Unlimited balls. All levels unlocked.
In order to play penalty simply click on the football and drag in the direction you want to kick it and as hard as you want too in order to score a goal but don't be too powerful otherwise you'll miss the target.
The aim is to score the penalty in order to progress through the many challenging levels. It wont all be plain sailing though, on the way you'll find unusual obstacles including clowns and cupid to keep you on your toes and test your penalty taking skills. So watch out and shoot your way to glory!
