Free printable sudoku

Sudoku is a classic number-placement logic puzzle. You fill a 9x9 grid so every row, column, and 3x3 box holds the digits 1 through 9 exactly once. It suits anyone who likes quiet reasoning, from beginners learning the basics to regular solvers looking for a short break.

This page includes a free high-resolution printable Sudoku image, sized for a 6x9 inch page, plus a matching solution page. Download the PNGs at no cost, print them at home, and enjoy a clean puzzle ready for personal or classroom use.

How to play

  1. Scan the grid for rows, columns, or boxes that already hold many digits.
  2. Place a number only when it is the only option left in that cell.
  3. Never repeat a digit in any row, column, or 3x3 box.
  4. Cross-check your grid against the solution page when you finish.

Print at 100% scale on letter or A4 paper with black ink so the 6x9 inch Sudoku grid stays sharp and easy to write on.
