As a result, "Twenty-One" became not only rigged, but almost completely choreographed as well. Contestants were cast almost as if they were actors, and in fact were active and (usually) willing partners in the deception. They were given instructions as to how to dress, what to say to the host and when, which questions to answer correctly or miss, and even when to mop their brows. The producers could shut off the air conditioning to either booth in order to make the contestants sweat more, making them appear to be under great stress.
