The casinos in Macau, the only place in China where gambling is legal, are struggling. According to Cardplayer, the gambling mecca, which has 35 casinos owned by 6 operators, has seen an increased drop in revenue for 10 months in a row.
The revenue in, for example, February and March this year went down 49 and 39 percent compared to the same two months in 2014. 2015's revenue is expected to be the lowest in four years. The main reason behind these negative results is that fewer Chinese high rollers visit due to the country's strict rules on taking money from mainland. According to Cardplayer, two-thirds of Macau's gaming revenue comes from VIP gamblers.
