Sudoku Puzzles: The Best Brain Teaser
Solving Sudoku Puzzles are brain teasers that have even been identified as wordless crossword puzzles. Sudoku Puzzles are often solved through lateral thinking and have been creating a great impact all across the world.
Also called as Number Place, Sudoku puzzles are in fact logic-based assignment puzzles. The aim of the game is to enter a numerical digit from 1 through 9 in every cell that is found on a 9 x 9 grid that is subdivided into 3 x 3 sub grids or regions. Several numerals are often specified in a few cells. These are called as givens. Ideally, at the conclusion of the game, each row, column, and region have to contain only one instance of each number from 1 through 9. Persistence and judgment are two traits required in order to end the game.
Number puzzles very much similar to the Sudoku Puzzles have previously been in existence and have found publication in numerous newspapers for more than a century now. For illustration, Le Siecle, a daily newspaper based in France, featured, as early as 1892, a 9x9 grid with 3x3 sub-squares, but used just double-digit numbers rather than the present 1-9. One more French newspaper, La France, formed a brainteaser in 1895 which 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 daily features in many other newspapers, as well as L'Echo de Paris for about a decade, but it fatefully vanished with the advent of the First World War.

Howard Garns, a 74-year-old retired architect and freelance puzzle constructor, was considered the creator 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 presumably motivated by the Latin square invention of Leonhard Euler, with some changes, mostly, with the addition of a regional restriction and the appearance of the game as a brainteaser, giving a partially-complete grid and requiring the solver to fill in the blank cells.
Sudoku Puzzles were then taken to Japan by the puzzle publishing corporation 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 association holds tradename rights over; other Japanese magazines which featured the puzzle have to settle for alternative names.
In 1989, Sudoku Puzzles entered the video games arena when it was published as DigitHunt on the Commodore 64. It was launched by Loadstar/Softdisk Publishing. Ever since then, other computerized versions of the Sudoku Puzzles have been developed. For illustration, Yoshimitsu Kanai prepared numerous computerized puzzle generator of the game under the name Single Number for the Apple Macintosh in 1995 both in English and in Japanese version; for the Palm (PDA) in 1996; and for Mac OS X in 2005.
