Haha! To be honest, i have never been into any of the land casinos in my country, For many years, our government resisted calls to set up casinos. Eventually The first casino, located within the Resorts World Sentosa integrated resort, opened on 14 February 2010. The second casino, housed in the Marina Bay Sands integrated resort, opened two months later on 27 April 2010.  
The casino entry levies for Singaporeans and permanent residents visiting the two integrated resorts (IRs)  will rise to $150 from $100 currently while the annual entry levy will increase to $3,000 from $2,000, in April 2019.
 Seriously if you are talking about real gamblers, they would have already set their mind on winning back those levy fees once they gets in. Sad to say...
Anyway i would prefer gambling online at my comfort zone. Gets more game varieties from different sites and own time own winning target. I hate crowded places. Lol!
