It is hard to understand the aim of the game, what are the rules ?

The idea is to add or subtract the colors of the side orbs (the drawing on the floor tells you this), the result of which is shown in the central orb. In such a way that the color of the central orb and the computer screen are the same.
Then the rules would be to hit the orbs to make them change color so that the color of the central orb and the computer screen are the same.
I guess, but I'm not really sure.
