Establish two goal lines at each end of the playing area with a circle drawn in the centre equally distance from them. The Spider (It) sits motionless in the circle. The flies move around the circle buzzing as they go they circle closer and closer. Suddenly the spider jumps up and chases them to either goal line. Those who are tagged join the spider and sit down in the circle to assist in tagging. The last fly caught wins and becomes the spider for a new game.
