Economic benefits of casinos for tourism
If we consider the impact of casinos on tourism, they certainly create an incentive to visit regions like Goa and Sikkim. First, casinos attract tourists who spend money not only on gambling, but also on hotels, restaurants, and stores. This revitalizes the local economy and creates jobs - both in the gambling industry itself and in related fields. For example, in Goa, casinos generate millions of dollars in tax revenue, which helps develop infrastructure and tourist areas. Of course, one should not forget about possible risks, such as increased social tension or gambling problems. However, if we talk exclusively about economic aspects, the impact of casinos on tourism in India is rather positive.

The question is rather how effectively this sphere is regulated in order to minimize the negative effects and maximize the economic benefits.
I think it all depends on how it is organized. In one region, casinos can be a powerful driver of development, and in another region they can cause more problems than benefits. In Goa, for example, it is part of the entertainment industry and it seems to be making money.
