Foosball Stat Tracker

Rough outline of a new foos app I am thinking of. Watch a game of foosball, and where ever the ball is, click / touch on that rod. The app should track stats for you (number of completions / number of attempts) and provide a count down timer for basic reffing purposes. The stats are formatted as follows: For 3 rods - there's only goals / attempts. For 5 rod there, goals / passes / attempts. For 2 rod its, goals / clears / attempts. Once the format is all figured out, i'll add some nice graphics to it (something like a top down view of a foosball table)
