The source of questions is irrelevant, but, of course, questions must be unknown to players. Usually hosts of a tournament obtain a packet from a Club in another city. The packet is given to a moderator. Teams sit around separate tables. Each table is provided with a timer interruption button and a signal light.
Teams have one minute to discuss the question.
The game host must signal when 50 seconds have passed and 1 minute has passed. When a team wishes to answer the question, the captain must press the timer interruption button. The timer stops and the light signal on a team's table flashes. After that, the team must stop all discussions and answer in 20 seconds. The captain determines which player will answer.
