Gambling in China is officially illegal under Chinese law. In practice, however, Chinese people can participate in state-run lotteries and engage in legal gambling in the special administrative regions of Hong Kong and Macau, whose legal systems resemble those of European countries which formerly administered those regions (the United Kingdom and Portugal, respectively).
Gambling in Macau has been legal since the 1850s, when it was a Portuguese colony. The region has a history of gambling on traditional Chinese games. Gambling in Macau now primarily takes place in Western-style casinos; in 2007, Macau overtook the Las Vegas Strip in gaming revenues.
