About this sudoku book
Twenty expert-level sudoku puzzles with only 24 to 26 given numbers each, two per page. Every grid has exactly one solution, verified by our solver, and none can be cracked with singles; expect chains, X-wings and the odd educated guess. They are for solvers who finish newspaper ‘hard’ grids without slowing down.
What’s in the PDF
- Pages 1–10: 20 9 × 9 puzzles, 2 per page (24 to 26 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: Write every candidate in every empty cell before you start; with so few clues, full pencil marks are faster than trying to hold it all in your head.
