Abstract

Abstract An educational game in which cards marked with data are to be matched with each other, employing two sets of cards. One set of cards are individually mounted in hollow cylinders, each with an open face window opening through which the marking on the mounted card is visible, and the other set of cards are individually mounted in a slotted rectangular shaped frame, each also similarly fitted with a window opening. The cylinders and frames each fitted with a card are initially mounted in recesses in a rotatable holder, which conceal their window openings and from which they are drawn. The cylinders and frames are each fabricated with a magnetic attractable material so that they may be individually removed from the holder by use of a pick fitted with a magnetic tip.
