Abstract: A wireless lockout apparatus, a system and a method for using the same are provided for receiving wireless signals from individual transmitters. When a first signal has a code that matches a reference code in a decoder, the decoder locks out subsequent signals and only allows the first transmitted signal to be routed through the processor. The processor determines which contestant sent the signal by interpreting the coded signal and indicates audibly and/or visually to which contestant the signal corresponded. A master transmitter has a bonus button and a reset button. The bonus button indicates a bonus question condition in a particular game. The reset button unlocks the decoder and allows the system to receive contestants' signals transmitted wirelessly.
