Play Sudoku & Give Your Brain a Workout

Sudoku seems to be all the rage – people are playing it just about everywhere you might go.

It is one of the things that people do in airports, train stations, or in their spare time to keep themselves occupied.

Sudoku seems like a simple thing when you glance at it at first – no buttons or whistles or even colors – but in reality, Sudoku is something that can be challenging and fun for anyone's set of talents.

Sudoku is very popular because it is a game that challenges your brain, and makes you think in order to win. It can also be quite addictive!



The History of Sudoku

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.

The Sudoku puzzle was probably inspired by the Latin Square invention of Leonhard Euler. However, Garns himself added a third dimension, which was the regional restriction.

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.

Later, 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.

Dell Magazine again picked up the thread, and currently publishes two Sudoku magazines.


How to Play Sudoku

On the surface, it is easy to learn how to play Sudoku, as long as you know the basic rule. The Sudoku square is all you will need, along with a pencil or a pen to fill in the numbers. It is a good idea to start with a pencil!

When you look at the Sudoku square, you'll see that there are 9 small squares across, and 9 small squares going down the line. Some of the squares already have numbers in them, but most of them are blank. The ones that have numbers in them are answers that you can trust. They are already done for you.

The rules to Sudoku are very simple. You must fill in the numbers 1-9 in each of the squares. Each square in a row must have all of the numbers from 1 to 9, and cannot have any numbers that repeat. All of the numbers going across must be from 1-9, and all of the numbers going up and down must also be from 1-9.

In order to complete a game of Sudoku, you have to make sure that each of the rows, whether they are horizontal or whether they are vertical, have the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 in them. Once you have done one row, you should move on to the next one. Remember, the numbers that have been put into the boxes for you are numbers that are correct.

Also, the other important rule to remember is that within the Sudoku square, there are smaller squares. In each of these smaller squares, you will only have the numbers 1-9. This also makes the puzzles easier to solve.

Sudoku Tips

There are several ways that you can play Sudoku, and finding some great tips to help you is something that you might want to think about .

A great tip to start with is to take your Sudoku square and use a pencil to pencil in all of the numbers that might occur in a single square. Taking a look at the numbers that already exist in both the vertical row and the horizontal row that a square is part of, you'll be able to come up with the numbers that could go in that square. If you do that, you will end up with some squares that only have one number as a possibility. Once you've found that, you have solved the number for that square.

For instance, if you have four squares open in row, and the possibilities are 1,7 and 2,7 and 7 and 1,9, you know that the square that only has 7 for a possibility is solved. By elimination, you also know that the 1,7 square must be a 1, and the 2,7 square must be a two. Already, you have three out of the four square solved. Then, since you have already put 1 in a square, you also have the last square solved.

Also, if you really want to become great at solving sudoku puzzles, then you should really buy yourself a sudoku book. It's one of those tine books with hundreds of sudoku puzzles inside. Ranging from easy to hard.

You are going to get very good at solving sudokus if you keep trying. Plus, your brain will improve its logic and problem solving ability which you can use to your advantage in your every day life. That's pretty cool!
