I made EVOCHESS (EVOlutionary CHESS) one night when I couldn't sleep. Pieces can promote not once but twice.(Some pieces may only promote once). It also has got the drop-rule from shogi. I made up some of the pieces but some of them are from the chessvariant pages' piecencyclopedia or from shogivariants.


Evochess is played on a 12x12squares board
