A Brief History of Yahtzee

The modern commercial game called Yahtzee was marketed by game entrepreneur Edwin S. Lowe in 1956. Historical accounts say the underlying game was developed as the “Yacht Game” by an anonymous Canadian couple in the 1950s, and Lowe acquired the rights, renamed it Yahtzee and brought it to market. The Strong National Museum of Play records the game as dating to 1956. citeturn0search0turn0search1

Yahtzee also belongs to a much older family of dice games, with predecessors including Yacht and other sequence dice games. citeturn0search12
