I need advice since I only know the general rules for gambling. Is online casino legal? Do they really pay out your winnings honestly? What game would you choose if you were a beginner? I apologize for asking about everything at once. I really need help ..

You could just read more information on the casino blog. I also recommend using reviews and a list of top-rated gambling sites in the US. I found my favorite site myself. Here it is - https://bettingcasinoslots.com/ I usually prefer mini-games as they don't require high stakes. Try starting with slots. Then you yourself will understand what gives you the greatest luck.
