Multi -colored balls will again become elements of an exciting puzzle for this time called Glass Ball Puzzle. Several glass flasks filled balls of different colors, and you are invited to distribute balls by color. There should be four balls of the same color in the flask. You have spare empty containers that can be used to solve the problem. Tear the balls there and fold the colors. If you transfer balls from one dishes to another, where there are already balls, you can only place if the top ball corresponds to the color of the ball that you are going to move to the Glass Ball Puzzle.
