How printing works

  1. Choose a mode, a difficulty and how many puzzles you want.
  2. Press Make puzzles and check the previews.
  3. Press Print. The page prints in black and white on its own clean layout, so your browser’s menus and colours never get in the way.

To get a PDF instead of paper, pick “Save as PDF” in your browser’s print window.

Choosing a difficulty

Easy puzzles give plenty of starting digits and can be solved with simple singles. Medium asks you to use pencil notes. Hard gives fewer digits and rewards patterns such as pairs and X-Wing; see Sudoku tips & techniques.

Classic Sudoku

The familiar 9×9 puzzle: every row, column and 3×3 box holds the digits 1–9 once. A good start if you are new; see what Sudoku is.

Diagonal Sudoku

Classic rules plus both long diagonals must also hold 1–9 once. The diagonals are shaded on the printout. Read the Diagonal Sudoku guide.

Killer Sudoku

Killer puzzles print with dashed cages and a target sum in each cage’s corner. Digits in a cage must add up to that sum and cannot repeat. Keep the Killer Sudoku cage combinations cheat sheet beside you while you solve.

Prefer to play on screen?

The same puzzles are playable online with notes, undo and hints. You can also print the puzzle you are playing from the printer button on the game board.
