This set of sake cups is used to play a game in which each player rolls the die and drinks from the sake cup of the size shown on the face of the die. There are three sizes: ichigo (180 ml), gogo (900 ml), and issho (1,800 ml). These are paired with one of two different performances: a song or a dance. Depending on the face of the die, the player drinks from one of the three cups and performs either a song or a dance.
