Pongo

Pongo is a free experimental game available on mobile phones. The aim is to bounce a ball on a beam while trying to hit the white dot. If you succeed, the ball then moves to the location indicated by the pink dot.

When you manage to hit the white dot, you earn as many points as there are stars left. A star disappears each time the ball bounces next to the white dot. You can adjust the beam by sliding your finger vertically across the screen."
