Computer toy to demonstrate logical relationships, e.g. to a child, having a personal computer-like housing, a display system displaying a plurality of first and second type symbols, each first type symbol being logically related to one among the second type symbols to form a related pair, a plurality of housing positions corresponding to the symbols and each adjacent a respective symbol, an input system to select a particular housing position and indicate its selection and its adjacent symbol as one of a pair to be formed by such selecting, a circuit detecting whether a first and a second type symbol have been properly paired to form a related pair upon selecting by the input system a housing position adjacent a first type symbol and a housing position adjacent a second type symbol, and an output system issuing one signal if a related pair has been formed and a different signal if not so formed, and particularly such that where the circuit detects that all the related pairs have been successfully formed from among the symbols, the output system issues a still different third signal. The toy has an indicator indicating a program mode correlating the circuit and display system for forming the related pairs, and a control to program the circuit to that mode.
