, also known as Number Place or Nanpure, is a logic-based placement puzzle. The aim of the puzzle is to enter a numerical digit from 1 through 9 in each cell of a 9×9 grid made up of 3×3 subgrids (called "regions"), starting with various digits given in some cells (the "givens"); each row, column, and region must contain only one instance of each numeral. Completing the puzzle requires patience and logical ability. An early variant of the puzzle was published in a French newspaper in 1895 and may have been influenced by the great Swiss mathemetician Leonhard Euler, who repopularized Latin squares.
Though Euler is frequently misrepresented as being the origin of either game, in fact Latin Squares are frequently engraved in architecture as a numerological talisman, some several thousand years old; and Euler made no changes to their rules. Arabic Numerologists had already compiled an exhaustive list of order 3 through order 9 Greco-Latin Squares in the Jabirean Corpus by 990 AD.
The modern game Sudoku was invented in Indianapolis in 1979. Interest in Sudoku stems from a revival in Japan in 1986, when the venerable puzzle publisher Nikoli discovered the game as invented by Howard Garns and initially distributed for children under the name "Number Place" in an older Dell Magazines publication, and republished the format leading to widespread international popularity in 2005.
