Abstract
Abstract Apparatus reproducing a game, such as GO, which employs two kinds of stones or pieces. The apparatus includes an information pick-up, a plurality of display elements and controllers for operating the display elements. The information pick-up picks up desired information from a recording medium which provides information as to the positions of the respective stones placed sucessively by each opponent in an alternate order. The display elements designate each of the two kinds of stones and the fact that no stone is placed. The controllers are actuated in dependence on the output of the information pick-up.
