The rules of each round are new every time, as the framework of the rounds is decided by the panellists. Due to the fact that the structure is continuously changing, essentially the format of the show is that it has no format.
Instead, each of the panellists creates and brings their own round to the show for the other panellists to play. Four comedians compete to see who gets to be champion.
