[Closed: Casinos, accepting US Players - Quick Check List!]

Do you know of any USA casinos that are also Mac Compatible?

[Total newbie here - questions]

I've gambled IRL, but never online for real money. I'm aware there are many scam sites that don't pay, hence the reason I googled forums first!

I have many questions, some of which I'm sure have already been answered. Apology upfront for being repetitive.

1. USA legalities- what makes the difference in being legal or illegal? I've seen some sites pay in bit coins, Skrill, or other alternantive money.

2 should I use a VPN to register so my USA residency remains undetected?

3 what sites are best for USA PLAYERS?

4 why are some online casinos and others are downloads?
