The game symbolizes the Three Kingdoms period war (221–264) between the rival states Wei, Shu, and Wu, each vying for control of China after the fall of the Han dynasty.
[1] O. von Möllendorff reported on the game in [German] "Schachspiel der Chinesen" (English: "The Game of Chess of the Chinese") in the publication Mittheilungen der deutschen Gesellschaft für Natur- und Völkerkunde Ostasiens (English: "Journal of the German Society for Natural and Cultural Science of East Asia"), Leipzig, 1876.
Subsequent to Game of the Three Kingdoms, similar three-player xiangqi variants emerged utilizing half-boards but with different center-connecting geometries and corresponding rules.
The three kingdoms Wèi (魏), Shǔ (蜀), and Wú (吳) are represented by colors blue, red, and green, respectively.
In addition, each player controls two bannermen pieces: "flag" (旗 qí) for Wei/Blue, "fire" (火 huǒ ) for Shu/Red, and "wind" (風 fēng ) for Wu/Green.
