Playing with numbers!

Yes! Talking about numbers makes me sick! But hey not with Sudoku! It seems odd that I've never liked Maths since I was a kid and so I flunked them few times at school. My brain just can't think of any ways to solved Maths problem in a quickest and easiest way. I need a brain wash everyone!

 I used to play Sudoku on newspapers... talking about old times eh!

So listen here, Sudoku involves combination of numbers (see what I meant!). In Sudoku, the goal is to load a 9x9 square grid (nevertheless, other variant emerge). Also, each column and each row encloses a 3x3 sub grid, which agrees to a maximum of 9 numbers to be supplemented to every box. Sounds easy, doesn't it? But the hitch lies here, you can have only one solution, you cannot repeat a number in a horizontal line, vertical line on in a square!

 I missed doing this on the paper

Now, let us look at the origin of Sudoku first. Sudoku, which has been called the Rubik's Cube of the 21st century, was designed by Howard Garns, who was a retired architect and a freelance puzzle constructor. He published his first puzzle in 1979.

Garns was the first to present the square as a puzzle, when he would provide a grid that was partially completed, and have the user fill in the answers. Dell Magazines published the puzzle in its magazine called Dell Pencil Puzzles and Word Games. The game was originally called Number Place.

The puzzle was then found in Japan by Nikoli, in a paper called Monthly Nikolist, which came out in April of 1984. The puzzle was called Suuji wa dokushin ni kagiru. This means, 'the numbers must occur only once.' Later, the name was abbreviated to Sudoku, in which the Su means number and the Doku means single.

Then, the game was changed yet again, as in 1986 some rules were given. The number of givens was reduced to no more than 32, and the puzzles became symmetrical. The first computer version of Sudoku was produced in 1989 for the Commodore 64. In 1995 and 1996, Japanese publisher Yoshimitsu Kanai published more computer generated puzzles for Sudoku.

Once I did a brief research on Sudoku, I've never wondered myself that it started from America not Japan.
