Nevada outlines casino gambling. By the end of 1910 virtually all gambling is outlawed in the United States. The 18th Amendment, prohibition, is submitted by the Congress to the states. Prohibition becomes law in 1919 when ratified by the 36th state, Nevada. Nevada re-legalizes casinos, becoming the only state with legal casino gambling.
Prohibition is repealed.
Almost all states change their laws to allow parimutuel betting on horses and low stakes charity gambling. New Hampshire rediscovers the state lottery. The first drawing is held in 1964, the first legal lottery in this century. Players fill out long forms for drawings held only twice a year. First casino opens in Atlantic City, making New Jersey the second state with casinos.
