Printable Sudoku Puzzles (Deluxe Version)
Generate unlimited free Sudoku puzzles with varying degrees of difficulty!
Sudoku is a great activity to sharpen the mind. The object of Sudoku is to fill in the empty spaces of a 9x9 grid with numbers 1-9 in such a manner that every row, every column and every 3x3 box contains all numbers 1 through 9. It's fun and challenging for all ages. We also have 4x4 Sudoku for younger kids and 16x16 (Hexadoku) Sudoku for the enthusiast who wants a real challenge!
Choose from a large single puzzle, 4 medium or 9 small puzzles per page. You can also choose your difficulty and page title. After printing the puzzle(s), simply close the window and generate and print the KEY for that Sudoku.
Fun Addition: Our printed puzzles are highly customizable and can also be printed with 'candidates' (i.e. available numbers for each cell) and we also compile a list of the strategies that it takes to solve each Sudoku Puzzle that you can add to each puzzle.
