Blank sudoku grid

Four empty 9×9 grids, sized for A4. Use them to hand-solve a puzzle you found elsewhere, to teach, or to design a puzzle of your own.

How to use them

  • Print at 100% scale — the grids are 80 mm square, which fits four to a page with room for pencil marks.
  • For pencil marks, most solvers use a 3×3 mini-grid inside each cell; the printed cell is large enough for that.
  • Making your own puzzle? Fill a grid completely, then erase digits one at a time, checking after each removal that the solution is still unique.
