About Sudoku

Sudoku is a game that calls on the player to employ their dexterity and logic in the enjoyable effort of completing this numerical puzzle. A concept known as a Latin square was properly the primary foundation for the development of the Sudoku puzzle. A Latin square was a phenomenon invented by the Swiss mathematician named Leonhard Euler, the square called on numbers to be arranged in a specific way so that the number only appeared once in each row/column. Moving forward two hundred years an American architect has been credited on developing the modern day Sudoku. Upon its invention Sudoku was not the worldwide phenomenon it is today. Its widespread renown occurred when Wayne Gould came across it in a Japanese publication, he subsequently started to create his own and ultimately got it published in the British newspaper; the times under the name Su doku. After this lone publication the puzzle subsequently gained a worldwide following which is forever expanding even to this present day.

How to play Sudoku

1. Starting the puzzle you will be greeted with a grid which is typically 9×9 in size this includes nine squares that are each 3 ×3 in size. Within this gird it will be predominantly blank though in accordance to the level of the puzzle (easy, medium, hard etc.) there will be a scattering of numbers throughout the grid these are known as givens.

2. It is the puzzle solvers task to fill in the blank squares with the valid numbers. What I mean by valid is that there should not be a repeat in number in a single row, square or column.

3. The puzzle is deemed complete when all the spaces have been filled with numbers and subsequently each row, column and square displays the numbers one through to nine.

Sudoku Varients

There is quite a number of cases where the traditional game of Sudoku has been tweaked a little to resemble a similar but different puzzle. I will detail a few of these below.
