The idea behind the Royal Rumble match is credited to Pat Patterson. Before the match begins, the contestants draw spots in the Rumble. The match consists of thirty men, beginning with the two men who chose entry numbers one and two in the ring.At regular timed intervals, usually ninety seconds, one of the remaining 28 wrestlers enters the ring. Participants must eliminate all other opponents, and the winner of the event is the last wrestler remaining after all others have been eliminated. A wrestler is eliminated when leaving the ring over the top rope, with both feet touching the floor.
