Free printable sudoku PDF

• Easy: 50 sudoku puzzles with solutions (PDF, US Letter)
• Medium: 50 sudoku puzzles with solutions (PDF, US Letter)
• Hard: 50 sudoku puzzles with solutions (PDF, US Letter)

How the levels differ

Easy puzzles can be finished with the basic "only one number fits here" moves. Medium puzzles need you to spot pairs and lines that rule numbers out. Hard puzzles need longer chains of those steps. The grading is approximate: a puzzle you find hard may be rated Medium, and the other way round.

Printing tips

• Choose "Actual size" or 100% so the grids stay square.
• Print the first pages only if you do not want the solutions; they start after the last puzzle.
• Need A4, 6 x 9 in, a different number of puzzles or a mix of levels? Use the free sudoku generator.

Use and limits
