Macau's gambling revenue defied China's economic slowdown and rose 20 per cent in July year-on-year.

Revenue was boosted by an increase in the number of Chinese visitors to the country's only legal casino gambling hub, as well as the size of their bets.

July's US$3.7bn revenue was the third strongest figure this year, as more middle-class gamblers visited Macau, eclipsing the growth in the number of high rollers.

The slowdown in China's economic growth has kept away some wealthy customers, but it failed to dull Macau's appeal for China's rapidly expanding middle class and their higher disposable incomes.

Infrastructure projects currently in the works, including an expansion of high-speed railway links to Chinese cities and a bridge to Hong Kong and Zhuhai, are also likely to increase the number of middle-class visitors in the next few years.

Macau's casinos are trying to diversify entertainment options to attract more of these visitors. MGM China has built a temporary indoor aquarium while Galaxy Entertainment has built a wave pool and a beach at its resort.
