Tu Sac (Tứ Sắc - Four Colors) is a popular Vietnamese game played
with chess cards. The objective of the game is to organize a hand
of cards into a combination of valid Tu Sac sets of cards through a
process of melding new cards into the hand and discarding out trash
cards. It is known as Si Se Pai (which also means four colors) in
Chinese.
