Among Tibetan children the most popular traditional games are takchom (acrobatic skipping), with singing, and tepe, which is similar to the American game hacky-sack. A tepe is usually made either out of a small slab of metal with a hole in which feathers are fixed, or sand wrapped in a piece of cloth. The objective of the game is to keep the tepe in the air for as long as possible using only the inside of the foot and ankle. A favorite adult pastime among Tibetan refugees is a dice game called sho. It is played by two or more people and consists of two dice, cowrie shells, and a set number of markers for the respective players. The players roll the dice by slamming down a cup with the dice inside while voicing loud, often poetic, exclamations.
Tibetan refugees also have adopted some of the games of their host countries, such as soccer, basketball, volleyball, and cricket. Archery is common in some areas of Tibet; archery contests are held in a few refugee settlements in India.
