Singapore's first destination-style casino opened in February, 2010, so the self-exclusion program that the government had established for permanent residents and citizens (but not for non-resident foreigners) has become relevant. As of last week, 264 people had applied for self-exclusion. A second resort casino in Singapore is now scheduled to open in April, and the exclusion orders will apply to both locations.
Beyond standard self-exclusion, Singapore offers "Family Exclusion" possibilities: a close family member can apply to have another family member excluded from the casinos. The application sets in motion an inquiry, and if a panel decides that the gambler in question is engaged in problem gambling, the exclusion will be granted -- even if the decision is counter to the wishes of the gambler him or herself. So far, 31 people have been excluded through this family intervention process.
The new casino allows people to pre-specify loss limits, but so far, no customers have imposed them. For internet gambling, I think there is something to be said for mandatory choice of pre-specified loss limits, as well as time constraints.
