Hole in the Wall (Philippine game show)

Brain Wall (脳カベ, Nōkabe^?) is a component of the Japanese game show Tonneruzu no Minasan no Okage deshita (とんねるずのみなさんのおかげで した, lit. "Thanks to the people from Tunnels." ["Tunnels" is a comedy pair.]) Video clips from the show proliferated on video-sharing websites and the concept was eventually adopted by several countries. It became popularly known to non-Japanese speakers and YouTube fans as simply Human Tetris or Hole in the Wall, named for its involvement of the physical body and a supposed close resemblance to the rules of the video game Tetris.

The rules of the game are the same, and how points are awarded vary from country to country.

The first component of the game involves a solo contestant, while later components involve groups of two people or more.

The production rights to the show outside Japan is owned by FremantleMedia and the program has been produced in 45 countries.
