Abstract
A game module has a signal generator for generating a signal for supply to a playing piece when the playing piece is electrically coupled to the games module. The playing piece has a memory for storing data and is arranged to derive a power supply from the signal supplied by the game module by coupling to a user so as to complete an electrical path via the user back to the game module and to communicate data with the game module when power is thereby derived by the power deriving means from the signal provided by the game module.
