To play the right side use 1 to go up and 9 to go down and on the left side use the up arrow to go up and down arrow to go down.The first to get 10 points wins!
It is so,so very easy.i know it is hard playing both sides but,anyways hope you liked it!And if the ball turns and turns and turns,then i am sorry for that.i don't know why that ball turns!
