As some would call it, soccer.  Whatever it is called it is played with the foot and a ball.  With 11 players on each side, a match is played on a large pitch.

I often played the game with the guys in the boarding department, I wasn't particularly good, but I guess I can pass.

It requires lots of team work, personal skills and fitness.  With 22 players on the pitch it'll be very hectic if a fight broke out, so player's discipline has to be very good as well!
