when the cloud is white it means that is the end. when the cloud is red,blue,green or yellow you have to memorize the order of the cloud color. if you get the color of the cloud in the right order by hitting the drums in that order of color then you get 1 point. first you start with 3 colors then 4,5,6 and on. then it gets harder. and when you get the order right then the cloud says good job.(when you get it wrong the cloud says game over.)
