A upside-down soccer game? Yes, it is. And it seems quite strange? Different from the other soccer game in physics play, there are only 4 players in the game. Players of both sides flipping on the yard. You could get a score just through kicking the ball into the gate, no matter how you kick by hand, mouth or head.
Be attention, it is a funny game, come and invite your friends to join the game asap.
