Anyone who prefers sudoku will be happy to see an interesting game Daily Kaodoku. Its rules are exactly the same as those that exist in Sudoku: elements of the vertical and horizontal should not be repeated. The difference lies in the elements that you will operate. These are not traditional numbers, but geometric figures: squares, circles and triangles. But their set is small, so it was decided to add faces: sad, funny and angry. Now you have plenty of opportunities to expose objects. Partially they are already placed on the field, it remains to add the missing ones.
