Rules of Sudoku are quite simple, but it’s not so easy to play it on difficult levels.
All you need is to enter the numbers from 1 to 9 into all free cells so that each number appears just once in each column, each row and each square (3 x 3 cells). The puzzle is considered solved if you’ve filled all free cells correctly.
Enjoy the game and good luck!
