Abstract

A method and system for determining the presence and identity of a game piece placed at a sensing location by attaching one or more conductive rings at fixed concentric locations on the bottom of the game piece and sensing the presence or absence of the conductive rings by means of sensors that are insensitive to the rotational orientation of the game piece.
