Super-Circe: When captured, a piece is reborn on any free field on the chess board without causing self-check or selfmate. Possible is also removal of captured piece from the board. The Pawns (white, black, neutrals, half- neutrals) can be reborn on the first or eight row also. When reborn on the first row (for Black) or on the eight row (for White) the promotion is obligatory. When reborn on the first row (for White) or on the eight row (for Black) the Pawns are immovable.

Radial Leaper (RK): Is a unit which moves by jumping over another unit of opposite colour (called a hurdle) in the way that the geometrical distance between destination square and the hurdle square (in any direction) is the same than the distance between the RK square and the hurdle square. (Example: black RKd6 can move through white hurdle Kg1 to the destination square b4 because d6-g1 = g1-b4)

Empress (EM): Moves as R+S.

Camel (CA): (1,3) Leaper.
