Mark six lottery introduction:

Mark Six Lottery is the only legal lottery in Hong Kong and one of the few gambling permitted by the Hong Kong government.

In order to crack down on folk Chinese character gambling and prevent gambling funds from flowing to illegal groups such as triads, the Hong Kong government began to sell lottery tickets from 1975 to replace the original horse tickets. The Hong Kong Lotteries Board, a statutory body, is responsible for the lottery, and the Hong Kong Jockey Club accepts bets on behalf of the Hong Kong Jockey Club Lotteries Limited.
