Abstract: The present invention provides a system for synchronising a plurality of electronic gaming machines in electronic communication with each other. Each electronic gaming machine has a lighting device for displaying a light presentation on the electronic gaming machine and a lighting controller in electronic communication with the lighting device for controlling the display of the light presentation by the lighting device. The lighting controllers of the electronic gaming machines are in electronic communication with each other. A master lighting controller for controlling the lighting controllers transmits one or more signals to the lighting controllers so that the lighting devices of the electronic gaming machines (1) are synchronised to display the same light presentation simultaneously. A method is also provided.
