It's kind of soccer...but it's more of an assault on the referee! Click and drag to aim the ball and release to pass to a teammate or strike the ref. If you hit the referee, it's a point for you - but if you miss and the ball goes out, it's a point for him. The first to 5 wins!
Play now and knock out the referee!
