Which game is a chess variant, Ubongo or Ouk-Khmer?
Ouk-Khmer (Hill's version) Ouk-Khmer (also known as Cambodian Chess) is a chess variant which D. B. Pritchard claimed was played in Cambodia although its actual origins appear to be unknown. Pritchard gives the source as P. A. Hill. It combines elements of makruk and xiangqi. Similar to xiangqi, it is played on the intersections of an 8×8 monotone board (Instead of 8x9). Contrary to Pritchard's claim, the actual variety of chess played in Cambodia today, known as "Ok" or "Ouk Chatrang" is nearly identical to Makruk. The authenticity of the game described by Pritchard remains doubtful.
Game of the Three Kingdoms Game of the Three Kingdoms (Chinese: 三國棋 , "Sān-guó-qí" ; also called Sanguo Qi, Three Kingdoms Chess, or Three-Handed Xiangqi) is a three-player variant of the game xiangqi ("Chinese chess"). The game symbolizes the Three Kingdoms period war (221–264 AD) between the rival states Wei, Shu, and Wu, each vying for control of China after the fall of the Han Dynasty.
