Pierced Angel,
I still do play roulette sometimes. The house only has a margin of 2.7% in the UK, which isn't bad at all. Note though that UK rules only allow for a single zero and 36 numbers, as you get odds paid of 36 - 1 on a 37 section roulette wheel that equals 2.7% casino advantage.
Now, if you play in the USA or Monte Carlo, you will see that the wheel also has a double zero. That means paid odds of 36 -1 on 38 sections, that equals a casino advantage of 5.27%. At this point you are only playing for fun, it is highly unlikely that you can win unless you just play for a few minutes and stop if you win.
Blackjack is OK, if you are new to the game I suggest that you dont sit at the end of the table. Your bet will be just before the croupiers deal, and can affect the winnings of the players to one side of you.
Slots are totally hopeless. Forget it.
