Yahtzee was invented by a wealthy Canadian couple to play aboard their yacht. In 1956, the rights to the game were purchased by Edwin S. Lowe, who made a fortune selling Bingo games in the 1920's. To help spark sales of the difficult to describe game, Lowe started throwing Yahtzee parties, and soon the game took off, thanks to word of mouth. The Milton Bradley Company acquired Yahtzee in 1973. Today, more than 50 million Yahtzee games are sold annually. An estimated 100 million people play Yahtzee on a regular basis.
