Human Tetris

Human Tetris or Brain Wall

Brain Wall (脳カベ, Nōkabe^?) is a component of the Japanese gameshow series Tonneruzu no Minasan no Okage deshita (とんねるずのみなさんのおかげでした - Thanks everybody was TONNERUZU) that originated in Japan on the channel Fuji TV and first broadcast on 27 July 2006. As the show proliferated on video-sharing websites and the concept eventually adopted by several countries, it became popularly known to non-Japanese speakers as simply Human Tetris (or Hole in the Wall) for its involvement of the physical body and close resemblance to the rules of the Tetris game.Contestants are to wear hard hats and spandex and stand on the "Play Area". A Styrofoam wall consisting of openings originally shapes of Tetris blocks is revealed and moves towards the contestants. They have to make use of their wits in seconds to assume the position that will allow them to fit through the opening(s). Later episodes involved the use of more complicated shapes, such as words, gymnastic positions, and popular culture. Contestants usually have to twist and bend their bodies with agility and dexterity to fit through the hole in the wall.
