Abstract
Abstract A game board for the playing of checkers, chess and the like has two removable and replaceable central rows of squares. Some of these squares carry different inscriptions forbidding the movement of the pieces thereon under the playing rules. The removable rows may be located upon panels, sheets, films or the like. Their number and location can be varied. Games can be varied to the greatest extent by the use of differently located movement forbidding squares.
