ABSTRACT:
A full size conventional Backgammon Board is provided, embodying means for a central portion thereof movable with respect to the Board, said means embodying a plurality of windows. In normal position the windows appear closed. After a proposed move is made the central means are slid so that the windows uncover a diagrammed answer to the propriety of the move. Upon lifting the central portion off the Board, a textual explanation of the answer to the move becomes visible on certain instruction cards containing learning matter.
