Cee-lo is a Chinese dice game whose name comes from the numbers four-five-six (sì-wǔ-liù), the best roll. It was described in 1893 among Chinese workers in the United States and later became a well-known street game in New York, especially in the 1970s and 80s. There are many variants, and it is often played for money – here you only play for points and wins. Some trace it back to the European game passe-dix.
