I enjoy playing blackjack now and again, and poker is fun to play with friends. I don't gamble to "win big bucks" - I accept any losses as the cost of a night of entertainment, and any winnings are just icing.
Slots though, ugh, zero skill, almost zero fun. My wife likes em though.
Usually, though, if I go to the casino, is to join my wife and parents who both like it, and I just enjoy the free soda
