## Sudoku Game

**Sudoku**

is a logic-based puzzle.

It is a type of

*constraint satisfaction problem*, where the solver is given a finite number of objects (the numerals 1-9) and a set of conditions stating how the objects must be placed in relation to one another.The puzzle consists of a 9×9 grid further divided into nine $3$×3 sub-grids (also called boxes, blocks, regions, or sub-squares).

The objective is to place the digits within the grid so that each column, row, and sub-grid contains all of the digits from $1$ to 9. Each puzzle is published with some of the boxes already filled in, and those constraints help define the problem's difficulty level.

People sometimes say

*there is no math required to solve Sudoku*.What they really mean is, there is no

*arithmetic*involved in Sudoku. Mathematical thinking in the forms of deductive reasoning and algorithms are the basic tools for solving Sudoku puzzles.
