Police in China recently smashed another gambling ring that punted on virtual red packets on Tencent Holdings’ WeChat social media platform. Since last year, Shenzhen authorities have arrested 71 people for gambling activities on Tencent’s WeChat and QQ platforms, with the largest sum involved at more than 60 million yuan, according to the official Xinhua News Agency. Similar cases were also reported in Jiangsu, Hunan, Yunnan, Guizhou, Sichuan and Zhejiang provinces. Tencent declined to comment on the report. True dominance of China's big three internet companies revealed Handing out red packets, or hong bao , is a traditional way for celebration in China that has gone increasingly online in recent years. During the Lunar New Year period earlier this year, a total of 768 million WeChat users - or more than double the population of the US - sent or received hongbao via the platform, an increase of 10 percent from the year earlier, according to Tencent. Sina’s Weibo launched the first digital red packets in the Lunar New Year in 2011. Since then, the feature has become a staple for many social media and communication apps, including Alibaba Group’s DingTalk. Alibaba is the parent company of the South China Morning Post . There are numerous ways that one can gamble on red packets on WeChat, according to the Xinhua report. They range from the gambler having to pay out to everyone in the group if he or she snares the red packet with the smallest face value. One can also bet on the points. For example, a gambler who grabs a red packet of 12.07 yuan will receive 9 points by adding the last three digits of the red packet “2”, “0” and “7”. The person with the highest score wins the game and the points are converted into money when the game ends, according to Xinhua. Tencent’s WeGame platform set to go global, heating up rivalry with Steam “Some gambling organisers have introduced robots for automatic calculation to improve the so-called efficiency,” said Zhang Qian, deputy director of the Investigation and Supervision Department of People’s Procuratorate of Shenzhen’s Nanshan district, according to Xinhua. Compared with illegal casinos or gambling dens, WeChat betting has much lower costs and the closed social-media groups can be frequently changed to avoid detection. “We have some difficulties to suspect and investigate these crimes,” Zhang said. A cottage industry has sprang up over private social-media groups, with individual WeChat accounts going for 15 yuan to 20 yuan while dormant group accounts are going for 230 yuan. Gambling operators and punters buy and use different WeChat accounts to stay ahead of the operator. Tencent has adopted some technical measures to identify and block abnormal WeChat accounts and groups, such as those used in gambling rings.
