When five cardsharps were lynched in Mississippi in 1835, the professional gamblers drove away from the south. The river towns became major attraction for professional gamblers, also known as cardsharps, who were hunting the travelers who used to carry large amounts of cash with them. The history of casino cruises and riverboat casinos in the United States goes back to the beginning of the 19th century when the Mississippi River was a major trade center for farmers and merchants. Nowadays, gambling on a riverboat casino is only one of the many options that the recreational gambler faces when he feels like shooting dice. Long before the online gambling revolution and even before the boost of tribal casinos, a casino cruise was the only legal way to gamble in the US besides Las Vegas and Atlantic City casinos.
