What is Sudoku?

History

Sudoku, also known as südoku, su-doku or su doku, is the trendy Japanese logic-type puzzle. The history of sudoku is quite recent, despite the fact that in the 19th century some French newspapers already proposed similar number puzzles, it was not until the 70s when the sudoku we know today was developed in Japan. From 2005 (when printsudoku.com started) this logical game began to become popular internationally. The word sudoku in Japanese means (sü=number, doku=alone).

Sudoku rules and difficulty

The rules are simple, it consists of a 9x9 cell grid, divided into 9 3x3 quadrants, 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 you start from a board started with some known positions. In general, the fewer initial numbers a sudoku has, the more complicated it is, although don't be fooled. The difficulty is not only determined by this variable. At PrintSudoku.com we always try to make the sudokus we generate the most fun and with perfectly adapted difficulty.

Sudokus must have a unique solution to be correct.

Magic Sudoku

Magic Sudoku is a variant of traditional sudoku. It is characterized by adding the following restrictions to the original sudoku:
  • Each main diagonal also contains the numbers from 1 to 9 without repetition (like quadrants, rows and columns).
  • In each quadrant only one unique number appears.
  • There are colored cells, the numbers that are in these cells must have a value equal to or less than the number of colored cells in the quadrant in which they are located.

This Sudoku is more complicated, but also much more challenging and fun. Do you dare?
