That means that every row, every column and every block has 9 cells. There are 81 cells in total in a 9 X 9 Sudoku grid.

Boxes Or Blocks

Boxes or blocks are shown with thicker lines to make them clearer.

  2. Every column contains one and only one of the 9 symbols used
  3. Every block (or box) contains one and only one of the 9 symbols used.

Playing Sudoku

A Sudoku puzzle is one that presents the player with a grid containing some numbers. There should be enough numbers (clues) included to ensure that the sudoku puzzle is a “proper sudoku”, that is, it has only one correct solution. The aim is to complete the grid so it includes all the symbols / numbers, following the 3 rules. So, only one of each symbol in any row, column or block.
