As is the case every year since the event's beginning, the event's main event was the 30-man over-the-top-rope battle royal, also known as the Royal Rumble match. The match started with two wrestlers and a new one was added every 90 seconds. To eliminate an opposing wrestler he must be thrown over the top rope and have "both" his two feet hit the floor, this will continue until there is only one man left, who is named the winner. The winner received either a WWE Championship match or a World Heavyweight Championship match at WrestleMania XXVIII.
