About Sudoku
Sudoku provides compact, standard, and larger logic grids with three difficulty levels. Enter firm answers or pencil-mark notes, follow peer highlights, and resolve the puzzle through row, column, and box constraints.
Rules in brief
How to play Sudoku
- 01
Choose an empty cell and enter a digit that does not duplicate another digit in the same row, column, or outlined box.
- 02
Use note mode to record candidates while you compare constraints across the grid.
- 03
Complete every cell correctly to finish; no arithmetic is required, only elimination and pattern recognition.
