How legal online gambling ? Online gambling, also called Internet gambling, is completely legal in some countries, where its entirely available on unregulated and state-licensed online casinos and online sportsbooks. However, the question still stands: is it legal? How can we know if something is or isnt legal? First, lets look at the history of online gambling in Philippines. Ever since the late 1990s, when Filipino businessmen began opening up internet casinos, there has been an explosive growth of the Filipino gambling market. The government has approved it because the vast majority of the population is now using computers, and that the internet has opened up a virtually untapped market in PH. At the same time, Philippines has also allowed for a bit of free enterprise - after all, it would be impossible to have a thriving gambling market without people putting money into it.
