BonusFinder Tip

Big doesn't always mean best. Smaller offers often come with easier wagering requirements and faster payouts.

Casino Bonus Types: What's Available in the U.S.

There are several types of casino welcome bonuses available at US online casinos. The best online casino bonus codes range from $40 to $2,500, and you can claim offers from multiple casinos in your state. Here is a quick overview of each type:

• Deposit Match Bonuses: The classic format. Casinos match your deposit up to a set amount.
• No Deposit Bonuses: Free funds on signup with no deposit required. Usually $10 to $50.
• Free Spins: Credited spins for use on specific slot games, ideal for slot fans.
• Cashback and Lossback Bonuses: Play with a safety net. Get a percentage of your losses refunded as site credit.
• Bet and Get Offers: Place a qualifying wager and receive a bonus reward in return.
• Social Casino Bonuses: Free coin packages and sweepstakes prizes for players in states where real-money casinos are not legal.

Welcome Bonuses at US Online Casinos

Welcome bonuses are the introductory offer you receive when you sign up at a new online casino. New players are typically offered a deposit match bonus, a no deposit bonus, or free spins. The size of the bonus and the wagering requirements attached to it vary from casino to casino. Here is a full breakdown of each type.

1. Deposit Match Bonuses

Deposit matches are the most common welcome bonus format at US online casinos. You can find large or small offers depending on how much you want to deposit and how you like to play. Some of the best deposit bonuses are state-specific, so check which ones are available where you are.

The main advantage of a deposit match is flexibility. You can play nearly any eligible game with your bonus funds (always check the T&Cs first), and you can choose exactly how much to deposit up to the cap.

Best Deposit Offer for New Players

Two casinos stand out for deposit bonuses: Caesars and FanDuel.

Caesars offers $1,000 in casino credits with a 15x playthrough requirement, plus a $10 no deposit bonus on registration. If you prefer value over volume, FanDuel requires just a $10 deposit to unlock 500 spins on Huff N'More Puff plus $40 in bonus funds, with spins requiring only 1x wagering before you can cash out winnings.

2. No Deposit Bonuses

No deposit bonuses are exactly what they sound like: free bonus funds credited to your account on signup, with no deposit required.

Regulated US casinos typically offer between $10 and $50 in no deposit funds. By combining offers across multiple casinos, you can access up to $200 in no deposit casino offers in total. New Jersey has the widest selection, but all legal online casino states offer at least one no deposit option.

Best No Deposit Casino

BetMGM is the top pick for no deposit bonuses in the US. They offer a $25 no deposit sign-up bonus along with a $1,000 deposit match for players who want to fund their account. BetMGM is also available across all legal gambling states, with a wide selection of slots, table games, and scratch card games.

Note: the current primary offer at BetMGM is the $2,500 deposit match plus 100 spins. The $25 no deposit bonus is a secondary offer.

3. Free Spins

Free spins bonuses are less common in the US than deposit matches or no deposit cash, but they are available either as standalone no deposit spins or as part of a deposit offer. Most free spins are tied to a specific game and rarely apply to newly released titles, though the available options are plentiful at the top casinos.

Top Free Spins Bonus

FanDuel offers the best free spins deal in the US: 500 spins on Huff N'More Puff with a $10 deposit, and winnings from those spins require just 1x wagering before cashout. Smaller no deposit spin offers are also available at casinos like Harrah's Online Casino.

4. Cashback and Lossback Bonuses

Cashback and lossback bonuses refund a portion of your losses as site credit over a set period. They are growing in popularity because they give you a safety net: you make a deposit, play your preferred games, and get compensated if you end the session at a loss.

These bonuses are particularly useful for table game and live dealer fans, since cashback typically applies to all game types rather than just slots. DraftKings Casino, for example, offers 100% lossback on losses within your first 24 hours of play, covering games including Basketball Roulette.

5. Bet and Get Offers

"Bet and Get" promotions have grown significantly in popularity. You place a qualifying initial deposit or wager, and the casino rewards you with a bonus in return, often with just 1x wagering on the reward. These offers are excellent for new players who want to maximize value from a small starting deposit.

Free chip bonuses work in a similar way. You convert a no deposit bonus into free chip credit and use it across available games. By combining offers, you can claim up to $75 in free chip no deposit bonuses across multiple sites.

6. Social Casino Bonuses

If you are in a state where real-money online casinos are not yet licensed, social casino bonuses are your best option. Social casinos operate on a sweepstakes model: they offer free coin packages on signup and through daily promotions, and you can use Sweeps Coins to play for prizes redeemable as cash.

Find a full list of social casinos in the USA on BonusFinder. Most accept players from nearly all states and offer generous welcome packages.

Top Social Casino Bonus

The best social casino welcome offers currently come from Wow Vegas, High 5 Casino, and Chanced.com. All three offer daily bonuses on top of their signup packages, and winnings from Sweeps Coins can be redeemed for real cash prizes.

Bonuses for Specific Games: Roulette and Live Dealer

Most casino bonuses are designed with slot players in mind. Roulette and live dealer games are often excluded or heavily restricted in terms of how much they contribute toward wagering requirements. Here is what to know before claiming a bonus if these are the games you prefer.

Best Roulette Bonuses

Roulette-specific bonuses are rare. Most deposit match bonuses set roulette's game contribution at between 10% and 20%, or exclude it entirely. That means clearing a standard wagering requirement with roulette play takes much longer than with slots.

The best format for roulette players is a cashback or lossback bonus, since these typically apply across all game types. DraftKings Casino's first-24-hour lossback offer covers roulette play at 100%, making it one of the strongest options for roulette fans.

Best Live Dealer Bonuses

Live dealer games are in a similar position. Most deposit match bonuses contribute 0% to 10% from live dealer play, and many operators exclude them from bonus wagering altogether.

Where live dealer players can benefit is through Bet and Get promotions and live dealer leaderboards. Several operators run campaigns where qualifying wagers on live blackjack or live roulette earn you casino credits, free spins, or cashback rewards. Live leaderboards award prizes based on points accumulated through live table play.

Best Alternative Casino Offer

For live dealer and roulette players, cashback offers are the most straightforward option since there is no complex wagering to navigate. Bally Casino stands out here: its cashback offer carries no wagering requirement, meaning any refunded amount is yours to keep or use as you choose.

Casino Bonus Codes

Most US online casinos offer welcome bonuses that require a promo code to activate. For example, you need the BetMGM bonus code FINDER2500 (or FINDERMI2500 in Michigan) when registering your account. Always check whether a code is required before completing signup, and make sure you meet the minimum qualifying deposit.

How to Use a Casino Promo Code

Entering a promo code is straightforward. When you register a new account, look for a designated bonus code field during the signup process. Enter the code exactly as shown, including any capital letters, before completing registration. Some casinos allow you to enter a code at the cashier when making your first deposit instead. If you miss the step, contact customer support before you deposit as codes cannot always be applied retroactively.

How to Choose the Best Casino Bonus for You

The best casino bonus on paper is not always the best one for how you play. Here are the steps to finding the right fit:

1. Decide what you want from the bonus: Are you after the biggest dollar amount? Free spins for slots? A safety net through cashback? Or the lowest wagering requirement? Identifying your priority narrows your options quickly.
2. Check the wagering requirement: A $2,500 bonus with 30x wagering requires $75,000 in bets before you can withdraw. A $500 bonus with 5x wagering requires only $2,500. Lower wagering almost always means better real-world value.
3. Check which games count toward wagering: If you prefer table games or live dealer, confirm they are not excluded or heavily restricted in the T&Cs before claiming a deposit match bonus.
4. Check the time limit: Make sure you can realistically complete the wagering requirement within the allowed window, which typically ranges from 7 to 30 days.

BonusFinder Tip

You can claim bonuses at multiple casinos in your state. There is no rule against holding accounts at more than one licensed operator.

How to Claim a Casino Bonus: Step by Step

1. Choose a casino from our list: Select a licensed operator available in your state. Check the bonus offer, wagering requirement, and any promo code needed before proceeding.
2. Create your account: Register with your personal details including name, address, date of birth, and the last four digits of your SSN for identity verification. Enter any promo code in the required field during signup.
3. Make a qualifying deposit: Deposit at least the minimum qualifying amount to trigger the bonus. If you are claiming a no deposit bonus or free spins, the funds are credited automatically after signup or on first login.
4. Start playing and meet the wagering requirement: Use your bonus funds on eligible games. Track your progress toward the wagering requirement in your account. Once complete, your winnings become withdrawable.

No Wagering Casinos

No wagering casinos are rare in the US, but low-wagering options exist and are worth seeking out. DraftKings Casino is one example: its lossback offer is straightforward with no complex playthrough attached to the refunded amount. You can also browse our guide to free spins with no wagering requirements for the best currently available options in the United States.

How to Calculate Casino Bonuses

Working out how much bonus value you are getting is straightforward once you know the formula for each bonus type.

1. No Deposit Bonus: No calculation needed. Complete the required signup steps and the bonus is credited automatically. What you see is what you get.
2. Deposit Match Bonus: Your deposit is matched by a set percentage up to a maximum cap. Example: a 100% match up to $500 on a $200 deposit gives you $200 + $200 = $400 total. A 125% match on the same deposit gives you $200 + $250 = $450. You cannot exceed the stated cap regardless of how much you deposit.
3. Cashback and Lossback Bonuses: Your losses over the qualifying period are calculated and refunded as a percentage. Example: you deposit $500, play through it, and finish with $300. Your net loss is $200. A 100% lossback offer returns all $200 as site credit. If you finish up, no cashback is triggered since there are no losses to refund.

Casino Bonus Terms and Conditions Explained

Every casino bonus comes with attached terms and conditions. Reading these before claiming an offer can save you a lot of frustration later. Below is a plain-language explanation of the most important T&C components you will encounter.

Wagering Requirements

Wagering requirements (also called playthrough requirements) determine how many times you must bet your bonus funds before any winnings become withdrawable. A casino does not simply hand out free cash: the requirement ensures you play before you cash out.

US casinos are considerably more player-friendly than their European counterparts. Typical wagering requirements in the US sit around 15x for slots. In the UK or Europe, requirements of 35x to 70x are standard.

The best value comes from low wagering online casinos, so this figure is always worth checking before you claim.

Practical Example

You claim a 100% match up to $1,000 at Borgata and deposit $1,000, giving you $1,000 in bonus funds. With a 15x wagering requirement, you need to wager $15,000 in total before you can withdraw. While that sounds large, at standard slot bet sizes it is cleared relatively quickly and remains one of the most lenient requirements available in the US market.

Game Contribution Rates

Not all games count equally toward your wagering requirement. Slots typically contribute 100%, meaning every dollar wagered on slots counts in full. Games with high RTP values, such as video poker or progressive jackpots, often contribute at a reduced rate. Live dealer games frequently contribute 0%.

Check the contribution table before deciding which games to play while clearing a bonus. The safest approach is to play eligible slots until the wagering requirement is met, then switch to your preferred games.

Game Restrictions

Some games are excluded from bonus play entirely, regardless of their contribution rate. Progressive jackpot slots, online lottery games, real money keno, and live dealer titles are the most commonly restricted categories.

Always check the fine print for the specific restricted game list before you start playing with bonus funds. Our recommended casinos allow bonus play across a wide range of eligible games.

Minimum Deposit Amount

The minimum deposit is the smallest amount you can deposit to qualify for the bonus. This varies by offer: some casinos accept as little as $5, while others set a $25 or $30 threshold. The qualifying deposit amount is always listed in the offer T&Cs and should never be listed in ambiguous terms.

Maximum Bonus Cap

The maximum bonus cap is the highest dollar amount a casino will award through a single offer, regardless of how much you deposit above that threshold. For example, a 100% match up to $1,000 means depositing $1,000 returns $1,000 in bonus funds, but depositing $2,000 still returns only $1,000 since that is the cap. The bonus percentage tells you the exact amount to deposit to maximize the offer.

Wagering Time Limits

Most casino bonuses carry an expiry date. Once you claim a bonus, you have a fixed window, typically 7 to 30 days, to complete the wagering requirement. Bonus funds not wagered through before the deadline are forfeited.

The time limit sounds restrictive, but at typical online slot bet speeds it passes faster than you might expect. Plan which games you will use to clear the bonus before you claim.

Maximum Bet Rules

While a game may allow bets up to $100 per spin, the bonus T&Cs often impose a lower limit, typically $5 to $10 per bet, while wagering through bonus funds. Exceeding the maximum bet can void your bonus and any associated winnings. Always check this figure before playing at higher stakes.

Casino Rewards Programs and Ongoing Promotions

Welcome bonuses are just the starting point. Loyalty programs and VIP schemes reward you for continued play with ongoing perks including monthly bonuses, exclusive promotions, and accelerated cashback rates.

The most well-known programs in the US are Caesars Rewards and MGM Rewards. Other strong options include Dynasty Rewards and Wynn Rewards. Each scheme works differently in terms of how points are earned and redeemed, so it is worth comparing them if you plan to play regularly at one casino.

Beyond loyalty programs, most operators run regular promotions for existing players: reload bonuses, free spin drops, tournament entry, and cashback deals. For example, wagering $25 on a specific game may earn you bonus spins on a new title. Unlike welcome bonuses, many of these promotions can be claimed repeatedly.

Check the Promotions page on your chosen casino regularly to stay up to date with active offers. New deals are added frequently, particularly around major sporting events and game launches.
