"Unlocking Sudoku: The Art of Seeing the Logic"
Volume 1: Core Principles and Foundational Techniques (This Book)

"Master essential logic and techniques with this step-by-step guide for beginners."

This "how-to" four-volume workbook series is not a collection of mere "tricks" or "shortcuts." Instead, it meets the puzzle on its own terms by providing comprehensive, clear, and patient education in every logical concept and technique needed to solve even the most challenging Sudoku puzzles.

"Unlocking Sudoku: The Art of Seeing the Logic", the series, contains over 1,000 pages of instruction, 40+ dedicated technique chapters, hundreds of large real world example puzzles with concise explanations, and a variety of FAQs after each chapter to further solidify what you just learned. It also features a comprehensive assessment quiz with each chapter that gauges your knowledge of the technique studied. All of this supports the entire learning cycle, from initial discovery to practical application.

We spent many hours deconstructing thousands of Sudokus, from beginner to expert level (and beyond), to ensure we provide engaging, cogent, and thorough explanations for all the essential solving strategies.

Online Support Access: We realize that sometimes there are situations where you just get stuck. You may not see that Swordfish, or X-Wing.
