Solving Sudoku Puzzles are brain teasers which have also been identified as wordless crossword puzzles. Sudoku Puzzles are usually solved through inventiveness and have been building a great impact all across the world.
Also known as Number Place, Sudoku puzzles are in fact logic-based assignment puzzles. The object of the game is to enter a numerical digit from 1 through 9 in each cell that is found on a 9 x 9 grid that is subdivided into 3 x 3 sub grids or regions. Many numbers are mostly given in certain cells. These are referred as givens. Ideally, at the end of the game, every row, column, and region have to contain only one instance of each number from 1 through 9. Patience and judgment are two traits required so as to end the game.
Number puzzles quite similar to the Sudoku Puzzles have already been in existence and have found publication in many magazines for over a century now. For instance, Le Siecle, a daily newspaper based in France, featured, as early as 1892, a 9x9 grid with 3x3 sub-squares, but used only double-digit numbers instead of the present 1-9. One more French newspaper, La France, established a brainteaser in 1895 that utilized the digits 1-9 but had no 3x3 sub-squares, but the solution does carry 1-9 in each of the 3 x 3 areas where the sub-squares would be. These puzzles were regular features in several other newspapers, as well as L'Echo de Paris for about a decade, but it unluckily disappeared with the advent of the First World War.

Howard Garns, a 74-year-old retired engineer and freelance puzzle constructor, was regarded as the inventor of the modern Sudoku Puzzles. His design was first published in 1979 in New York by Dell, through its magazine Dell Pencil Puzzles and Word Games under the headline Number Place. Garns' creation was most likely motivated by the Latin square discovery of Leonhard Euler, with some modifications, mainly, with the addition of a regional restriction and the presentation of the game as a brainteaser, providing a partially-complete grid and requiring the solver to fill out the blank cells.
Sudoku Puzzles were then taken to Japan by the puzzle publishing company Nikoli. It launched the game in its paper Monthly Nikoli sometime in April 1984. Nikoli president Maki Kaji gave it the name Sudoku, a name which the corporation holds brand rights over; other Japanese publications which featured the puzzle have to settle for other names.
In 1989, Sudoku Puzzles entered the video games arena when it was available as DigitHunt on the Commodore 64. It was initiated by Loadstar/Softdisk Publishing. Since then, other computerized versions of the Sudoku Puzzles have been established. For instance, Yoshimitsu Kanai made several computerized puzzle generator of the game under the name Single Number for the Apple Macintosh in 1995 both in English and in Japanese language; for the Palm (PDA) in 1996; and for Mac OS X in 2005.
