Counting from 2000, computer lottery has only a short history of two years in my country (mainland), and 20 years ago in 1982, American lottery expert Ms. Gail Howard first proposed The theory of "balanced number selection" and the strategy of "smart combination" triggered a revolution in the history of lottery. Since then, the gambling industry that is popular in the United States and European countries has changed from a simple game of "luck" to an intellectual competition that emphasizes skills. A set of lottery number selection strategies created and continuously updated by Gale has so far created 65 million-dollar jackpot winners, with a total prize of $97 million. This record is included in the Guinness Book of World Records and is known as the "midwife to the lottery millionaire". She still holds a record - under her guidance, three American lottery players won million-dollar jackpots on the same day. Previously, Gail Howard was a very successful stockbroker and futures trader. Her ability to turn ordinary lottery players into millionaires has led to her appearing on hundreds of radio and television stations, including Today and Good Morning America.
