"A ball is bouncing inside the circle and you have to make sure it keeps doing so! Keep in mind that the ball will only bounce if it hits the part of the circle with the same color. The circle has 4 parts with 4 different colors and the color of the ball will also randomly change to one of these colors. So you have to be quick to rotate the circle and prevent the ball from touching the side with a different color."
