This game was synthesized from a number of sources: description of the obscure Thai and Malay games of Mak-yek and Apit-sodok from Murray's A HISTORY OF BOARD GAMES OTHER THAN CHESS, Vuthy Tan's description of the game of Rek from his article "Cambodian Chess Games", the Japanese game of Hasami Shogi, the old Viking game of Hnefatafl, and a little bit of Checkers.
