Maka dai dai shogi

Maka dai dai shōgi (摩訶大大将棋 or 摩𩹄大大象戯 'ultra-huge chess') is a large board variant of shogi (Japanese chess). The game dates back to the 15th century and is based on dai dai shogi and the earlier dai shogi. The three Edo-era sources are not congruent in their descriptions of the pieces not found in smaller games. Apart from its size and number of pieces, the major difference from these smaller games is the "promotion by capture" rule. A more compact modern proposal for the game is called hishigata shogi.
