About this sudoku book
One hundred hard sudoku puzzles, two to a page so there is room for pencil marks. Each grid has around 27 given numbers and a unique solution, and none can be finished with singles alone, so you will need pairs, pointing candidates and patience. It is a month or two of daily puzzles for an experienced solver, in one PDF.
What’s in the PDF
- Pages 1–50: 100 9 × 9 puzzles, 2 per page (27 clues each), every one with a unique solution.
- Pages 51–67: 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: Number your sessions: solving one puzzle a day in order, you will notice your time dropping by the fourth week.
