The Glass House (US)

Each team tries to solve a large wall puzzle by using knowledge about fellow contestants in the series premiere of this reality-competition show featuring 14 contestants living in a house rigged with cameras.

The first elimination occurs. Then, the contestants go to great heights in a game called "Ruffle Your Tail Feathers," which requires coordination.

After the second elimination of the remaining contestants, the players compete in a physical game of "Triple Threat," where two opposing teams compete against each other as they perform tasks of America's choice.

A third player leaves the game, and those remaining play "Lab-A-Doodle," a game requiring balance, control and teamwork.

A fourth player exits. Later, the contestants play "Choose Your Weapon," a game that involves breaking glass windmills.

Following the elimination, the contestants play a game in which each team has to solve picture puzzles; two contestants find themselves in limbo.

Following the elimination, the teams face a competition where they must get balls into designated pockets.

Eliminated contestants return to the house; teams compete in a game of skill and endurance; a contestant is permanently eliminated.

The players rappel down a building past apartments decorated to fit eliminated contestants and answer questions about the apartment's contents.

Following the elimination, the four remaining players compete as individuals in a puzzle challenge; the challenge winner and two players chosen by viewers compete for the grand prize.
