Why Use a Blank Sudoku Grid?
An empty Sudoku grid is one of the most useful tools a solver can keep on hand. The most common use is transcribing puzzles: copy a puzzle from a newspaper, magazine, or puzzle book onto a fresh grid so you can solve it in clean handwriting — or attempt it a second time after making mistakes. Once you've transcribed a puzzle, you can also solve the puzzle you've transcribed with our Sudoku solver to check your answer or get unstuck.
Blank grids are equally good for practicing techniques. Set up a specific pattern — an X-Wing, a naked pair, a pointing triple — and work through the elimination logic by hand until it sticks. Teachers use empty grids the same way: print a stack, write a handful of given digits on the board, and let students copy and solve at their own pace. It's a cheap, screen-free classroom activity that needs nothing but a pencil.
Looking for grids that already contain puzzles? Our printable Sudoku puzzles page generates ready-to-solve sheets at six difficulty levels, and the free Sudoku generator creates unlimited fresh puzzles you can solve on screen or print.
Candidate Boxes for Pencil Marks
The "with candidate boxes" layout prints a faint 3×3 dot guide inside every cell. Each dot marks where a candidate digit 1–9 belongs, so your pencil marks stay tidy and readable even deep into a hard puzzle. If you're new to candidate notation, our guide to notes in Sudoku explains how to write and prune pencil marks effectively.
Printing Tips
- Print at 100% scale — "fit to page" distorts the square cells.
- Enable background graphics in your print dialog for crisp 3×3 borders.
- Use the 1-grid layout when you need maximum writing space, and the 4- or 6-grid layouts for practice sheets or classroom handouts.
- A4 and US Letter both work; the grids scale to either paper size.
