Scram Ball is an interesting arcade game on www.flash-games.net for free. The goal for you is to send the ball to the shining hole. Of course you will encounter many locks and try to get the keys first to unlock them. Just be careful about the black holes. If your ball touches them, they will fall down and you will die because they do not lead the right answer. The score you obtain will be shown after the whole game is over, depending on how quickly you complete the task and how few mistakes you make. Good luck!
