From 2018 to 2019，China’s lottery market experienced a roller coaster-like sales rise and fall. The overall rise and fall in sales was mainly caused by the sales changes of guessing lottery tickets and high-frequency quick-open lottery games. Combining the theory of government regulation and the government regulation policies of several types of lotteries in 2019，the relationship between lottery types，addiction and regulatory policies are discussed. For the stable and healthy development of my country’s lottery market，regulatory authorities need to carefully conduct prior and in-process supervision. Lottery agencies must optimize the product structure of lottery games，strengthen responsible lottery management，and the lottery industry must properly handle the transformation of existing lottery business models.
