Spurred by rising disposable income, a strong appetite for gambling and more sophisticated games, China's lottery market has boomed with customers splurging some $23 billion in 2012, compared to $37 billion by punters in the world's biggest lottery market in the United States. With 20 percent growth rates projected for the next three years, China is expected to overtake the United States and leap into the top spot by 2015. Picture taken December 29, 2013.
