My advice, don't gamble what you can't afford to lose. Whatever you win over what you brought, keep half, and when you lose the rest, stop. If you can't, run don't walk away from the situation.
I have played cards for money at work, cribbage, pinochle, poker, hearts, etc. I also play in tournaments and with the in-laws (who fight over who will be my partner).
The only game at the casino that is in your favor is blackjack if you can count cards. But even someone with a fairly good system can walk away winners. Next, roulette is almost an even bet against the house. All the rest is "hand your money over to the casino." But if you enjoy it, why not? Just don't bet the house payment or the kid's education money.
