Sudoku · How to play

Sudoku arranges nine digits under three overlapping constraints: rows, columns and boxes. This version uses cell selection and a number pad for gradual, touch-friendly deduction.

Controls

Use the touch-friendly game controls. Detailed rules appear below the board.

Rules & goal

  • Fixed clues cannot be edited. Fill blank cells with digits from 1 to 9.
  • Every row, column and three-by-three box must contain each digit without repetition.
  • Complete the correct grid to finish; Clear removes the entry in the selected blank cell.

Beginner tips

  • Start with a row, column or box that has only a few missing digits.
  • Check all three constraints instead of accepting a digit merely because its row allows it.

Progress & devices

Play in a desktop or mobile browser using the controls above. Some games save only in the current browser; clearing site data can remove saves. Pause when stepping away. Reloading is not guaranteed to preserve the current round.
