Printable Jigsaw Sudoku Puzzles

Jigsaw sudoku (also called squiggly sudoku or irregular sudoku) formatted for paper. Each sheet shows one puzzle with thick borders marking the irregular region boundaries. Use your browser's Print function or Ctrl+P / Cmd+P to save as PDF.

Printing tips: The grids use thick lines (2.5pt) for region boundaries and thin lines for cell borders, so they print well in black and white. If your printer supports color, the region borders will be even clearer. Set margins to "minimum" in your print dialog for the best fit. Answer keys are available on the interactive version at thepuzzlelabs.com/jigsaw-sudoku.
