The number of individuals excluded from entering Singapore’s two casinos rose 15% in 2015.

According to the city-state’s National Council on Problem Gambling, 2015 closed with 277,500 active cases of individuals who weren’t allowed into either Las Vegas Sands’ Marina Bay Sands or Genting’s Resorts World Sentosa.

Around 233,500 (84%) of these cases are individuals who have submitted their own names for exclusion. The vast majority (215,000) were foreign nationals who either work in or routinely travel to Singapore. Nearly 1,100 individuals voluntarily filed to limit the number of times per month they can visit casinos, 63% more than exercised this option in 2014.

Singapore allows relatives of problem gamblers to file applications to exclude their loved ones from the two casinos but these cases represented less than 1% of the total cases at the end of 2015.
