Welcome to Sudoku Special

Sudoku (数独) is a logic-based number-placement puzzle. The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 boxes (also called blocks or regions) contains the digits from 1 to 9 only one time each. The puzzle setter provides a partially completed grid.

Completed Sudoku puzzles are usually a type of Latin square with an additional constraint on the contents of individual regions. Leonhard Euler is sometimes incorrectly cited as the source of the puzzle, based on his work with Latin squares.

The modern puzzle was invented by an American architect, Howard Garns, in 1979 and published by Dell Magazines under the name "Number Place". It became popular in Japan in 1986, after it was published by Nikoli and given the name Sudoku, meaning single number. It became an international hit in 2005

The name Sudoku(数独) is short for "数字は独身に限る" which is read, "Sūji wa dokushin ni kagiru", meaning "the numbers must be single", or "the numbers must occur only once".

The numerals in Sudoku puzzles are used for convenience; arithmetic relationships between numerals are irrelevant. Any set of distinct symbols will do, such as letters, shapes, or colours. In fact, ESPN published Sudoku puzzles substituting the positions on a baseball field for the numbers 1 to 9, while Viz magazine has published a Doctor Who version of the game, using images of the television series' first nine leading actors in place of the numerals. Dell Magazines, the puzzle's originator has been using numerals for Number Place in its magazines since they first published it in 1979.
