When all the balls are mixed in one container, you need to make a little effort to sort them. By shifting the balls from flask to flask, you need to ensure that each contains elements of the same type. At first, the task may seem simple enough. What can be tricky is to group 2-3 kinds of elements. What if there are 5 or 10? Make every effort to achieve the goal and make the minimum number of movements. Complete all levels and show everything that you are capable of. Good luck!
