A Brain Teaser Called Sudoku Puzzles
Solving Sudoku Puzzles are brain teasers that have also been known as wordless crossword puzzles. Sudoku Puzzles are frequently solved through lateral thinking and have been building a large impact all across the world.
Even known as Number Place, Sudoku puzzles are actually logic-based placement 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 numbers are often given in some cells. These are referred as givens. Ideally, at the conclusion of the game, each row, column, and region must have only one instance of each number from 1 through 9. Patience and logic are two qualities needed so as to finish the game.
Number puzzles very much akin to the Sudoku Puzzles have already 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 utilized just double-digit numbers rather than the current 1-9. One more French newspaper, La France, created a puzzle in 1895 that utilized the figures 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 puzzles were daily features in several other newspapers, as well as L'Echo de Paris for about a decade, but it unfortunately disappeared with the advent of the First World War.

Howard Garns, a 74-year-old retired architect and freelance puzzle constructor, was considered the designer of the contemporary Sudoku Puzzles. His design was first published in 1979 in New York by Dell, through its journal Dell Pencil Puzzles and Word Games under the heading Number Place. Garns' design was most likely motivated by the Latin square invention of Leonhard Euler, with a few modifications, basically, 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 out the empty cells.
