What is Sudoku?

Sudoku is a numbers game, which uses logic instead of mathematical skills. The platform of the game is composed of 9x9 grids with 9 rows, 9 columns, all split up into 3x3 squares called regions.

Your objective is to place numbers inside the each empty square with only one number per square. The rules of Sudoku state that every row must contain the numbers 1 through 9. No row may be identical to any other row. The same rule applies to the columns. Additionally, each region must also contain numbers 1 through 9. Duplicate numbers are not allowed in any region. Again, each region will be different from other regions.

Note that some of the squares are already filled with numbers when you start the game. These are called the “givens.” These numbers cannot be changed. The fewer number of squares you need to fill in, the more difficult the game is. Also, the placement of numbers will significantly affect the puzzle’s level of difficulty.

Your task is to complete the squares with no repeated numbers. In solving the puzzle, you need to take note that it already contains one correct answer, and incorrect placement of numbers can keep you from solving the puzzle. Think of a Sudoku puzzle as something that used to be whole and interconnected. Someone has come along and deleted some of the puzzle. This means that the number to be placed on the next square depends upon the numbers on its surrounding squares.

Most people prefer to start from the top of the square when solving the puzzle, but you can begin placing numbers literally anywhere. However, your chances of committing mistake are higher when you begin at the top instead at the bottom or at the center square. It’s best to use a pencil, or play online of course.
