Both paper sizes contain the same six puzzles. No account or email address is needed to download the files.
What is inside this collection?
Collection 01 contains six original 9 × 9 grids generated for Sudoku iLove. We have checked that each puzzle has exactly one solution and that every starting clue agrees with it. These are public practice puzzles, separate from the scored daily challenge catalogue.
Pages 1, 2 and 3 contain the easy, medium and hard puzzles respectively. Page 4 collects all six solutions, matched by puzzle number. Each playing page has two large grids with clear boundaries around the 3 × 3 boxes and room inside the cells for pencil marks.
How to print without seeing the answers
Open the PDF that matches your printer paper. Print only pages 1 to 3 for your first session, and leave page 4 until you are ready to check your answers. Choose portrait orientation and check the print preview before sending the pages to your printer.
The grids work in black and white. Printing at 100% preserves the intended size; if the preview cuts off an edge, choose fit to printable area. A pencil makes it easier to update candidates and correct a misplaced digit without starting the page again.
Choose a level by its solving techniques
Our logical rater solves the easy grids with naked singles. Medium puzzles also need hidden singles. Hard puzzles introduce locked candidates or naked pairs. These labels describe a path found by the rater, rather than a promised completion time or a universal difficulty standard.
New to Sudoku? Start with the easy page. Every row, column and 3 × 3 box must contain the digits 1 to 9 without repetition. Check all three units before committing to a number. Sudoku uses logical elimination; there is no arithmetic to calculate.
Before you print
Are the PDFs free?
Yes. Download without signing up and solve offline. A4 and US Letter change the paper size, not the puzzles.
Where are the solutions?
