Hi HN, I’m a Sudoku enthusiast and built PrintableSudoku.net to make it easy for anyone to download printable Sudoku PDFs or play puzzles online. You can choose difficulty, print as many as you like, or solve directly on the site. I wanted something straightforward for people who enjoy Sudoku, whether on paper or online. Any thoughts or suggestions about the puzzles or the site are very welcome!
