If you opt for only the machine you basically just sit back and watch while it does all the work for you, keeping track of which numbers are called and marking them on the screen automatically.
There is also a small bar on the right side of stage, which also has lights on it. On either side of the room, a giant screen showing which numbers have been called hangs from the ceiling, and a large disco ball spins over a dance floor at the foot of the stage. Situated on a stage at the front of the room, a caller sits behind a podium with light-up panels, flanked on one side by a DJ named Orlando and on the other by another person with a light-up podium whose function is not as clear, but presumably equally important.
