Educational toy essentially characterized by having a base of substantially semicircular shape whose top is flat and arises from it a frustoconical pivot that ends at the top with a spherical top with the pivot intended to accommodate up to six rings whose overall diameter is less the greater of which the five larger ones that occupy the lower positions have the same size of the central hole while the upper ring that is the smallest also has a smaller central hole so that it passes with some difficulty through the spherical top of the pivot so that when the toy is overturned, the rings do not come out if there is not a slight pressure to remove the top one.
