What to Consider when Searching for the Biggest US Online Casinos
When it comes to the biggest online casinos in the United States, you will notice that all of them compete against each other to provide the ultimate gaming experience. Some might have a massive portfolio of the biggest games, while others impress with the biggest selection of payment options. However, if you are a newcomer in the gambling environment, it's nearly impossible to determine which US online casino is best suited for you. It's for this very reason that we compiled a big list of things to consider when searching for your next online gambling establishment in the US.
- Legality: This is undoubtedly the most important factor to consider when looking for the best and biggest US online casinos. You will need to ensure that the operator is licensed and regulated by a reputable offshore jurisdiction or that the gambling site is legal in your state. Failure to do so will result in disappointment and heartbreak.
- Payment Options: The second most important factor when it comes to finding an online casino in the USA is to ensure you have a big selection of payment methods at your disposal. The online casino operator can impress with the biggest game selection, the best software, and superior customer support but if you can't fund your account, the rest of the features are rather pointless. There's no advantage in the biggest suite of games if you can't play them.
- Software Developers: You will need to make a list of your favorite big casino games and find out which software developers produce them before you choose one of the biggest online operators in the US. This will make your search far more straightforward.
- Customer Support: You essentially want the biggest gambling establishment that comes equipped with 24/7 customer support that can also be reached through several contact channels, such as telephone, live chat, and email.
- Game Selection: This is another important aspect that requires loads of attention. Always remember that the biggest selection of games will give you more hours of entertainment and fun.
What is a No Deposit Offer?

Once you've settled with one of the biggest online casinos in the US, you will need to test the casino software, evaluate the game variety, and determine if the support center is up to the task when you contact them with a simple query. The best way to achieve this without spending your own hard-earned money is to use a no deposit deal, offered by most big sites. Not sure what this is? Don't worry, we got you covered!
This offer comes in many shapes and sizes and can vary from small to very big, but all of them essentially give you free money without having to first make a purchase on your account. You can either claim a free spin offer, a free cash offer, or a free play promotion to get you started. Most of the biggest US online casinos will give you between 10 and 50 free games upon registration on a popular slot title, while others will allocate free money that usually ranges between $5.00 and $20.00 - though the biggest may have tougher wagering requirements. You will even find some of the biggest gambling sites will allow you to play for free for an hour with free play money before you'll need to make a deposit to keep your winnings.
It's also worth mentioning that these no deposit offers, whether small or big, will sometimes require a coupon or a promo code to receive the promotion on your account, especially when it comes to no deposit bonuses or no deposit free spins. The coupon needs to be entered during account registration to receive the offer or you will need to contact customer support before it's allocated to your account. Occasionally the biggest US online casino promos are automatically activated upon account creation, crediting players from the US with introductory bonuses without the player having to do anything extra.
What is a Match Deposit Offer?
Once you've tested the biggest US gambling sites of your liking with a no deposit offer, and you are satisfied with everything on the site, you can go ahead and make your first purchase. However, before you register your payment method and enter the amount you want to purchase, look for the biggest match deposit offer specifically designed for your initial payment.
A match deposit offer is a fantastic way to start your adventure in the online gaming community as it basically doubles your balance, allowing you to play with the biggest sum possible. A match deposit offer is also known as a welcome package and it usually offers customers a 100% bonus on their initial purchase, (although bigger rates of 200-300% are sometimes on the cards). So, if you decide to make a $50.00 purchase, you will automatically receive a $50.00 bonus, giving you $100.00 to play with at the casino.
Types of Ongoing Promotions

Once you've claimed the biggest and best match deposit offer you can find, you will be pleased to know that there are a plethora of other ongoing promotions worth your time and money. The different types of ongoing promotions include Reload Bonuses, Loyalty Bonuses, Complimentary Bonuses, and Cashback Offers.
A Reload bonus is usually available on a daily or weekly basis and functions in a similar way to the match deposit offer. However, the match percentage will be smaller, offering you a bonus of between 10% and 50% of your deposit size. The biggest promos might come with a rate of up to 70% or so, but the threshold of deposits will still be lower than for welcome bonuses (which might be up to hundreds or even thousands of dollars).
Cashback offers are also extremely popular among US players as you essentially get a percentage of your losses back every week or at the end of every month. Most USA casinos provide a 10% cashback deal, while the biggest can be as high as 20% back on your overall losses.
Perhaps the biggest and best recurring promo at US online casinos is the VIP or Loyalty Club. These clubs operate by giving US players points every time they wager. Once sufficient points are amassed these can be exchanged for rewards, from small online casino bonuses like free cash through to the biggest, which might be top class sports tickets. These types of clubs frequently feature multiple tiers, with bigger points earnings at higher levels. Some US online casinos even offer regular lottery-sized draws, with those in the upper echelons of the club in with a shot of cash prizes as big as seven or eight figures.
The Biggest Slot Jackpots Online
Now that you know the ins and outs of some of the biggest casinos in the US, it's time to discover the most lucrative progressive jackpots when it comes to online video slots. Below, you will find a list of the biggest progressive jackpot slots available at US casinos that are bound to change your life forever if you are lucky enough to unlock the large sum of money within each game.

- RTG's Aztec's Millions Slot: $3.515.330
- Playtech's Gladiator Slot: $3,228,783
- Yggdrasil's Joker Millions Slot: $2,441,636
- Playtech's Funky Fruits Slot: $2,467,217
Safe US Casino Banking Methods
The biggest battle you'll face when choosing a US online casino is whether or not you'll be able to deposit funds or withdraw your winnings from your account. The reason for this is that many US-facing casinos don't offer a big selection of banking options which makes it nearly impossible to transact on your account.
It's for this very reason that we urge you to look for gambling sites in America that provide the biggest selection of payment methods for both your deposit and withdrawal needs. We highly recommend looking for an online operator that comes equipped with Visa and Mastercard Credit/Debit card options, Neteller, American Express, Bitcoin, and Wire Transfer options.
Players from the US have never had more online casinos at which to play the biggest range of games, whether on desktop or mobile devices. Better yet, there's a great range of US online casino bonuses and the biggest can be worth a very tidy sum indeed.
