The two wires act as a switch, opening and closing the circuit. There’s a second switch for selecting the mode you want. ,She uses a SPDT switch that is On-Off-On so you can select either setting, but still turn the game off. To make the circuit she puts the wire loop and maze after the battery pack, but before the mode switch.
