Gambling is very addicting and this is because its enjoying for many hours for the most people I know.
Also the fact that money is easy to make with it is the fact why a lot of people are doing it.
It is true that gambling is really addicting but not because of the longer hour we played but because of easy money and that is not that easy to earn it you need to have really lucky enough to earn big and need to control yourselves to get more for your profit so that is not easy thing to do as I know
