Sudoku Puzzles: An Interesting Brain Teaser

Solving Sudoku Puzzles are brain teasers that have also been called wordless crossword puzzles. Sudoku Puzzles are usually solved through creativeness and have been building a huge impact all across the world.

Also known 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 every cell which is found on a 9 x 9 grid that is subdivided into 3 x 3 sub grids or regions. Many digits are often given in a few cells. These are referred as givens. Ideally, at the end of the game, each row, column, and region should have only one instance of every numeral from 1 through 9. Patience and logic are two characters needed in order to end the game.

Number puzzles quite akin to the Sudoku Puzzles have previously been in existence and have found publication in many 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 just double-digit figures rather than the present 1-9. Another French newspaper, La France, created a puzzle in 1895 that utilized the numbers 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 daily features in many other newspapers, including L'Echo de Paris for about a decade, but it unfortunately disappeared with the arrival of the First World War.

Howard Garns, a 74-year-old retired architect 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 periodical Dell Pencil Puzzles and Word Games under the title Number Place. Garns' design was presumably inspired by the Latin square invention of Leonhard Euler, with a few changes, basically, with the addition of a regional restriction and the presentation of the game as a brainteaser, giving 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 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 magazines 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 launched by Loadstar/Softdisk Publishing. 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.
