Abstract: This invention describes a game of inverse chess, with a pre-identified start position, and end position and arbitered moves chosen amongst a set of possible moves, played between two opponents on a chess board. This differs from normal chess in that it is played backwards in time where the objective is to reconstruct the pre-identified start position, from the pre-identified end position. While the pieces used in the game are essentially the same as that of regular chess, the moves they make are reversed. Since the state-space of this game is much larger in the potential moves, an arbiter is used to validate possible moves that one player might choose to make. Using either a regular or modified chess board, the pieces on the board move backwards. Three such moves are described in the I-castle, spawn and I-check moves. A variant of the game is the two-knight game wherein two knights play each other and the piece reaching the pre-identified start position, win.
