Divide the players into two teams of equal number and name them Black and White. Draw two parallel lines one metre apart across the middle of the playing space-this is neutral territory. 10 to 12 metres away at either side, draw goal lines. The players line up beside the neutral zone. A disk, one side of which has been coloured black and the other white, is tossed up so that it falls in the neutral zone. If the blacks side comes up the blacks run back to their own goal line and the whites chases the black. All who are tagged join the white side.
