The coachman comes from the word ngrusir which means "to order to go far in various ways, if in this game by flicking or flicking the opponent's mound far away". This type of coachman gundu game has existed since the Dutch colonial period, then since the 1950s, this game began to disappear. Players throw mounds as their gacoan in turns, the mound closer to the available hole must repel the opponent's mound. For opponents whose mounds have been driven far away, to insert their mounds into the hole, they must poke the mounds with their index fingers.
