I will tell you the major countries where online gambling is legal, breaking it down by continent or sub-continent. Some of these countries also have restrictions, limiting online gambling to specific games or sports. There are many countries where gambling is legal, but in some, it is not. My usual sites were blocked in the country I was in, so I decided to do some research. When I was looking into gambling while abroad, I ran into some trouble finding legal sites to gamble on.
