 Although in hazard the dice shooter may choose any number from five to nine to be his main number, de Marigny simplified the game such that the main number is always seven, which is the mathematically optimal choice.Both hazard and its simpler derivative were unfamiliar to and rejected by Americans of his social class, leading de Marigny to introduce his novelty to the local underclass.Fieldhands taught their friends and deckhands carried the new game up the Mississippi River and its tributaries.
