Someone mixed the balls in the flasks! Put things in order, sort the balls into flasks so that there are balls of the same color in the flask. This is not as easy as it might seem. In addition to ordinary flasks, there are special, harmful flasks in which you need to put balls of one specific color, others will not work.
You will find many exciting levels, built from easy to difficult. A little logic, a little patience and order will be restored!
The control is simple - click on the flask from which you need to get the ball, and then on the flask, where to send this ball.
