WINNING (SCORING A GOAL):
The bladder may not be kicked into an open goal. It may either be
carried into the goal by the bladder carrier, or passed to another
piece which has been successfully manoeuvred into the goal. The
first person to score wins the game. N.B. Own goals count, i.e.
if a player moves or passes the bladder into their own goal, they
have lost the game!
