Sudoku 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 contains all of the digits from 1 to 9, only one time each (that is, exclusively).
The puzzle setter provides a partially completed grid. The general way to solve the problem is when you insert a new number it should be unique in that particular region (box) and also in that particular row and column.
The 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 where the language is not suitable for crosswords. It was later published by Nikoli and given the name Sudoku, meaning single number. It became an international hit in 2005.
