An educational toy comprises means for randomly generating a sequence of lights and/or musical tones. A child's task is to imitate these lights and/or tones by pressing corresponding input buttons. In the event of a correct imitation a box 2 is unlocked to permit the child to gain access to a prize located therein. The number of notes and/or lights may be selected in advance to vary the degree of difficulty. <IMAGE>
