These days gambling is fun and enjoying and you can play whatever game you want for money but due to that it also provides a lot of problems for some people.
They get greedy and addicted and wil get in problems soon or later, I think that gambling is not wrong but that you have to control it.
I think it is really how gambling is designed. Sneaky to make you off guard and then strike and wake your greed while you are enjoying the game. Little that we know we are hooked on the gambling game little by little until an issue occurs.
