ABSTRACT:
An educational game arrangement in which a systematic set of games may be played on a plurality of interrelated templates or game boards. The games played on the boards are aimed at teaching statistical principles, for example, as applied to situations in chemistry, biology, physics and economy, for example. The boards are superimposed on each other within a holding arrangement, and may be easily selected for playing a particular game. The boards or templates are held in predetermined registered position with respect to each other in the holding unit, and a transparent covering plate is positioned over the stack of the game boards. The latter is provided with coordinate markings along their rims, and the selected game board is visible through the transparent cover. The cover has openings or recesses which are arranged to correspond to a coordinate grid formed by the coordinate markings on the templates or game boards. Marking elements in the form of balls, for example, are insertable in the recesses or openings in accordance with predetermined rules dependent on numbers resulting from a toss of dice.
