Head to Head, which is available on www.Flash-games.net, is a challenging sport game. You and your colleague are very boring in your office, so you have a good idea that you play ball with your heads. All you have to is to move left and right with your mouse. You can choose any team as you like, England, Russia, Denmark, and Sweden and so on. Head the ball back and forth to the guy at the top for points. Only consecutive headers build up your score. Go ahead and try to score high points. Good luck!
