The Sudoku, also known as südoku, su-doku or su doku, is the fashionable Japanese logic puzzle. The history of sudoku is quite recent, although in the 19th century some French newspapers already proposed similar number puzzles, it was not until the 1970s that the sudoku we know today was developed in Japan. Since 2005 (when started) this logical game started to become popular internationally. The word sudoku in Japanese means (sü=number, doku=solo).

The rules are simple, it consists of a grid of 9x9 cells, divided into 9 quadrants of 3x3, which must be filled so that all rows, columns and quadrants (sets of 3x3 cells) have the numbers from 1 to 9 without any repetition. Obviously, the starting point is a board with some known positions. In general, the less initial numbers a sudoku has, the more complicated it is, but don't be fooled. The difficulty is not only determined by this variable. At we always try to make sure that the sudokus we generate are the most fun and with a perfectly adapted difficulty.

It is curious, but in 2012 it was mathematically demonstrated that for a sudoku to have a single solution it must have at least 17 initial positions. There are a multitude of scientific articles and publications that try to determine how many sudokus exist, how many options there are and how to solve them in the most efficient way.

Sudokus are combinatorial problems ideal for developing logical thinking. They help to keep the mind active and it is an excellent entertainment to maintain mental agility, especially with numbers. It also helps to keep your memory sharp as the more complicated sudokus require you to make guesses that force you to evaluate different options. Also if you are just starting to program Sudokus are a classic problem for programming students.

A great set of sudoku puzzles. The aim is to fill the grid so that each row, column and box contains the same numbers, usually one to nine. Simple! Of course not! Our easy ones might be, but the later ones are fiendishly difficult.

A sudoku puzzle is a 9x9 grid where some of the squares in the grid contain numbers. The rules are simple: every column can only contain the digits 1 to 9, every row can only contain the digits 1 to 9 and every 3x3 box can only contain the digits 1 to 9.
