1. A videogame comprising:
- a television receivera circuit for generating one or more movable light spot symbols on a line scanned screen of the television receiver;
an oscillator for generating horizontal synchronizing signals;
an oscillator for generating vertical synchronizing signals;
switching means for bright illumination and scanning of a predetermined intersection of horizontal and vertical sawtooth waveforms and the intersection being synchronized for generating a time proportional pulse;
a target detector directable to the moving light spot symbol;
an optical sensor incorporated in the target detector for receiving light energy emitted from the light spot on the screen;
a trigger arm attached to the target detector for controlling an electrical switch;
an output stage comprising an emitter attached to the target detector and connected to the electrical switch and to the optical sensor for emitting unmodulated signals for a direction missing shot and modulated signals for a hit and a wireless transmission means for sending the signals from the emitter;
an input stage for receiving signals sent by the output stage;
an amplification stage for amplifying the signals coming from the input stage;
a pulse converter stage connected to the amplification stage for generating a pulse of a first duration for an incoming modulated signal and of a second duration different from the first duration for an incoming unmodulated signal;
a coincidence gate for receiving the pulses;
a summation circuit receiving the output signals of the coincidence gate and synchronizing them with the synchronizing and output signals of additional coincidence gates; and
a counting and display stage connected to the television receiver for counting the shots when the trigger arm is actuated and for counting the hits when there is a coincidence in time between the actuation of the trigger arm and the entering of light energy on the optical sensor coming from the light spot on the screen and for displaying the results thereof on said television receiver.

Abstract
A target videogame employing a screen with a moving light spot symbol and a mechanically disjoint target detector. Signals generated by light received in the target detector and by discharging a trigger attached to the target detector are transmitted by wireless communication to the circuits providing for the screen display.
