yes it is also a good way but the interest and entertainment was little bit slow when comparing to the gambling with the normal online games that is the difference between them the Hype and the interest was increased in gambling only that is the reason lots of people doing it.
I'm more entertained with online games if I'm playing the game of my interest. But there's also a time that when I'm in mood I like to play gambling games of my choice.
I just can't read my mind, sometimes I'm into games online or offline and sometimes I just want to gamble.
