"Dagelijkse Sudoku" Game

Dagelijkse Sudoku offers to solve a new Sudoku every day. Choose a date before the game and start the puzzle. The rules are simple: click on the empty squares and insert numbers from 1 to 9 so that they do not repeat in all vertical and horizontal rows of the large square. In the small squares the numbers must also occur once. At the beginning of the game be guided by the numbers that are already arranged. If a row or a small square has the same numbers, you will be pointed out the mistake. The game requires attention and concentration, but it is very entertaining.
