from his own computer program) specially chosen to provide practice in key strategies. Each puzzle has an introductory profile, expert tips for extra guidance, and a grade-yourself time score. On the solution pages, Stephens has highlighted many key solving patterns - an ingenious way to help newcomers master even difficult puzzles. A 10-page introduction covers all the major techniques from pairs and triples to X-wing, swordfish and non-unique rectangles. Sudoku has never been so much fun!
