Len choa

Len choa is a two-player abstract strategy game from southern Thailand (formerly called Siam), first documented by Captain James Low in 1839.

It is unknown how old the game is, and it is only known from the periodical Asiatic Researches; or, Transactions of the Society, Instituted in Bengal, For Inquiring into The History, The Antiquities, The Arts and Sciences, and Literature of Asian, Second Part of the Twentieth Volume and specifically in chapter X On Siamese Literature (1839) in which Low authored.

[1] It is very similar to a game played in Sri Lanka called Hat diviyan keliya.

Leopards win if they surround and immobilize the one tiger.

The board used is a triangle dissected by two lines across its breadth, and one line across its length through its central axis.
