Sudoku, also known as Number Place or Nanpure, is a logic-based placement puzzle. The object is to fill the grid so that every column, every row and every 3?3 box contains the digits 1 to 9. The puzzle setter provides a partially completed grid so that there is only one solution. Completed Sudoku puzzles are 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, 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.
If you want to play this game offline and without any browsers after December 2020, then download .swf game file and use any Flash Player that runs .swf files.
For Windows users, I recommend ARFlashPlayer (it supports fullscreen option) or official Adobe Flash Player. Both programs are portable.
Another way to play flash games is to install SuperNova SWF Extension (it works in Chrome only).
