Abstract: An electronic game for finding which one of 12 signals is different than the other signals and whether it is larger or smaller in magnitude includes 12 single pole double throw center-off toggle switches. A circular shift register is initialized with a digital one state in only one cell and clocked for a random period of time while an INITIALIZE button is depressed. Each cell of the shift register feeds a different one of the switch wipers. First and second contacts of the switches are respectively fed to different OR gates which in turn feed a random inverting means whose outputs feed drive a meter for comparing the sums of signals on the first and second contacts.
