Sudoku – Its origin

Sudoku has an interesting history and it is a Japanese term. The word SU means number in Japanese and DOKU means single place on the puzzle board with the aim of fitting every number. It also indicates someone in single. Even though Sudoku is of Japanese origin, it is actually of European and American origin. The game also represents the cross cultural concept. It increases your skills in puzzles and also your IQ level.

How to play Sudoku

First of all Sudoku needs no calculation or arithmetic skills. It is basically a game of placing figures in squares, using very simple rules of sense and deduction. It is very easy to learn and can be played by both children and adults.

Aim of Sudoku

The main aim of Sudoku is to fill the whole empty squares in a game with exact numbers. You have three very simple restrictions to follow. You begin the Sudoku game in a 9 by 9 square: Every row of 9 numbers must include all digits 1 through 9 in any order and every column of 9 numbers must include all digits 1 through 9 in any order. Every 3 by 3 subsection of the 9 by 9 square must include all digits 1 through 9.

In the same way Sudoku puzzle like 4x4 puzzles must have the numerals 1 through 4 in each row, column and subsection. The bigger Sudoku game has 16 by 16 and must have numbers 1through 16 in every row, column and region. All the games have the same rules but the size varies.

The game of Sudoku begins with a number of squares already filled but the only complexity is you have to know how many squares are filled in. The more squares that are filled make the game easier to find out the numbers for Empty Squares. As you fill in squares accurately, choices for the left over squares are tapered and it becomes easier to fill them in. You also get a guide to avoid your going into a wrong path.

Some methods of Sudoku

You need to first look at the rows and columns where you could put correct numbers according to the rules before beginning or attempting a Sudoku puzzle. One more technique is to "pencil in" possibilities and then follow the achievable solutions that appear until a difference is found. Frequently these differences emerge after 2 or 3 numbers are penciled in, and one can come back to the beginning and aim the next option until something clicks.
