The cast receive directions from the Spielleiter (game master) on their headphones, and have to follow the cues, e.g. "Cordula: Tell the others you're pregnant!".
The main cast have included Cordula Stratmann, Annette Frier, Martin "Maddin" Schneider, Michael Kessler and Ralf Schmitz.
In September 2005 she took over the task of the game master, after Georg Uecker left or had to leave the show for unknown reasons.
So that the show could reasonably be continued without Cordula Stratmann, who was on maternity leave and was therefore not available for some episodes, they created a pub next door, the Schillereck (Schiller corner).
The rights have been sold as well to France, Italy, Spain, Belgium, the Netherlands, Finland, Estonia,[2] Russia, Romania, Hungary, Turkey, Czech Republic, Israel and Bulgaria.
In South Africa the show is produced and aired by Afrikaans channel kykNet under the title Proesstraat.
