Sudoku

Sudoku is very entertaining logic puzzle. It became popular in the early 00's and since then is still a good game for all ages and skills. The objective is to fill a 9×9 grid with digits from 1 to 9 following some simple rules.

How to play

  • Select an empty cell and choose a number from 1 to 9 to fill it;
  • The objective is to fill all the cells following these three basic rules:
    • Don't repeat the numbers in the same row;
    • Don't repeat the numbers in the same column;
    • Don't repeat the numbers in the same subgrid (3x3 box);
