I like gambling and I see nothing bad in having it just like an other type of hobby.
And speaking about my favourite games... Well, I adore poker, blackjack and online casinos, especially slots
Quick Hit and roulette for them. But from my own experience I should mention that you should be careful with online ones, if you want to play, than it's really better to choose only licensed sites, there's much scam in this sphere and sometimes people had very unplesant issues with their bank cards because of this.
