The folk game involves groups, each with three or four members, fashioning what looks like a tray out of mud with prominent edges. A banger weighs about 30 kg and is about 50cm long and 30cm wide.

When a contestant throws one on a flat ground, it bursts with a bang and its edge breaks off from the body and stretches into a strip. The group whose bangers make the loudest noise and has the longest edge wins.

It is said that the festival has been organised since the 1st century CE, and the folk game has many legends around it.
