How We Select the Top Online Casinos
There are a lot of factors our team looks at when comparing the best online casinos in the US. Here, we’ll explain some of the key elements we consider.
Range of Games
The first thing we look at when evaluating free online casinos is what types of games they offer and how many games they have in all. Top online casinos offer slots and classic games like blackjack, roulette, and poker. Plus, many of the best online casinos introduce new games frequently to keep things exciting for players.
Software
The best real money online casino sites use industry-leading software from providers like NetEnt, BetSoft, Real Time Gaming, and others. These software providers have proven that they can deliver fun, user-friendly games with good payouts and fair dealing. Many casinos, like Bovada and BetOnline, use multiple software providers to deliver an even better user experience.
Welcome Bonuses
Welcome bonus offers at free online casinos can add up to a lot of money – to the tune of $3,000 at BetUS or $5,000 at Wild Casino. So, these offers play an important role when we’re comparing online casinos. We’ll talk about welcome bonuses in more detail later in this guide.
Betting Limits
Betting limits control the minimum and maximum that you can bet on a single slots pull, a single roulette roll, or a single hand of blackjack. While some casinos limit you to just a few hundred dollars, you can find high roller tables at Bovada that let you bet up to $2,500 per hand of blackjack.
Live Gaming
Live casinos enable you to play games like blackjack, roulette, and baccarat with a real human dealer over video chat. That gives you the traditional casino experience even as you play on your computer or smartphone. Most live dealer tables are available 24/7, and casino gambling sites like Ignition may offer multiple tables so you can choose your dealer and table limits.
Payments
Seamless payments are essential when you’re playing with online casinos for real money. All of the casinos we reviewed let you deposit funds by credit card, debit card, or cryptocurrency. Withdrawals are also quick – typically within 1-3 days – and completely fee-free.
Mobile Experience
Nearly all of the top online casinos now offer mobile apps or mobile-friendly websites alongside their desktop-oriented websites. On most mobile casino apps, you’ll have access to the same range of games, payment methods, and customer support. All of the casinos we recommended have apps that are relatively easy to use, too.
Security
Of course, online security is an important consideration when you’re playing with an online casino for real money. We checked all of the casinos we recommended for safety. All of them are legit online casinos that use advanced encryption and ID verification to keep your accounts safe. Many have decades of experience protecting players’ funds.
Are Online Casinos Legal in the US?
Online casinos are now legal in 7 states: New Jersey, Pennsylvania, West Virginia, Connecticut, Michigan, Delaware, and Nevada. If you’re outside of these states, playing online casino games for real money is banned.
Even within these states, though, the rules around online casinos can be confusing. Some states only allow certain types of games, and all of them put limits on which online casinos you can actually play with. This leads to less competitive online casino markets, with lower payouts and higher fees for players.
Playing with Offshore Casinos
The good news is that no matter what state you’re in, you can play online casino games with an offshore casino site. Offshore casinos are based outside the US and aren’t subject to state gaming laws.
It’s important to note that offshore casinos aren’t legal in any state, including the 7 states with legal online casinos. However, this hasn’t stopped millions of Americans from playing casino games online. Enforcement of offshore gaming laws has historically been lax.
What Games Can You Play at the Top Online Casinos?
The best US online casinos offer all the classic games you’d expect to find if you visited the Las Vegas Strip. You can play table games like blackjack, roulette, baccrat, craps, and keno at most top casinos. You can also play hundreds of slot games, including classics like Starburst, Buffalo Fury, and Gonzo’s Quest.
Poker is also a popular game at many of the best online casino USA sites. Nearly all of the casinos we reviewed offer virtual 3-card poker and Hold’em, and casinos like Bovada, BetOnline, and Ignition offer daily poker tournaments. Ignition and BetOnline even offer specific bonuses for playing live poker online.
Increasingly, online casinos are also branching out into new types of games. For example, Intertops casino offers game show games like Monopoly.
Live Dealer Games
Nearly all of the best USA online casinos now offer live dealer games in addition to virtual games. Live dealer games like blackjack and roulette connect you with a real dealer at a real table via video feed, so you get the experience of being on the casino floor no matter where you are.
Live dealer games can have higher table limits than virtual games, which is a plus for high rollers. At Ignition, for example, you can play live blackjack and bet up to $2,500 per hand.
Bonus Offers at Online Casinos
Welcome bonus offers at free online casinos can add up to a lot of money. So, it’s important to understand how these bonuses work and what kinds of conditions they come with.
Matched Deposits
The most common type of bonus offer you’ll see at USA casinos online is a deposit match bonus. With this type of bonus, the amount of cash you receive is based on the size of your initial deposit.
Take the 100% deposit match bonus at Bovada as an example. If you deposit $500, the casino will give you $500. If you deposit $1,000, the casino will give you $1,000. Notably, at Bovada and BetOnline, you’ll also get a 100% deposit match on your second and third deposits.
Free Spins
Free spin offers like the one at Red Dog let you play slots games for free. With a free spin, all the betting lines on the slots game are loaded for you. If any of them win, you get to keep the payout.
Typically, free spins can only be used on one or a few specific slots games – not on any slots in the casino. At Red Dog, for example, the free spins bonus can only be used on the Count Spectacular slots game.
No Deposit Bonuses
An online casino no deposit bonus is a bonus you receive just for signing up. You don’t have to make a deposit to claim the bonus cash or free spins, like you do with most other bonus offers.
That’s a major advantage because it means that you can start playing immediately without risking any money. In fact, if you play through the whole bonus and want to switch to a different casino, you’re completely free to do so. A real money online casino with no deposit bonus effectively lets you play online casino games for free.
Online casinos with real money no deposit bonuses are relatively rare – in fact, none of the top 10 casinos we reviewed offer a no deposit bonus. However, these bonus offers do appear from time to time, so keep your eyes peeled.
Terms and Conditions
As you might expect, welcome bonus offers at the best online casino USA sites do come with a few strings attached. Here are the most important terms to keep in mind:
- Wagering requirement – The wagering requirement is the amount you must wager in total before you can withdraw your initial deposit or your bonus funds. Typically, the wagering requirement is a multiple of your bonus amount. So at Bovada, which has a 25X wagering requirement, you must bet $25,000 if you claim the full $1,000 welcome bonus.
- Valid period – Many online casinos limit how long you have to meet the wagering requirement. At BetUS, the valid period is as short as 14 days. At the end of this valid period, any remaining bonus funds you have will disappear from your account.
- Game limitations – Many welcome bonuses can only be used on a certain selection of games, such as slots and virtual table games. Typically, you cannot use bonus funds to play live dealer games.
