Elimination is also valid if brought about by an external force (such as a non-participant or a previously eliminated participant). For example, during the 1999 Rumble match, both Vince McMahon and Steve Austin left the ring, only to return later in the match. A wrestler who exits the ring without going over the top rope is not eliminated from the contest. If they have any other part of the body touching they are out as well. The match has no stipulations or rules other than that elimination must occur by a participant being placed over the top rope and both feet touching the floor. These peculiarities are credited to Pat Patterson. The match begins with the two participants who have drawn entry numbers one and two, with the remaining competitors entering the ring at regular timed intervals, either ninety seconds or two minutes, according to their entry number. This usually takes place before the Rumble begins. The Royal Rumble differs from a battle royal as the contestants do not enter the ring at the same time but instead are assigned entry numbers, usually via lottery, although they can win guaranteed, desirable spots via a number of other means, the most common being winning a match. At the 2011 Royal Rumble, for the first time 40 entrants were scheduled to compete the most in the history of the event. The inaugural match in 1988 featured 20 entrants. The winner of the event is the last participant remaining after all others have been eliminated. The match is based on the traditional battle royal match, in which 30 participants, aim at eliminating their competitors by tossing them over the top rope, with both feet touching the floor.
