Best Welcome Bonus Online Casino USA

After scouring the world wide web for the best US casino offers, we have compiled a list of the most lucrative and exciting newplayer welcome packages. On these sites, you can secure massive bonuses and use them to play a massive array of epic casino games.

Welcome bonuses serve as one of the best incentives to register on an online casino, taking priority over the game selection for new players. Many of these bonuses allow you to try out games for free and grow your bankroll as a new player.

With some states already offering legal online gambling and more looking to join the list, the number of online casinos operating in the US keeps growing. However, not all sites provide top-quality welcome bonuses. Some sites have a high wagering requirement, short expiry date, and game restrictions that diminish the quality of their bonuses.

This guide provides a selection of the best welcome bonuses from online casinos in the USA. The casinos on our list have licenses in specific US states, making them excellent options for legal online gambling.

#5 Borgata Online Casino: Best for Poker and Bingo Welcome offers

  • Available States: New Jersey, Pennsylvania
  • Welcome Bonus Type: Bonus cash + Deposit Match
  • Existing Player Bonuses: Yes (Referral Bonus, Seasonal Bonuses, Daily Bonuses, Rewards Program)

The welcome offer at Borgata Casino is one of the best since it includes bonus cash and a deposit match, with other options such as Borgata Poker and Borgata Bingo welcome offers available.

Borgata Casino Welcome Bonus

The Borgata Casino welcome bonus is a $20 bonus and a 100% match up to $1,000 when you use the bonus code GUSA. You can start playing with the bonus after registering on the site, but you must complete its wagering requirement and make an initial deposit if you want to withdraw your winnings.

  • You must meet the wagering requirement on the match bonus 14 days after making your deposit.

  • The $20 bonus cash cannot be used on Poker and Jackpot Slots.
  • There is a 1x wagering requirement and seven days to meet the requirements for the cash bonus.
  • Slots, scratch cards, virtual games, jackpot slots, and fixed odd games contribute 100% towards the wagering requirement, while non-live dealer Blackjack contributes 10%.

$20 Free Play & $1,000 Matched Bonus

#6 Golden Nugget Online Casino: Best for Bonus Spins

  • Available States: Michigan, New Jersey, West Virginia
  • Welcome Bonus Type: Match Bonus + Bonus Spins
  • Existing Player Bonuses: Rewards Program, Weekly Promos, and Special Bonuses

The Golden Nugget Casino welcome offer features the regular match bonus, giving new players a 100% match up to $1,000 on their first deposit. The icing on this offer is 200 bonus spins to play a specific slot title.

Golden Nugget Casino Welcome Bonus

We have an issue with the Golden Nugget Casino match offer: the wagering requirement applies to the initial deposit plus the bonus. Hence, if you make a $500 deposit for a $500 match bonus with the 10x wagering requirement, you must wager $10,000 ($500+$500 x 10) to meet this requirement as opposed to the $5,000 requirement with regular bonuses.

The inclusion of a spins bonus makes it an excellent option for new players who want to get a headstart. However, limiting the bonus spins to one slot is a minor inconvenience.

Golden Nugget Casino Bonus Terms and Conditions

  • Players must deposit at least $30 to claim the welcome bonus.
  • The bonus applies to a single deposit.
  • Bonus spins are available for seven days after receipt.
  • There is a 10x wagering requirement on the welcome offer.
  • A 1x wagering requirement applies to winnings from bonus spins.
  • All slot games contribute 100% towards the wagering requirement, except ten specific titles that contribute only 25%.
  • Roulette, Blackjack, Baccarat, Video poker, and Table games contribute 25%.


  • You can use the bonus on slots, table games, Baccarat, Blackjack, Video poker, and roulette titles
  • The welcome bonus has a low wagering requirement and thirty days before it expires
  • Winnings from the bonus spins only have a 1x wagering requirement


  • The welcome offer wagering requirement is higher than what is stated by the casino
  • The casino will exhaust your funds before letting you play with bonus cash
$50 in Casino Credits with a min. deposit of $5

#7 Mohegan Sun Online Casino: Best CT Casino Bonus

  • Available States: New Jersey, Connecticut
  • Welcome Bonus Type: Match Bonus
  • Existing Player Bonuses: Yes (Daily Spin, VIP Exclusive bonuses)

The Mohegan Sun land-based casinos are popular around the US, but only a few casino lovers know about its online casino. Mohegan Sun slots are definitely one of the casino’s strongpoints and one of the main reasons to check the site out.

Things to Know with Online Casino Welcome Bonuses

Online casino bonuses are great for new players, but there are certain things you should know before you claim your first bonus. These include the following:

They are not available in all US states

An important thing to note is that you cannot access online casino bonuses in all US states for two main reasons. The first reason is that online casinos are legal in only six US states; Connecticut, Delaware, MichiganNew JerseyPennsylvania, and West Virginia.

Secondly, each online casino is legal in specific states. Since each US state is responsible for regulating online casino operations, each casino must get a license to operate in a state. For this reason, it is common to find top online casinos that operate in two, three, or four states but not all legal states.

A minimum deposit is required

Although some online casinos offer no deposit welcome offers on sign-up, all the best welcome bonuses require a deposit. These deposits are standard on the match bonuses, and they help the casino determine how serious you’re about becoming a member.

The minimum deposits vary, and online casinos accept $5, $10, $20, or $30 as their minimum. Thankfully, one of the top online casinos, DraftKings, accepts deposits as low as $5 for its bonus.

However, making the minimum deposit isn’t recommended if you want to maximize your returns from a match bonus offer.

Wagering requirements apply

Online casino bonuses often have wagering requirements; some may be more restrictive than others. There are several reasons for imposing these requirements, and the drive to dissuade players from abusing a bonus offer is one of the most crucial to online casinos.

Another clever reason for these wagering requirements is to prevent money laundering through online casinos. Without the requirements, criminals can instantly deposit and withdraw their funds from these casinos.

If you receive a $500 bonus with a 10x wagering requirement, it means you need to wager $5,000 before the bonus winnings become available for withdrawal.

You cannot use them on any game

This restriction varies from casino to casino, but online casinos usually restrict access to certain games when you’re playing with their bonus offers. The restriction from the online casino may apply to an entire category (say all Baccarat Games), or specific games in a category (like the Blood Suckers slot) with high RTP and low house edge.

If an online casino allows you to use bonuses to play any game on its site, there is usually a game contribution that you must consider. Slots typically offer 100% contribution, so, for a $100 bonus with a 10x wagering requirement, you need to wager $1,000 to meet the requirement.

On the other hand, for the exact requirements with Blackjack games contributing 10%, you must wager $10,000 ($1,000/0.1) to meet the wagering requirement.

You may need a bonus code

Not all online casinos require a bonus code, but some do. The unique codes give you access to the welcome bonus on the casino, and others may unlock a special welcome offer depending on where you get the code.

We have unique bonus codes for specific casinos, and we list them alongside the bonus offers you find on Gamble USA. You must use these bonuses according to how the casino instructs, as any action otherwise may lock you out of the opportunity to claim the bonus.

Online casino bonuses expire

Only some new players know about this, but online casino bonuses can expire. The site will provide the expiry date on its bonus terms and conditions page, so be sure to go through this page.

You must complete the bonus wagering requirement within the period before it expires if you intend to withdraw your bonus winnings. If you cannot meet the requirement before the bonus expires, the casino will remove your remaining bonus funds and winnings from your account.

There might be more than one welcome bonus available

Some online casinos offer more than one welcome bonus to players, so you can choose a bonus that meets your needs. This may be a casino welcome bonus in addition to a Bingo welcome bonus or Poker welcome bonus. In most cases, claiming either the Bingo welcome bonus or Poker welcome bonus locks you out of the casino welcome offer.

Why Are These The Best Online Casino Welcome Bonuses?

Online casino bonuses have become a standard across the industry, and welcome bonuses are available on most sites. With the competition between online casinos trying to attract new players to their sites, the quality of bonus offers varies vastly.

Some casino bonuses aren’t worth your time, and others provide everything you need to test their games, and win bonus money. There are several factors to consider when picking the best online casino bonuses. These factors help you determine online casino bonuses worth your time.

The factors we consider when creating our list of top online casinos include the following:

  1. The wagering requirements of the bonus – the lower the better.
  2. How long are the bonus funds or bonus spins you receive going to be valid?
  3. Games you can play with the bonus – are they games you love to play?
  4. Overall game selection of the online casino.
  5. Licensing and authenticity of the site.
  6. Availability of top-quality payment options.
  7. Assessment of the general bonus terms and conditions

Our top recommended casino bonuses meet these requirements and picking bonuses according to this checklist will give you the best results.

Ultimately, our team considers the BetMGM Casino bonus the best welcome bonus in the USA.
