Description
Instructions: Use your mouse to play this game.
Sudoku Classic is the number puzzle in its familiar form. A 9x9 grid, some numbers given, and your job is to fill the rest without repeating a digit in any row, any column or any of the nine boxes.
Pencil marks help with hard grids, and a magic wand is there if you get stuck. You can pick a daily challenge or choose a difficulty. It is filed under Numbers and plays on phones too.
Sudoku rules
Complete the grid using the digits 1 to 9. No line, column or small box may hold the same digit twice. Use markings to note possible numbers in a cell while you work it out. If you are really stuck, the magic wand can help.
Sudoku solving tips
- Start with rows, columns or blocks that already have many numbers.
- Use markings to keep track of candidates, especially in hard grids.
- If a number can only go in one cell of a block, place it right away.
