A year ago it has been 30 years since sudoku was invented. Today sudoku is still one of the favorite puzzles for both young and old players. We can find it in many newspapers and magazines in the crossword section and for the time being there is no sign that the interest in sudoku will fade away.

History of Sudoku

Sudoku is a game invented by Howard Garns, an American who published it in 1979 under the name “Number Place”, at the age of 74. It took its current name after it reached Japan five years later. At first it was called “Suuji wa dokushin ni kagiru”, which freely translated means “numbers should appear once”. However, such a long name wasn’t very practical, so it was shortened to the current form – sudoku. To Poland sudoku arrived in 1996 as a supplement to the magazine Super Express. Eight years later began a real craze for sudoku around the world.

Sudoku rules

The puzzle consists of a board divided into 81 fields, 9 × 9. Our goal is to complete the boxes in such a way that in each row, column and in each of the 9 marked squares with an area of 3 × 3, there is one number from 1 to 9.
