100 Balls Challenge is a relatively new Windows Phone game that isn't very complicated but will test your timing skills.
You are given a supply of 100 balls in a hopper and have to fill passing cups with those balls. The cups will then dump the balls back into the hopper for re-distribution. The goal, keep your balls and cups in play as long as possible.
Graphics are minimal, game play challenging and overall 100 Balls Challenge comes across as a fun time waster for your Windows Phone gaming library. I don't know if it would hold up to marathon gaming sessions, but short bits it should do nicely.
