A Scaffold match takes place on a scaffold above the ring. The two ways to win the match are to push the opponent off of the scaffold so that he/she hits the mat or to grab the flag from the opponent's home base of the scaffold and return it to one's own home base. Some variations include putting weapons or objects into the ring for when the opponent lands, for example card tables. The scaffold is not very wide, meaning wrestling moves are rarely done during these matches and stay a kick/punch affair.
Another variation, called a Scaffold Cage Match, is when the wrestlers beat each other until one is knocked off of the scaffold and into the ring. The ring is surrounded by a high steel cage and the only way to win is by pinfall.
Elevation X, another variation, has two scaffolds placed above the ring intersecting each other to form an "X". A Scaffold match has never occurred in WWE.
