Take a small ball as high as possible. Tap the screen to jump from one step onto another. Pick up various bonuses on your way. The idea of this simple but engrossing game is to go up steep stairs as high as possible. Be attentive and don't let the ball fall into the abyss. The stairs may complete unexpected turns so your task is not that easy as it might seem.Pick up crystals to buy new balls. Compatibility : Android 2.3 and up.
