Dai Dai Shogi is a difficult game to learn and play, resembling a war game
more than a chess game. We created the Dragon and own the rights to it.
The other pieces are all royalty-free. All pieces and moves are the same
as in chess with the exception of the Dragon that moves like a queen in any
direction and in a straight line but limited to 3 squares, no jumping. The
rules remain the same. The board is designed to play standard chess as
well.
