180 Puzzles with Two Starter Techniques, a Solving Checklist, and Complete Solutions
Paperback available on Amazon in selected countries
Paperback · 8.5 × 11 inches · 120 pages · black ink on white paper
For adults who know the basic Sudoku rules and want a clear way to practice on paper. The book brings together 180 Easy 9 × 9 puzzles, two short worked examples, a reusable checklist, complete solutions, and a progress log.
Each puzzle has one solution and can be solved using two techniques: a naked single (one number fits a cell) and a hidden single (a number fits only one place in a row, column, or box). No guessing is needed. This is guided practice, not a complete Sudoku course.

Inside the book
Short worked examples explain a naked single and a hidden single before the puzzle section. The checklist near the front uses the same Scan, List, Single cell, Single place, and Update and repeat sequence as our online guide.
Practice grids are large, but the answer key uses compact type. Large print is not used throughout the book.
