Online Casino Bonuses in the US

Best Casino Bonus USA

US online casinos have huge bonuses for new players.

Online Casino Bonuses in the US can be divided into 3 broad categories: Deposit match bonus, No deposit free money & Free Spins. You can find all 3 types of bonus offers among the best online casino bonuses in the US. Note that these bonuses are only available in the legal online casino gambling states:

Deposit Match Bonuses

Deposit matches are the biggest and most common online casino bonuses in the US. These casino bonuses can range from anywhere between $100 to $1,500. However, you should carefully study the attached terms and conditions for wagering requirements. The best casino bonuses have the biggest bonus amount and the lowest wagering.

Online Casinos with $1,500 Bonus

Only two online casinos offer $1,500 in bonus money. If you want to redeem this huge offer, you need to head either to DraftKings or PokerStars. Compared to European sites, both the casinos have decent wagering requirements for the casino bonus.

Online Casino Bonus Wagering Requirement
DraftKings $1,500 20x
PokerStars $1,500 15x

$1,000 Online Casino Bonuses

The $1,000 casino bonuses are often the best online casino bonuses when it comes to value. Several of the best online casinos in the US give out $1,000 in bonus money. As always, this sign up bonus must be converted to real cash according to the online casinos playthrough requirements.

Online Casino Bonus Wagering Requirement
BetMGM $1,000 20x
Golden Nugget $1,000 20x
Caesars $1,000 10x
Hard Rock $1,000 40x
Borgata $1,000 15x
Resorts $1,000 20x
Mohegan Sun $1,000 30x
WynnBet Michigan $1,000 20x
Party Casino $1,000 15x

$500 Online Casino Bonuses

Online casino bonuses worth $500 do not have the same sound as the four figure bonuses, but they still give out decent value and carry a lower risk for the player. Sometimes these bonuses also come with more relaxed playthrough requirements. And let’s be honest, $500 welcome bonuses for slots and online casino games are still quite a lot.

Online Casino Bonus Wagering Requirement
Hollywood Casino $502 10x
888Casino $500 20x
Ocean Casino $500 30x
Scores Casino $500 20x
Unibet $500 25x
BetAmerica $500 10x

$300 – $100 Casino Bonuses

The smallest category of deposit money for online gambling ranges from $300 to $100. Often available at smaller sites, they might not be the most popular casino bonuses. However, unlike most casinos, those offering smaller match bonuses might have very lenient wagering requirements (just check out the 1x wagering from the BetRivers gambling site!)

Online Casino Bonus Wagering Requirement
BetRivers $250 1x
SugarHouse $250 1x
Harrahs $300 20x
Tropicana $100 1x
Virgin $100 1x
Pala $250 10x

Best Deposit Bonuses from Online Casinos

The award for the best deposit bonus in the USA goes to two different gambling sites. If you are looking for the biggest bonus, with the lowest wagering, head out to Caesars and grab a $1,000 match with a 10x playthrough requirement if you just play slots. However, if you want to get the most out of your money, take the $250 bonus from BetRivers / SugarHouse and just play through your match bonus once.

Casino Bonus USA

You can get up to $1,000 from Caesars with just 10x wagering.

Casino Bonus No Deposit

No deposit bonuses are exactly what they sound like: free money, no deposit required. Regulated online casinos in the US give out no deposit bonus money between $10 and $25 dollars. You can find most of the bonuses in NJ, but all legal online casino states offer some form of no deposit bonus.

$25 – $30 Free Play Bonuses

Not many US online casinos offer more than $25 as free money bonus. Therefore, the bonus cash you can receive from the best USA online casinos is even more valuable. The bonus amount can be used on slots, table games, or even bingo.

  1. Unibet Casino PA ($30)
  2. BetMGM ($25)
  3. Pala Casino ($25)
  4. Scores Casino ($25)

$20 No Deposit Bonus

Although $20 is more cautious than $25, it’s equally rare to find this offer at online casino operators in the US, as $20 free no deposit bonuses are limited to only two casinos, one of which only operates in New Jersey.

  1. Borgata Online Casino
  2. 888Casino

$10 No Deposit Casino Bonus

Most online casino offers only give you $10 free play bonuses. These bonuses can be credited in site credit or a no deposit bonus. Free cash is almost unheard of.

  1. Virgin Online Casino
  2. Tropicana
  3. Caesars Online Casino NJ
  4. Harrahs
  5. Hollywood Casino
  6. DraftKings Casino
  7. Unibet NJ

Best Bonus at a No Deposit Casino: BetMGM

BetMGM is the best no deposit casino in the US for several reasons. First, they have the biggest no deposit bonus ($25). They also have a huge deposit match (up to a $1,000) if you want to keep playing. Secondly, they are available in all the legal gambling states, and thirdly, their selection of online slots and table games is among the best in the US.

Free Spin Bonuses

Free Spins bonuses are still quite rare in the US compared to free bonus money and deposit casino bonuses. However, this online casino bonus is still available at some online casinos, either as no deposit free spins or free spins with wagering.

Golden Nugget Casino 200 free spins
Ocean Casino Resorts 50 free spins
Hard Rock Casino 50 free spins, no deposit required
Party Casino 25 no deposit free spins for Starburst
WynnBET 1,000 Free Spins on Divine Fortune

Best Bonus for Free Spins – Golden Nugget NJ

The best casino for free spins isn’t that hard to find. Golden Nugget gives you 200 free spins with only $30 deposit. You could also get a 1,000 spins from WynnBET Michigan, but you’d need to wager $1,000 first. The 50 free spins from Hard Rock and Ocean Casino fall somewhere in between, as they have no wagering whatsoever.

Casino Bonus Codes

Online casinos sometimes require bonus codes or promo codes for their deposit match or no deposit bonuses. This bonus code must be entered when registering a new account (for no deposit bonus codes) or when making a initial first deposit (for deposit bonuses). Before making a deposit, you should always check the terms and conditions to verify if the online casino requires a bonus code.

New Casino Bonus 2021

The US gambling industry is booming, but it’s more about online casinos moving to new states, rather than new online casino operators entering the market. However, there have been some new entrants lately. Furthermore, we’ll also update this space when new online casinos like Betway US release their welcome bonus.

Latest Casino Bonuses

While not many casinos have launched, some have opened in new states, or updated their bonus offers. For example, DraftKings updated their welcome offer to include $10 in site credits last December, and BetMGM opened it’s doors in PA. Furthermore, Michigan online casinos became legal in January 2021, giving Michiganers the opportunity to win real money from deposit offers in the Great Lakes State.

Best Casino Bonus in the US 2021

The best casino bonus in the US is the BetMGM $1,000 + $25. It is available in all four regulated states, and gives you the access to hundreds of casino games. Although the wagering requirements on the deposit match are on the high side, BetMGM has the only online casino bonus that combines a large welcome bonus with a big free play bonus.

Casino Bonus Terms & Conditions Explained

Casino bonuses come naturally with attached T&Cs. These requirements might be a bit confusing to new players, and people who visit established brick and mortar casinos as well. Therefore, we explain the most common t&cs that new players need to know when creating an account or making their first deposit are listed below.

Wagering Requirement

Casino sites don’t just hand out free bonuses or deposit matches to players as cashable bonuses. In order to cash out your bonus, you need to fulfill wagering requirements. This means that you have to wager through your bonus a set amount of times. Usually, the best bonuses are those with lowest wagering requirements.


Let’s say you receive a 100% up to $1,000 bonus from Caesars Online Casino. The bonus carries wagering requirements of 10x. This means that you must play slots with $10,000 before you money can be withdrawn as cashable bonuses. This may sound like a lot, but in the online casino world 10x is a very lenient wagering.

Game Contribution

Not all games are created equal when it comes to wagering requirements. Online slot games usually contribute 100% but if you play table games or video poker with high RTP (return-to-player), they might only contribute 20% of the stake towards the wagering requirements. Below you can find a table with the wagering requirements for real money games at one online casino.

Game Wagering Contribution
Slot Games 100%
Jackpot Slots 50%
Video Poker 25%
Table Games 25%

Restricted Games

In addittion to game contributions, many gambling sites restrict certain games and slot machines from being used for the bonus wagering because of their high RTP. Playing these specific games, which often include progressive jackpots, with bonus money is considered bonus abuse. Therefore, always check the fine print for restricted slots.

Minimum Deposit

Min deposit is the amount that you need to deposit to qualify for the bonus. For some casinos, the amount can be as high as $30 so casual players need to take care when taking advantage of casino deposit promotions.

Max Bonus

Maximum bonus describes the maximum bonus funds available with a single deposit. For example, DraftKings gives new players a 100% up to $1,500 bonus. This means that if you deposit $1,000, you’ll receive $1,000 extra. However, if you deposit $2,000, you’ll still only receive $1,500, as that’s the max bonus.
