This is a family of push-your-luck dice games, said to have been invented in the 1930s, popularized in American college circles in the 1970s, and subsequently commercialized.
Games in the family are typically played with five or six dice. In a round, a player rolls the dice trying to roll certain faces and combinations. After each throw one or more dice must be "locked" and the player can then choose whether to roll again or to bank any accumulated points. Rolling and failing to lock a die means losing all points for the round.
The games distinguish themselves through procedural requirements, scoring goals and requirements, terminology, optional rules and so on.
