Sudoku Puzzles: The Best Brain Teaser

Solving Sudoku Puzzles are brain teasers that have also been identified as wordless crossword puzzles. Sudoku Puzzles are often solved through creativeness and have been creating a great impact all across the world.

Even referred as Number Place, Sudoku puzzles are actually logic-based assignment puzzles. The objective 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 numerals are frequently specified in a few cells. These are called as givens. Ideally, at the end of the game, each row, column, and region should hold only one instance of each number from 1 through 9. Endurance and judgment are two traits required so as to end the game.

Number puzzles quite akin to the Sudoku Puzzles have already been in existence and have found publication in several newspapers for over a century now. For example, 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 current 1-9. One more French newspaper, La France, established a brainteaser in 1895 that used the digits 1-9 but had no 3x3 sub-squares, but the solution does hold 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 fatefully vanished with the arrival of the First World War.

Howard Garns, a 74-year-old retired architect and freelance brainteaser constructor, was regarded as the creator of the current 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 heading Number Place. Garns' design was presumably encouraged by the Latin square invention of Leonhard Euler, with a little alterations, mostly, with the addition of a regional restriction and the appearance of the game as a brainteaser, providing a partially-complete grid and requiring the solver to fill in the empty cells.

Sudoku Puzzles were then taken to Japan by the puzzle publishing company 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 which the corporation 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 available as DigitHunt on the Commodore 64. It was initiated by Loadstar/Softdisk Publishing. Ever since then, other computerized versions of the Sudoku Puzzles have been developed. For instance, Yoshimitsu Kanai prepared 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.
