What are some "exotic" board games that are from around the world?

Last week, I learned how to play Mu Torere, one of the only games known to be indigenous to the Maori tribe of New Zealand.

This made me interested in other foreign board games. To be specific, I am looking for some games that are played by completely different cultures, other than in America/Europe.

Do you know a game played in the Amazonian rain forest? Great! Do you know a game that originated in Sub-Saharan Africa? Also great! Is the game thousands of years old? Perfect!
