Sudoku has been gaining popularity by the day since around 2005 and if you think Sudoku is a Japanese past-time, think again! The modern puzzle was invented by an American architect called Howard Garns, in 1979 and published by Dell Magazines under the name "Numbers in Place.”
It was later popularized ( in 1986 ) by the Japanese puzzle company Nikoli, under the name Sudoku, which means ‘single number’ and it became an international hit in 2005.
For the uninitiated, a sudoku is a is a logic-based placement puzzle.
A sudoku puzzle consists of nine 3×3 grids arranged in a square, some of them already filled out with numbers. The goal is to fill out the rest according to the ultimate rule: in every row, in every column, and in every 3×3 grid, there must be the numbers 1 to 9. This means that in those three confinements, any number does not repeat.
Though there is no mathematics involved, it is not as simple as it may sound. There are various strategies one can use to solve a sudoku but there are also trap-doors – for instance, once you make a mistake in a sudoku puzzle, it is very difficult to trace your mistake.
