In boomerang chess, one or more pieces have boomerang powers, which is the Ability to capture an opponent piece (which is at a target square, reachable by the striking piece in a regular chess game), and return back to the its starting square in the same move! In one variant, the range of the boomerang can be limited. For example, the boomerang range of the bishop maybe limited to 4 squares etc. Other chess variants like Xray chess, Pool chess, magnetic chess etc. are also proposed in this invention.
