How to Choose an Online Casino USA

Those new to online gambling may find choosing an online casino a challenging task. However, if you keep things simple and follow this guide and our casino reviews, it’ll become clear it’s a very easy and enjoyable process.

Safe and Secure Site

When sharing personal and financial information, the most important factor in choosing an online casino must be the site’s security.

Before signing up, be sure that it’s licensed, regulated and information is encrypted, which can be verified by noting a little padlock near the web address bar. By being licensed and regulated by third parties, you can rest assured that the online casino you’re considering is safe.

Welcome Bonuses

If you like FREE money, and who doesn’t, be on the look out for online casino welcome bonuses.

Just for signing up and making a first deposit, most sites will offer generous promotions that match, double, triple or more your original deposit. Plus, for those who like to play online slots, many sites offer FREE spins in addition to their welcome bonus monies.

Easy to Make Deposits

The casinos that accept the most deposit methods are often the most reputable.

In most cases, these sites accept credit cards, e-wallet funds and, more recently, cryptocurrencies like Bitcoin. It should take new players no more than a few minutes to make a first deposit. If the process to deposit takes longer, that’s a red flag that you should look elsewhere.

Wide Range of Games

The saying goes, the more the merrier and same can be said of online casino’s slate of games.

New players seeking out a gambling site should be on the look out for table games, like blackjack, specialty games like baccarat and a more than 100 slot offerings. All are signs of a quality casino.

Mobile Gaming

Technological advances in gaming software and security have allowed our recommended casinos to offer the same experience once enjoyed on a personal computer to now be enjoyed while on the go with mobile gaming sessions that can be fired up via a web browser in the palm of your hand.

Fast Payouts

If waiting is the hardest part, you’ll find that the best online casinos offer quick payouts when you’re ready to withdrawal.

A little word to the wise, if you really want the fastest payout possible, be sure to make a deposit with cryptocurrencies as some of those requests can be processed same day.

Online Casino Strategy

Manage Your Bankroll

We cannot stress this enough, and you’ll see this everywhere on our site. Have a wagering strategy, don’t bet more than you can afford to lose, and never chase losses.

Play Games You Understand

It seems silly to have to recommend this, but know the rules of the games you play. Read our guides, know the odds, and don’t waste money playing a game you don’t understand.

Find A Great Bonus

Whether it’s a welcome bonus, free spins, a VIP program, or something else entirely, the best US casinos reward you just for signing up. If they’re not offering a bonus, walk away.

Casino Bonuses

On the note of bonuses, we simply cannot underestimate their importance to both the player and casinos in the USA. Bonuses are often how operators differentiate themselves against their competition, while players get the added advantage of free spins, or a little extra bankroll to play with.

Welcome Bonus

Welcome bonuses are how casinos in the USA roll out the red carpet for new players.

A welcome bonus is typically a match deposit, meaning the casino would match your initial deposit 100%, up to a certain amount. For example, if you deposit $100, the casino would give you $100 free to play with… For those of you keeping score at home, that means you’ve just doubled your bankroll before even placing a bet.

Free Spins Bonus

A free spins bonus is exactly what it sounds like – casinos will often offer a set number of free spins on slots games to new players.

Free spins can also be included in the welcome bonus or can come on their own. These free spins can be used to sweeten other offers, or they can be used to help promote a new online slot game that the casino is promoting. Free spins are a great way to try out new games.

No Deposit Bonus

A no-deposit bonus is also aptly named: this is a (less common) bonus offered with zero commitment from the player. Simply sign up, and they’ll send the bonus you’re way, whether that’s a boost to your bankroll or some free spins.

Reload Bonus

A reload bonus is one that’s built for returning players. Typically not as generous as the welcome bonus but with a similar structure, casino operators will match part of a returning player’s deposit up to a certain amount.

Loyalty and VIP Programs

While loyalty programs used to just be for high rollers, many casino outlets will enroll new players into their loyalty/VIP programs as soon as they sign up.

While each program is slightly different, generally the more you play, the more points you earn, and you can move up through a tiered system.

Common rewards include dedicated account managers, higher limits for deposits and withdrawals, and sometimes even additional bankroll.

We encourage all of you to visit our gambling addiction resource page where you’ll learn about different types of gaming addiction, gambling symptoms, treatment options and valuable affiliate resources from Gambler’s Anonymous to the Mayo Clinic.
