Play Sudoku Online
The modern puzzle was invented by an American, Howard Garns, in 1979 and published by Dell Magazines under the name Number Place. It became popular in Japan in 1986, when it was published by Nikoli and given the name Sudoku. It became an international hit in 2005.
The attraction of the puzzle is that the rules are simple, yet the line of reasoning required to solve the puzzle may be complex. The level of difficulty can be selected to suit the audience. The puzzles are often available free from published sources and may be custom-made using software.
