Welcome to A Journey through Classic Sudoku Techniques! Within your journey, you will discover over seventy sudoku techniques! Use them to reveal the mysteries of even the most difficult sudoku puzzles.

There's hidden singles to ALS chains and tons of techniques in between! This guide is for everyone from the true beginner all the way to the seasoned solver. Whether you play casually, you have been playing for years, or you have never tried a sudoku puzzle before, there is something here for you.

Each chapter requires you, the solver, to think about puzzles differently. Each chapter also serves as a foundation for the next. For example, it would be difficult to work on chapter 3 without working on chapter 2 first. Therefore, it is important to go through each chapter in order.

Finally, within each chapter, there is a difficulty scale. The range is based on the difficulty of the subject. Spoiler alert: Chapter 8 has five 10/10 difficulty techniques! However, you can do it! Just go one technique after the other, one step at a time.

Cheers and happy solving!
