Abstract
Five related strategy type board games which are variations of conventional chess. Two are generic versions which can be played on sixteen square to sixty-four square boards using only simplex pieces: rooks, bishops, and knights; and duplex pieces: princess, crown-prince, and archbishop which are composites of two different simplex components and possess their dual powers. A third version played on a one hundred square board, includes three pairs of simplex playing pieces: rooks, bishops, and knights; three different types of duplex playing pieces: archbishop, crown-prince and queen, are all composites of two different simplex components; plus a king and ten pawns. Pawns have increased powers of movement, cannot be converted to queens, but can liberate captured pieces and possibly be knighted in the process. The crown-prince may succeed to the throne when the king has been annihilated, permitting the contest to continue. The fourth and fifth versions are played on one hundred forty-four square boards using four different types of simplex pieces: rooks, bishops, knights, and bowmen; six different composite duplex pieces having dual options: princess, duke, marquess, earl, viscount, and baron; four different composite triplex pieces having triple options: queen-II, crown-prince-II, counsellor and archbishop-II; twelve pawns; king-II, and court-jester that can exchange places with other pieces including king-II. All five versions can be played on a color-coded multi-perimeter gameboard comprised of six concentric square playing surfaces with marginal indicia.
