Abstract: Black Hole Chess is a game of tactics and strategy, played on a special board, which is larger than that of conventional chess and having vertical and horizontal grid lines as opposed to columns of alternating colored squares as in conventional chess. There are seventeen pieces representing futuristic, space-age figures on each of two opposing sides. Two players, one for each side, face each other across the board. The object of the game is to maneuver one's pieces, according to prescribed rules, in such a way as to put the opponent's President in a condition of "checkmate" or "stalemate," that is, a situation in which he is threatened with capture and cannot move out of vulnerability in any direction.

Abstract: A game set comprises a board having indicia which relate to indicia on individual pieces which can be associated with the board. There is an interconnection between the pieces and electrical impulse means also associated with the board whereby if the pieces are placed in incorrect positions on the board the impulse means will respond, such as by actuating a buzzer. The connections are identical, but the pieces need not be.
