About this sudoku book
Twenty medium sudoku puzzles with around 32 given numbers each, printed two to a page so the cells are large enough for pencil marks. They still solve with naked and hidden singles alone, but the singles are harder to find, so expect ten to fifteen minutes each. For adults who have outgrown easy grids.
What’s in the PDF
- Pages 1–10: 20 9 × 9 puzzles, 2 per page (32 clues each), every one with a unique solution.
- Pages 11–14: all the solutions, with the given numbers in bold.
- Black and white, US Letter with 18 mm margins, so it also prints on A4 at 100 % scale.
Tip: Pencil small candidate numbers in the corners of empty cells: at this level, the hidden singles are the whole game.
