A TOY CONSTRUCTION SYSTEM

A toy construction system comprising a plurality of interactive construction elements each comprising coupling members configured for releasably interconnecting the interactive construction elements with each other, the plurality of interactive construction elements comprising a plurality of function construction elements, and one or more input construction elements, each input construction element comprising a wireless transmitter for transmitting a control signal to at least a subset of the function construction elements; each function construction element comprising: a function device adapted to perform a controllable function; a wireless receiver for receiving the wireless control signal; and a control circuit connected to the wireless receiver and to the function device and adapted to control the controllable function responsive to the received control signal; wherein each interactive construction element comprises a user-operable selector allowing a user to select one of a predetermined set of group identifiers; and a group indicator being configured to output, responsive to a selected group identifier, an indication indicative of the selected group identifier, and wherein each function construction element is configured to selectively control the function device of said function construction element responsive to a control signal received from an input construction element having a selected group identifier matching a selected group identifier of the function construction element.
