Diimuball is played by one player on field per team. The team is composed of four players one in the field and three are substitutes. The game is forty minutes in length, divided in two equal halves of twenty minutes each. The player is a goal keeper as well as a field player who plays all the roles in the sport.

A goal is scored when the whole of the ball passes over the goal line, between the goalposts and under the crossbar, provided that no offence has been committed by the team scoring the goal. The team scoring the greater number of goals is the winner and takes 5 points.

If both teams score no goals or an equal number of goals the match is drawn and each team takes 2 points. But when competition rules require a winning team after a drawn match, the only permitted procedures to determine the winning teams are, two equal periods of extra time not exceeding 5 minutes each, Kicks from the penalty mark. A combination of the above procedures may be used.
