The present invention is a computerized game device or game playing method for use with objects such as balls and a generally planar surface. The game device may comprise at least two electromagnetic beam transmitters arranged to emit electromagnetic beams and at least two corresponding electromagnetic beam receivers generating signals. The game device further comprises a support for the transmitters and receivers having a surface shaped to rest stably against the planar surface, the support positioning each transmitter to emit its electromagnetic beam parallel to the other beams and parallel to the planar surface, the support positioning each receiver to receive one of the electromagnetic beams, and the support shaped to permit the objects to pass through the beams and to strike the planar surface without striking the support. The game device further comprises a game computer arranged to receive signals from the receivers and programmed to implement at least one game where performance is judged by analysis of the signals received from the receivers.
