How we rank the best online casinos: Factors we assessed

There is no shortage of online casinos in the USA, and some of the best legal gambling sites are right here in this piece. Each one has its own qualities.

Sign-Up Offers

Perhaps one of the most important factors for us is the sign-up bonus available for new customers. Getting a great start to life at a new online casino is of the utmost importance and one of our key factors in rating them.

The most common types of sign-up offers are as follows:

• Deposit-Match Bonus
• No Deposit Bonus
• Free Spins
• Bonus Funds

Many of the welcome bonuses have requirements, so we take into consideration the lengths and difficulty of claiming them. Some of the aspects we look into were:

• Does the bonus have large wagering requirements?
• How long is the bonus active for?
• What games can I use the bonus funds on?
• Is everyone eligible to claim the bonus? 
• What is the maximum amount you can win with bonus funds?

If we are satisfied that a bonus answers all these questions, and the sign-up offer is a strong one, then that’s a major plus in our eyes.

Variety of Games

The content and depth of games are also right up there as one of the most important ranking factors for the best online casinos. We scanned and tested a number of games at all the online casinos in this piece to see how fun, profitable, and easy they are to play.

A common misconception could be that the more choices you have to play, the better, but we found this not always to be the case. For us, the quality of gambling options was a priority, despite some casino sites offering as many as 1,000 different games.

Most online casinos will offer the same most popular casino games, so if you’re after a specific one, it’s worth taking a look around to see which offers that choice.

Payment Methods

While it’s not always easy, generally, the best online casino sites will accept a wider range of deposit and withdrawal options and are more trustworthy.

Each online casino will have a different preferred method, so it was important for us to check which offers the most variety. In this case, the more payment options offered, the better, as this means more players will be able to enjoy the benefits of the online casino. 

Speed of transaction was also taken into consideration, as the best online casinos will allow you to deposit or withdraw your money within minutes.

Existing Promotions

All of the best online casinos will offer some sort of welcome offer, but not everyone offers existing promotions. These are fantastic incentives, which real money gambling sites use to keep you returning to their casino and give you more incentive to play.

Many of the best online gambling sites will provide their existing customers with rolling incentives, bonus funds, free spins, and much more. We assessed the different existing promotions.

Mobile App

Nowadays, one of the best and most popular ways to play at an online casino is on your mobile phone. This means downloading an online casino app and playing where and whenever you want. All of the casinos in this piece have mobile apps, but we tested them so you don’t have to. 

There were many things considered, such as the speed at which the app interface loads, how easy the app is to use, and how similar the app is to the full desktop version. In our eyes, the mobile experience needs to be as similar to the desktop site as possible, meaning you get the full online casino experience on an app.

Bally Casino

888 Casino

On the whole, 888 Casino is a fantastic online gambling site, with their wide options of slots and games available. The ability to use the casino on mobile devices is right up there as one of the best. 

Fans of slots and blackjack games will particularly enjoy the variety they have to offer. 

Their live casino is not available 24 hours a day, which is an aspect we’d like to see added in. However, 888 Casino is still a great option to go with for those looking for a site to play their favorite casino games.

Hard Rock Casino

Hard Rock boasts an impressive casino, with their selection of slots and poker games being particularly appealing. Their live casino section, as well as the blackjack games they have on offer, are also good, making them a very competitive casino site. 

They could improve in some areas, such as by offering users the chance to wager on virtual sports, as well as more withdrawal methods.

However, overall Hard Rock Casino is definitely worth your time.

Harrah’s Casino is a great choice for your online casino action, with their poker and slot offerings proving to be two of their strong points. 

They also offer a top-of-the-range selection of jackpot slots, with their blackjack options also proving to be decent. It has to be said that there are some areas of Harrah’s Casino that can be improved, such as the fact that they currently don’t offer any live casino games, variety games, or virtual sports for you to play. 

Despite this, it’s fair to say that Harrah’s Casino is still quite impressive, so we’d recommend heading over and giving it a try.

Online Casino bonuses explained

All of the online casinos mentioned have fantastic new customer offers and bonuses, which you are able to take advantage of. However, there are a few different sign-up bonuses, which can sometimes be difficult to understand. Take a look at the different offers available, and you’ll be sure to understand how they work when you sign up to a new online casino.

Deposit Bonus

No Deposit Bonuses

Online casinos offer no-deposit bonuses to new players who have just created an account. This is an instant bonus, with no deposit needed to claim. Essentially, this is an online casino’s way of saying ‘thank you’. 

New players can claim no-deposit bonuses even before making a first deposit. Usually, none are in the form of small cash bonuses or free spins.

Second Chance Opportunity

A new, interesting bonus offer, which many online casinos do not offer. This promotion entails a certain period of time in which your wagering is eligible for a ‘Second Chance Opportunity’. For example, a real money online casino may offer you a ‘Second Chance Opportunity’ on your first 24 hours of casino play up to $1,000. This means that any losses accrued during this period of time will be paid back to you in the form of casino bonus funds. Be aware that the bonus funds will have wagering requirements. 

Where are Online Casinos legal? 

Online Casino States: Coming Soon

While online sports betting is moving swiftly across the US, the same cannot be said for online casinos. It is not clear when Indiana will soften its stance on online casino gaming. There has been talk Illinois and Indiana might legalize it in 2023, and if this were to happen, it could open the door for online casinos in many states across the country. However, there has been no concrete evidence of a launch, merely whispers. 

Given the rapid expansion of online legal sports betting in the USA, once more states legalize online casinos, we at the Post expect it to spread rapidly.
