Chungi

Chungi(Nepali:चुंगी) is a traditional game played by children of Nepal and North Eastern India. 
The set-up of the game is similar to Hacky Sack. The game is played with a ball made by tying a group of rubber bands at the middle. 
Gameplay.
The rules of the game varies by the region where it is played. The traditional way to play the Chungi is by counting the number of times the ball can be hit by feet without dropping in the ground. Using both feet is allowed, but using any other body parts is not allowed. Generally, a target count is decided for the game to get over. At the end of counting, a back kick is done to the ball to hit it as far as possible. The ball should be far enough than the previously decided distance, the distance being measured by the feet of the player. If s/he cannot hit, other player get the chance to continue their part. Other method of playing the game is by passing the ball to other players by foot without letting it drop in the ground. 
Impact.
It is considered that Chungi is one of the reason to reduce popularity of Dandi Biyo, another traditional Nepalese game. 
The game of Chungi has also been used to teach children mathematics and other concepts in school.
