Sudoku Puzzles: An Interesting Brain Teaser



Solving Sudoku Puzzles are brain teasers which have even been identified as wordless crossword puzzles. Sudoku Puzzles are usually solved through inventiveness and have been building a large impact all across the world.

Also called as Number Place, Sudoku puzzles are in fact logic-based assignment brainteasers. The objective 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. Several digits are mostly given in certain cells. These are called as givens. Ideally, at the conclusion of the game, each row, column, and region have to have only one instance of each numeral from 1 through 9. Endurance and common sense are two traits desirable so as to end the game.

Number puzzles quite akin to the Sudoku Puzzles have already 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 utilized just double-digit figures rather than the current 1-9. Another French newspaper, La France, established a puzzle in 1895 which 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 daily features in several other newspapers, including L'Echo de Paris for about a decade, but it fatefully vanished with the beginning of the First World War.

Howard Garns, a 74-year-old retired builder and freelance puzzle constructor, was regarded as the inventor of the current 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 headline Number Place. Garns' design was most likely inspired by the Latin square discovery of Leonhard Euler, with some alterations, mainly, 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 empty cells.
