I sometimes wonder how many Americans are gambling now. Typically people gamble online with much higher amounts because you have faster access to large sums of money.
There are many restrictions for Americans, but looking purely at casinos that are physically located, I think there is a lot of gambling going on here. Or maybe somewhere in Asia.
I did not know so many people players from Australia.
I just googled the top gambling countries around the world and i see India on top. Maybe Asia will become a new hub for gambling very soon.

Still its one year old results from some articles which actually can't be taken as reference for anything unless they provided valid source from where they took data and made their analysis. Maybe India got more online gamblers but in terms of wagering amount still other country will be top in the list.
