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.
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.
