Ten comedians stay in a living-room style studio with hidden cameras for a few hours (usually six) During this time, they must try to make their opponents laugh in any way and by any means, while not reacting at their opponents’ attempts to make them break. At the first laugh, the competitor is cautioned (yellow carded), while a second eliminates the player from the game (red carded) Eliminated players join the host in the observation room, but may return as an external challenger to the remaining contestants.
