Zonk is an underground dice game played since the 1970s, often by university students, which is sometimes associated with drug culture, specifically marijuana use, a parallel to drinking games. Game play uses 6 dice, consisting of 3 pairs of white, red, and green dice, and involves 2-6 players. The goal of the game is to accumulate more points than the other players, and if played as a marijuana related game, to earn "bong hits".
One possible origin for the game says Zonk was created in 1978, in a freshman dormitory at an upstate New York university. A set of "official" handwritten rules were distributed in 1983.
