Modified Chess Game

Abstract

An extended chess game comprising a board divided into a first area, the Spirit World, consisting of all squares on the border forming a square ring and a second area, the Cardinal World, consisting of all the squares enclosed by the Spirit World. The pieces comprise conventional chess pieces, non-conventional chess pieces that are present at the beginning of the game and non-conventional chess pieces that are not present on the board at the beginning of the game. The rules allow the pieces to change color, to move from the Spirit World to the Cardinal World and vice versa, to kill members pieces of their own color, to move in lock step, two at the time, to come back to life after they have been killed by an opponent's piece, to be cloned, and to acquire abilities of belonging to pieces that have been killed.
