What is Sudoku?
Sudoku is a free online logic puzzle where you fill a 9x9 grid so every row, column, and 3x3 box contains the numbers 1 through 9 once.
Sudoku Tips
- Start with rows, columns, or boxes that already have the most numbers.
- Use elimination before guessing; each empty cell has a limited set of possible numbers.
- Scan one number at a time across the whole board to find forced placements.
