Printable Sudoku Puzzles (Legacy Version)

Generate unlimited 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.

You are currently on the page to make our Legacy Sudoku Puzzles. These 9x9 Sudoku puzzles generate quick! Difficulty is determined by removing numbers from a completed grid - the more numbers we remove indicates a harder difficulty. Please NOTE: on occasion this may create puzzles that have more than one solution. The only way to tell if a Sudoku puzzle has only one solution is to solve it (behind the scenes), which takes time. Our Deluxe Sudoku puzzles provide "Genuine Sudoku" puzzles but take longer to generate because we analyze each puzzle extensively before delivering it to your printed page.

Choose from a larger single puzzle, 2 medium puzzles or 4 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.
