Brief History Of Sudoku

The modern form of Sudoku was invented in the late 1970's by an American puzzle maker by the name of Howard Garnes. His puzzle, termed 'Number Place', appeared in a 1979 publication by Dell Magazines but wasn't an immediate success and certainly not the worldwide phenomenon we see today.

Instead, it took the Japanese to make 'Number Place' a success when it was published by Nikoli in 1986 under the name of sudoku (a shortened version of the phrase Suji wa dokushin ni kagiru) which roughly translates as "the numbers must remain single" or "the numbers must occur only once"...which is ultimately the general rule of the puzzle.

Sudoku hit worldwide popularity around 2005 when a succession of national newspapers, websites and other publications jumped on the bandwagon and made this one of the world's most popular logic puzzles.

How To Play Sudoku

Rules and Introduction For Sudoku Beginners

Many people are put off by the numbers appearing on the sudoku grid, automatically assuming there is some kind of maths or calculation involved before getting to know the rules.

Rest assured, sudoku doesn't require you to be a mathematics genius to play and in fact, there are many sudoku variations out there which do not even use numbers at all.

Instead, sudoku requires a combination of logic and deduction and can be enjoyed by both children and adults as the rules are very simple to learn.

If you can place numbers in squares, you can play sudoku.

The Objective and Rules of Sudoku

The basic sudoku grid has 81 squares, consisting of 9 rows, 9 columns and 9 smaller 3x3 blocks.

Some of the numbers which will comprise the solution to your sudoku puzzle are given, the rest you will have to deduce by following a set of three rules.

1. Every row must consist of every number 1 through 9 with no duplication.

2. Every column must consist of every number 1 through 9 with no duplication.

3. Every 3 by 3 block must include every number 1 through 9 with no duplication.

There are larger and smaller sudoku puzzles but whatever the size, the rules remain the same. For example, in a 16x16 puzzle (256 squares), the numbers 1 through 16 are used instead, but the rules for filling in the squares remain the same.
