Play classic 9x9 Sudoku online free with daily and unlimited puzzles. Place the numbers 1 to 9 so that every row, column and 3x3 box contains each number once.
Select an empty cell and use the built-in number pad to enter a value. Pencil marks help you track candidates, while Undo and Clear Cell let you revise your working without changing the original clues.
One optional hint can fill a correct cell for you. Duplicate values are highlighted when a row, column or 3x3 box is complete.
The signed-in daily Sudoku puzzle changes at midnight UTC. Progress is saved after you begin, and the server tracks active solving time rather than counting time spent away from the page.
Complete the puzzle to extend your Sudoku streak, or use unlimited mode for additional randomly generated boards.
Daily completions earn 6 points in 5 minutes or less, 5 in 10 minutes, 4 in 15, 3 in 20, 2 in 30, and 1 point after 30 minutes. Using a hint reduces the score by 1 and caps it at 4 points.
Daily Sudoku leaderboards rank faster valid completions higher. Unlimited results count towards your game statistics but do not award points.
