The general essence of the game is as follows. There is a field of light green cells framed by dark green cells. From dark-green cells from time to time balls of blue and pink appear, which randomly roll around the main field. You cannot directly control them, but you can use the mouse clicks on the cells to direct their movement in one direction or another (you can put the cursor in a block that does not have another ball, and choose from the positions “/” and “”, in one of them and the ball will roll further).
