Understanding What Really Sudoku Puzzle Is

 

 

Solving Sudoku Puzzles are brain teasers that have also been called wordless crossword puzzles. Sudoku Puzzles are often solved through inventiveness and have been making a large impact all across the world.

Even referred as Number Place, Sudoku puzzles are actually logic-based placement puzzles. The object of the game is to enter a numerical digit from 1 through 9 in each cell which is found on a 9 x 9 grid which is subdivided into 3 x 3 sub grids or regions. Several numbers are frequently given in some 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. Persistence and logic are two qualities needed in order to complete the game.

Number puzzles quite similar to the Sudoku Puzzles have already been in existence and have found publication in several newspapers 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 figures instead of the current 1-9. One more French newspaper, La France, formed a puzzle in 1895 that utilized the numbers 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 brainteasers 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 considered the designer 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 creation of Leonhard Euler, with a few modifications, basically, with the addition of a regional restriction and the presentation of the game as a puzzle, giving a partially-complete grid and requiring the solver to fill in the empty cells.

Sudoku Puzzles were then taken to Japan by the puzzle printing corporation Nikoli. It introduced the game in its paper Monthly Nikoli sometime in April 1984. Nikoli president Maki Kaji gave it the name Sudoku, a name that the company holds trademark rights over; other Japanese publications which featured the puzzle have to settle for different names.

In 1989, Sudoku Puzzles entered the video games arena when it was published as DigitHunt on the Commodore 64. It was introduced by Loadstar/Softdisk Publishing. Ever since then, other computerized versions of the Sudoku Puzzles have been developed. 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.
