In the gaming space, every second game strives to test your reflexes and Ball Stair Jump is one of them. The yellow little ball must climb the ladder to reach the finish step. While pressing the ball, you will make it bounce to the next bar. If it has sides on the left and right, you can not worry and take a break while the ball is dangling back and forth. But it may also be that on one side, or maybe on both sides, there will be no railing and then the ball will fall. You have to be very fast to get the ball to jump up instead of rolling left or right in Ball Stair Jump.
