Sudoku

Play Sudoku online in your browser, fill every row, column, and 3x3 box with digits 1 through 9, then settle into a clean solving rhythm.

• Tap any open cell, then use the keypad or number keys. Press M or tap Notes for pencil marks.
• Wrong digits are rejected, so keep pressing forward instead of cleaning up bad guesses.
• Hint reveals add time, and both best times and active board progress save on this device.
