Quiz App iPhone UI

I worked recently on this design for an iPhone game concept. The screen shows a possible looking for the running game. You will be playing against a friend and your target is to reveal all ±20 list-entries. In this case you should know the highest paid movie actors. It is a round-based game concept where each person has about one minute to answer. The first person who can't answer or answers wrong, loses.

Be sure to watch the actual pixels and the rendering also for additional details. Feel free to comment, I hope you like it :)
Thanks @KonstantinDatz for the iPhone rendering.
