Asia Pacific's gaming industry continues to be buoyant despite various challenges, S&P Global Ratings said in a Wednesday release.

Headwinds for the industry include an unstable microenvironment, labor constraints, and a slower monetary policy easing from the US Federal Reserve, S&P said.

However, premium mass gaming involving affluent players and higher product stickiness with players remaining engaged serve as main factors for the sector's strong performance, the rating agency said.
