A marble run apparatus kit includes a plurality of physically interconnectable marble run modules, each module configured to retain a marble and guide the travel of the marble through the module. The plurality of marble run modules includes at least a first controllable module. The first controllable module includes a baffle, an actuator, and a wireless receiver. The baffle is disposed in the module, and has a first position and a second position. The baffle is configured to direct the marble within the module in different directions based on whether the baffle is in the first position or the second position. The actuator is supported on the module, and receives a first control signal. The actuator changes the position of the baffle responsive to receiving the first control signal. The wireless receiver provides the first control signal to the actuator upon receiving a first wireless control signal.
