No confusing terms. Just what you actually need to know before you sign up.
A "sportsbook" is an app where you can legally bet real money on sports. An online "casino" is an app with real-money slots and table games. Both are regulated the same way a bank or casino is — not some sketchy website.
Yes, as long as the operator is licensed in your state and you're old enough (21 in most states, 18 in a few). Every operator on this site is licensed and regulated — that's the whole point of the list.
Free bonus money or bonus bets you get just for signing up and making a small first deposit — usually $5–$10. It's how these apps compete for new customers.
Pick an operator below, tap "Sign up," enter your details and ID (required by law), deposit a small amount, and you're in. Takes about 5 minutes.
The easiest app to figure out if you've never done this before, with the widest state availability, so it's more likely to actually work where you live.

Casino availability is far narrower than sportsbook availability — online casino gambling is regulated separately in the US and is currently legal in only about 7 states, versus 30+ for sports betting.
A sportsbook is for betting on sports (like an NFL game). A casino app is for slots, blackjack, roulette, and similar games. Some companies offer both — you just pick which one you want when you sign up.
Only in certain states, and it depends whether you mean sports betting (legal in about 30 states) or casino games (legal in about 7 states). Every app checks your location automatically and won't let you play if it's not legal where you are — so if it doesn't work, that's usually why.
It's real bonus money, but it usually comes with rules — like having to bet it once before you can withdraw. Don't assume the headline number is money you can just take out right away. Each operator's sign-up page spells out the exact rules.
Yes — some of the links on this page pay us a commission if you sign up. It costs you nothing extra, and it doesn't change which operator we rank higher. Full details are in the disclosure below.
Stop, and reach out — see the phone numbers in the footer below, they're free and confidential. Every operator also lets you set spending limits or pause your own account, right from the settings menu.
