PURPOSE: To allow playing pieces to be put in order when playing is over, by forming a frame on the periphery of a game board and installing a housing cover which can be installed and demounted at the place where the playing pieces are housed.

CONSTITUTION: On a game board, a frame 2 having an arbitrary height is installed in the state where a board surface is surrounded. Further, a housing cover 1 is allowed to be inserted by forming a gap between the frame 2 and the board surface. The housing cover 1 is made of the material having elasticity, and the left and right edges are formed so as to be inserted into the gap. The housing cover 1 has a lower part surface, in order to prevent the drop of playing pieces 3. Further, the housing cover 1 is made nearly transparent, in order to allow the playing pieces housed inside to be viewed. Accordingly, the playing pieces can easily be put in order when playing is over.
