Sudoku Puzzles: An Excellent Brain Teaser
Solving Sudoku Puzzles are brain teasers which have also been identified as wordless crossword puzzles. Sudoku Puzzles are usually solved through inventiveness and have been building a huge impact all across the world.
Also called as Number Place, Sudoku puzzles are indeed logic-based assignment brainteasers. The aim 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 digits are often given in some cells. These are known as givens. Ideally, at the end of the game, each row, column, and region have to contain only one instance of each number from 1 through 9. Patience and common sense are two characters desirable so as to end the game.
Number puzzles quite similar to the Sudoku Puzzles have previously been in existence and have found publication in several magazines 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 only double-digit figures instead of the current 1-9. Another French newspaper, La France, established a puzzle in 1895 which used the figures 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 daily features in numerous other newspapers, and also L'Echo de Paris for about a decade, but it unfortunately disappeared with the beginning of the First World War.

Howard Garns, a 74-year-old retired builder and freelance puzzle constructor, was considered the creator of the contemporary 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 title Number Place. Garns' design was presumably motivated by the Latin square creation of Leonhard Euler, with some modifications, mostly, 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 publishing company Nikoli. It initiated 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 tradename rights over; other Japanese newspapers which featured the puzzle have to settle for other names.

Since then, other computerized versions of the Sudoku Puzzles have been established.
