Wait, You don't know the rules of sudoku?
I guess this is your first time solving sudoku puzzles. Read VERY carefully.
Numbers are used in Sudoku. A number is an arithmetical value, expressed by a word, symbol, or figure, representing a particular quantity and used in counting and making calculations.
There are 10 Numbers we use everyday.
0 1 2 3 4 5 6 7 8 9
0 is not a digit used in normal sudoku.
The Digits used in sudoku are
1 2 3 4 5 6 7 8 9
We write these digits in a "Cell"
The sudoku grid is made up of 81 Cells. These cells are placed in such a way that there are 9 cells every row and 9 cells in every column. So a 9x9 Square.
You are NOT allowed to repeat digits in any ROW and COLUMN.
Furthermore, the 9x9 Square is split into nine 3x3 squares placed in such a way that there are three 3x3 squares in every row and every column.
We call these 3x3 Squares "3x3 Boxes". You are NOT allowed to repeat digits in a 3x3 box.
These are the Normal sudoku rules.
