What you will get
Each download is a printable Sudoku booklet. Six puzzles render per page in a 2×3 grid, so spacing stays consistent on paper. If you turn solutions on, the PDF adds a separate page with completed grids that mirrors the puzzle layout.
How printing works
- Six puzzles render per page in a 2×3 grid for consistent layouts.
- Switch paper size between A4 and US Letter to match your printer.
- Unique solutions enforces a single-solution puzzle via an internal solver.
- Include solutions to add a separate printable page with completed grids.
How the generator works
The tool builds a fully solved 9×9 grid first, then removes cells based on your difficulty choice. Easy keeps more givens visible. Hard removes more cells, leaving more deduction work. The unique-solutions toggle runs a solver in the background and rejects any puzzle that has more than one valid completion.
Helpful tips
- Use mixed difficulty to print a varied set for a class or commute pack.
- Print a single test page first to confirm scale is set to 100%.
- Keep solutions on while teaching, off when handing out for play.
Limits to keep in mind
Difficulty is based on the number of removed cells, not on hand-curated logic. Very small puzzle sets may repeat patterns; generate a fresh batch for variety.
