Sudoku – The Challenging Squares for Mind Play
Long before the evolution of technology, people engaged in simple yet powerful mind puzzles. Role playing games and paper pencil games were the two types of games that people used to keep them engaged and entertained. All that is needed for the paper pencil games is a paper and a pencil and hence the name. These games can be played by a single player or by multiple players.
Sudoku is one such paper pencil game which has become very popular for the single players. It is a puzzle where the numbers are placed based on logically thinking. This puzzle was originally based on the French puzzle Magic Squares. Many people misinterpret that Sudoku was developed in Japan due to its name, but it is an American invention from its very own New York. Leonard Euler invented ‘Latin Squares’ which was derived from Magic Squares that in turn led to the discovery of Sudoku. Wayne Gould, from Hong Kong, created the first puzzle which was published in the British newspaper in the name of Su Doku in 2004. New York published its first Sudoku puzzle in May 2005. Number place was the earliest Sudoku like puzzle which was published in the Dell magazine in 1979 by Howard Garns, a retired architect. Nikoli was the person who introduced Sudoku in Japan in the name “Suujiwadokushinnikagiru”. This phrase was shortened to form the word ‘Sudoku’ which meant the numbers should be single and unmarried. Nikoli created a rule and made the puzzles symmetrical.
Sudoku started evolving with different variants. 9x9 grids is the most common variant while there are 4x4, 5x5 and 12x12 grids as well. Nikoli created 25x25 grid puzzles. Sudoku-zilla which is a 100x100 grid puzzle was first published in the year 2010. The other variants of the modern Sudoku are Cross Sums Sudoku (clues are given in cryptic alphametics), Alphabetical Sudoku (also known as Wordoku), Hypersudoku (presence of overlapping squares).
Sudoku connects people around the world as there are no linguistic barriers in solving these puzzles. They are solely based on logically thinking and not mathematical skill.
The other popular paper pencil games that have evolved over time are Tic Tac Toe game (nine space game of Xs and Os), Knight tour games (moving the Knight on a 8x8 grid without repeating the squares) and Pictionary game (drawing to guess a word or phrase).
All you need is a paper and pencil to keep you challenged and entertained for hours!
