We chose a parallel circuit as the brightness of the light bulbs will be the same. The arrows indicate the flow of the current. Currently, in our diagram, the bulbs are all light up as the circuits are closed. The Teams' Light bulb lights up as they close the circuit by pressing the switch, then the Emcee can see which bulb lights first. The emcee has a light bulb so that he/she can be seen by the teams and the audience can compare the light bulbs of the teams to the emcee's. There is a another switch at the top left of the diagram to switch off all the bulbs when not in use.
