Multi-colored sand has become in demand and in the Sand Sorting Challenge game you will sort and pack it in a box. The supplier delivered several types of sand of different colors, but in transparent containers it lies in layers. Your task is to separate the layers so that the bottle contains sand of a uniform color. During sorting, you can pour a layer onto the same color or into an empty bottle and it will immediately go into the box of the corresponding color in the Sand Sorting Challenge. Gradually, the range of flowers will grow, as will the number of containers for them.
