The aim of the game is to guide balls that fall from the top of the screen to target areas on-screen. However, you can do this using lines, scribbles, doodles or by placing physical objects anywhere in the physical play area in front of the iPad. The iPad stands in the Osmo holder and the clever Osmo gizmo can see what’s happening in the play area in front of the stand.
Use a pen and paper in the real-world play area. Any line you draw on the paper will appear on-screen and the balls will bounce of this (obeying the rules of physics in terms of angles etc – as far as we can tell). Physical objects (like the pen itself or even your hand) work in the same way, you will see them on screen and the balls will bounce off them.
As you progress through the levels there are more targets to reach with the balls and you are encourage to think of more and more creative ways to get there.
