public class Referee

extends java.rmi.server.UnicastRemoteObject

implements RefereeIntf

Referee is in charge of initialising the game and delivering the moves to each player. The Game class has a reference to the Referee and it calls it to place the player's next move. The Referee also has references to all of the Observers, which in turn have references to the respective Game classes on each MMC.
