Legal 100% First Deposit Bonus Casino Offers

The listed welcome bonuses apply a 100% match rate to your deposit, starting from a maximum cap of $250 up to $2,000. If you are a high roller, you should go for the highest value, but low rollers should look at the terms of each offer and go for the one with the least wagering requirements that are easier to cash out.

An important note relates to offshore online casinos, operators without an official license to operate in the USA. Such sites accept players from all states, unlike the above casinos that accept players where online gambling is legal, and operate illegally without regulations. Their offers might seem enticing, but the reality is they don’t pay out players, and their terms are unfair and predatory.

Anyone over 21 in New Jersey, Pennsylvania, Michigan, Connecticut, Delaware, and West Virginia can find an offer for their state in the online casinos above. Wondering which is the best or how to choose one of the above? Continue below for some helpful tips to get the best value for your buck.

Best Value 100% Casino Bonus for New Players – DraftKings

$50 Free Play & $2,000 Bonus
  • Excellent mobile app
  • User-friendly design & games

Americans interested in gambling online must have heard of DraftKings Casino at least once. The site has operated as a daily fantasy sports site since 2012 and as an online casino and betting app since 2018.

The DraftKings Casino bonus code link provides the best welcome bonus for high rollers:

  • 100% deposit bonus up to $2,000; a $50 no deposit casino bonus will also be credited to your account after registration.

In terms of value, no other operator is coming close to DraftKings Casino. Deposit $2,000 the first time you use a DraftKings banking method, and your available balance will become $4,000.

DraftKings Casino Bonus

The offer applies to all DraftKings online slots and the DraftKings Rocket game, counting 100% towards meeting the applicable wagering requirements. Progressive jackpot slots, live dealer games, and table games like video roulette are either excluded or offer a lower weighting percentage towards turning your bonus funds into real cash.

Other 100% casino match welcome bonus codes that are almost as good as the one from DraftKings are:

Not every player will deposit $1,000 or $2,000 to get started with a USA online casino. That’s reasonable, but most players are unaware that there are better offers for those not interested in massive welcome bonus offers.

Our research indicated that BetRivers Casino and SugarHouse Casino, both owned by Rush Street Interactive and operating in different US states, have the best 100% welcome bonus for those looking for smaller offers with the lowest wagering requirements:

BetRivers Casino Bonus

Any new player who deposits between $10 and $250 will see their balance double. Play the best BetRivers Casino slots or the top slots on SugarHouse Casino to turn the free money into real cashable funds without struggling too much. For the maximum bonus amount, you would need to wager $250, and all remaining funds would become available to withdraw in your bank account. No maximum winning cap applies, and the offer must be played through within 30 days.

The BetRivers welcome bonus might be impressive, but it is far from the only 100% match offers for new players with below 5 – 10x wagering requirements. The following are other player-friendly welcome casino bonus codes at licensed operators:

Use the codes indicated on the banners and perform a qualifying deposit to receive your bonus. Players can opt-in for more than one 100% match bonus, so bookmark this page for the next time you will be playing online casino games.

How 100% Casino Match Offers Work

Players looking for welcome casino bonuses are often new to online gambling and therefore unsure how to make the most of what USA gambling sites offer. Don’t sweat over it, though, as we will clearly indicate how to claim a 100% match bonus as a new player at the casino. Follow the below steps, and you will see your available balance double in no time:

  1. Select one of the casino apps listed. Ensure they are available in your state and whether they highlight a casino bonus code. For details, you can read our reviews of each 100% match online casino.
  2. After you click on the banners of your preferred online casino, you will be redirected to their sites. This will happen indifferently to how you decide to play since each has an online website and a casino app. In this case, you will be claiming iPhone casino bonuses or Android casino bonuses. The process is the same indifferently.
  3. When you are redirected, click on the sign up or registration button. Next, you will be required to provide a few personal and address details, such as username, email, password, zip code, and last four digits of your SSN.
  4. Before you complete the process, look out for any bonus code field. You can copy the code or type it, if provided, at this stage. In other instances, the casinos require you to use our links to qualify.
  5. Verify your account through the email link. Then, you will be redirected to the casino cashier page. Select the banking option that suits your needs, and make a minimum deposit. Some operators will ask for the bonus code at this stage. Once your first deposit is accepted, the bonus funds will be instantly credited.

Now, assuming you deposited $1,000 at the 100% bonus casino, your balance will look like this:

  • $1,000 real money balance
  • $1,000 bonus money

Then, depending on the requirements, you will need to play casino games. Your bonus cash balance will be slowly converted – but not available to withdraw until the total amount is played through. When the rollover requirements are met, your bonus and cash balance will be the same.

An important distinction to be made has to do with how 100% match bonus wagering requirements work. If these apply on the bonus balance only, this amount will be played through as you bet on casino games. On the other hand, when the wagering requirements apply on both the deposit and the bonus amount – you must playthrough the combined amount a set number of times.

When wagering requirements apply on D + B, they are often too high and not worth opting in. For an idea, if you claim a $1,000 bonus, through your first $1,000 deposit, with 40x wagering requirements – the total amount you would need to wager would be $80,000! That would require considerable time and luck for a decent sum to then be cashable.

Other Casino Bonuses for New Players

A 100% deposit bonus is the predominant way of how online casinos welcome new players. They are straightforward and highly rewarding, doing a great job of attracting new players. No welcome bonus below 100% is available at licensed US casino sites, but some match your first deposit at a 120% rate.

Offshore gambling sites might go as high as 200% match or 300% match on your real money deposit. Still, you should not opt-in for these, as they are illegal and unsafe to play at.

Other welcome bonuses you might encounter include:

No deposit promo codes – site credit instantly available after registration, available at fixed values.

Cashback or risk-free day – any money wagered within a time frame is refunded up to a certain amount. These work similarly to 100% match offers but apply only to net losses.

Deposit bonus and free spins – some operators also hand out deposit free spins on top of a matched bonus. These can be anywhere from 120 free spins to 500 free spins, applying on selected on all casino slot games.

Refer a friend offers, casino reload bonus offers, and VIP offers are also available, but as special promotions for existing players.

100% Match Bonus Terms and Conditions

The primary way in which we differentiate between welcome bonuses is through their terms and conditions. All welcome promotions highlight some limitations, which are essential to read before opting for the bonus. These indicate any or all of the following:

Bonus value – the maximum amount you can win as a bonus

Match rate – at what percentage your first deposit will be boosted

Minimum deposit – the minimum required amount to qualify for the 100% bonus

Maximum win – some offers might come with a win limit, which you cannot exceed when playing with bonus funds

Wagering requirements – a vital term indicating how many times you must play your bonus to become cashable

Qualifying bets – the amount you can bet per round or spin when playing with bonus funds

Time limit – the period within which you must wager your bonus funds before they expire

Bonus code – the combination of letters and numbers that might be required to receive the offer

Legal terms – minimum age and states where the offer is valid

Game weighting – not all games are available to play with an active bonus or contribute the same towards the wagering requirements. Often, jackpot and live games are excluded.

The above might seem like a lot, but they aren’t. This is how they would look in practice:

The 100% deposit bonus up to $2,000 requires a minimum deposit of $10. New players over 21 in New Jersey and Pennsylvania can qualify. The maximum bet is $5 on slot machines only. Bonus funds expire after seven days, and the bonus is credited instantly when you enter the code GUSA. Blackjack and roulette contribute 25x towards the 20x wagering requirements.

Keep in mind that the terms at legal operators are fair and easy to satisfy, without any hidden catch in the fine print.

Legal States For 100% Casino First Deposit Offers

Welcome bonuses were only available at offshore operators up until 2018. When PASPA got overturned in 2018, each US state became free to regulate online casinos and sportsbooks. So far, New Jersey, Pennsylvania, Connecticut, Michigan, West Virginia, and Delaware are the only states where online casinos are legal. The above operators accept players from one of these states, so if you live or travel there – don’t miss out on the best 100% casino bonus offers. Alternatively, have a look at the no deposit sweepstakes casinos that work with cash prizes everywhere in America.

This guide has hopefully helped you understand how each first deposit match bonus works. We have tried to lay out everything from the steps to unlock each welcome promotion to turning your bonus money or free chips into winnings.

Gamblers looking to begin their journey should not miss out on 100 casino deposit bonus offers. These might be promotional stands many online casinos use to attract players, but they offer free cash that you shouldn’t miss.

FAQ

What are playthrough requirements?

The playthrough requirements, also known as wagering requirements or rollover conditions, are the most important term for online casino bonuses. Essentially, it indicates the number of times a deposit bonus must be wagered until bonus money becomes cashable winnings. It doesn’t apply just to a welcome package bonus but also to free chips, free spins, deposit bonus spins, a reload bonus or cashback bonus, and other promotions.

What games can I play with an active bonus offer?

Most promotions and online casino offers for new users apply to online slots. This is not just for deposit free spins but all other types of bonuses. Progressive jackpot slots and live games are always excluded unless the casino has introduced special promotions for these games only. Roulette, blackjack, craps, and other games are available to play with an active bonus offer but tend to contribute less towards the playthrough requirements.

Do I need a promo code for a welcome deposit bonus?

If the terms and conditions say so, a promo code during deposits will be required to receive any promotions. Our banners and reviews provide any required promo codes, but you can also check with the casino’s support team to be safe.

Which online casinos offers are the best in the USA? 

The best casinos bonus offer is hard to provide since each player has different requirements. If you want the best value on your deposits, then DraftKings has the best package bonus. In terms of value and playthrough requirements, BetRivers, SugarHouse, and FanDuel Casino are as good as things get for gamblers.
