MEMORY FOR BALLOONS

There are several gray balls in front of you. By clicking on them sequentially, discover and open pairs of balls of the same color. If you click on a blue ball, for example, and then click on the blue one again, then these two blue ones will disappear from the field. Thus, it is necessary to clear the field of balls.

Just keep in mind that you need to open the same balls in a row, because if after opening the red ball, you open the green one next, the three red and green ones will turn gray again. This point is good to use to remember the location of balls of a certain color, so that later, opening the same one, click on the already found one.
