About the game
Sudoku gives you a 9x9 grid, cut into nine small squares of 3x3 cells. Some cells already hold a digit from 1 to 9. Your job is to fill every empty cell so that each row, each column and each small square contains every digit exactly once.
You can choose from several difficulty levels, so a quick break puzzle and a tougher brain workout are both on the menu. Mistakes can cost you, so think before you place a number.
How to play
- Click a cell, then click the number you want to put in it.
- Use the Notes button to jot down possible numbers without placing them.
- Each digit from 1 to 9 must appear once per row, once per column and once per 3x3 square.
