Best Casino Bonuses Online: New, No Deposit & Welcome Offers

Casino bonuses are one of the easiest ways to get more out of your first deposit. They stretch your bankroll, give you more time at the games you actually want to play, and let you try a new casino before you commit to it fully.

On this page, we break down the top casino bonus offers at the best online casinos in the United States, by minimum deposit, wagering requirement, and the states where each one is live.

• These bonuses depend on what's available in your state. Change the state using the drop-down menu.
• If real money online casinos aren't available in your state, you'll see your next best option, whether that be choosing from a list of sweepstakes casinos (where you can still win real money) or a social casino where you cannot.

Every offer on this page is checked directly against the operator's own terms and conditions before it is listed, and we update the page regularly as offers, codes and state availability change. The page is written by Joss Wood, Casinos.com's casino bonus specialist, and fact-checked by the Casinos.com editorial team before publication.

Regulated Casino Bonuses

Sweepstakes Casino Bonuses

BetMGM runs on the MGM Resorts network, Bellagio, Aria, MGM Grand, Borgata, and every dollar you play earns MGM Rewards credit that works at those properties, not just online. It's the only regulated casino bonus on this list that doubles as a foot in the door to Vegas comps.

Code CASINOBONUS unlocks Deposit for up to 1,000 Bonus Spins - Take on the Wheel For More!, just a $10 minimum deposit, live in all four states.

DraftKings built its welcome offer around volume instead of a single lump sum: 1,000 Flex Spins, spread across 20 days, so you're getting a reason to come back daily instead of one big hit that's gone in an hour.

No code needed, and at a $5 minimum deposit, it's the easiest offer on this list to just go try.

FanDuel consistently posts the highest app-store rating of any regulated casino in the country, and it shows the second you open it: cleanest lobby, fastest live dealer streams, nothing buried.

The welcome package pairs 500 bonus spins with a $50 casino bonus for a $5 deposit ($10 in West Virginia), no digging through menus required to find it.

Caesars Palace Online Casino plugs straight into Caesars Rewards, the same loyalty network that spans 50-plus physical casinos across the US and Canada, so your online play earns Reward Credits redeemable at properties on the Strip, not just inside the app.

Code CASINOSLAUNCH adds a 100% deposit match up to $1,000 on top of a $10 registration bonus, $10 minimum deposit to get in.

BetRivers skips the deposit-match playbook most operators run and goes with a lossback instead, which tells you a lot about who built it: Rush Street Interactive runs physical Rivers Casino properties and designed iRush Rewards around getting something back even on a rough day.

Code CASINOBACK returns 24 hours of losses up to $500, $50 minimum deposit to qualify, at a 1x playthrough on the bonus money.

Golden Nugget pairs a Vegas and Atlantic City pedigree with one of the deepest slot libraries in the regulated market, and its Rewards program now runs through the same Dynasty Rewards system as DraftKings, so loyalty points stretch across both.

The welcome offer spreads 500 Flex Spins over 20 days, no code needed, just a $7 minimum deposit, the lowest entry point on this list.

Fanatics Casino leans on the same Fanatics ecosystem that already touches sports merch and sports betting, so a Fanatics account carries across casino, sportsbook, and the FanCash loyalty currency you may already be earning elsewhere in the app.

The welcome offer is spins-based rather than a deposit match: wager $10 and you get 1,000 Bonus Spins on 7's Fire Blitz Power 5 Jackpot Royale Express, paid out at 100 spins/day over 10 days. No promo code needed, $5 minimum deposit, live in MI, NJ, PA and WV.

bet365 built its global reputation on sports betting depth, and its US casino carries that same operational scale, deep game library, live dealer tables, fast cashier, backed by a brand that already runs regulated books across multiple states.

The welcome offer pairs a 100% deposit match up to $1,000 with up to 1,000 spins, no promo code required, $10 minimum deposit. Live in MI, NJ and PA; not currently available in WV.

PlayStar is one of the smaller names on this list, live in New Jersey only, but it's carved out a niche with frequent reload promos and a loyalty program built around its own in-house slot titles.

The welcome offer is a 100% deposit match up to $500 plus 500 extra spins, no promo code needed, $20 minimum deposit. PlayStar also runs a first-deposit lossback (100% of net losses back up to $200) as a separate promo, worth checking if the welcome match isn't the better fit for how you play.

Crown Coins has built its name on being the dependable one in a sweepstakes market full of flashy newcomers, with a five-tier VIP Club (Bronze through Emerald) that pays Coinback the higher you climb.

First purchase doubles your coins outright: 200% more, 1.5M Crown Coins plus 75 Sweeps Coins, no purchase necessary to play and no promo code needed.

Mega Bonanza stands out in the sweepstakes space for something most competitors skip entirely: real live dealer tables, roulette, blackjack, and game-show style play, not just slots.

The first-purchase offer is a 150% boost up to 600,000 Gold Coins plus 303 free Sweeps Coins, no purchase necessary and no code required.

Stake.us is the US sweepstakes arm of the Stake brand, the most recognized name in crypto casino gaming worldwide, and it brings that same crypto-first, instant-redemption DNA stateside along with Stake's in-house, provably fair Originals you won't find anywhere else.

The welcome offer leads with 250,000 Gold Coins plus $25 Stake Cash, no purchase necessary, unlocked with code CASINOSDOTCOM.

Lone Star leans into its Texas identity, from the frontier-themed lobby to its seven-tier VIP ladder, one of the deepest loyalty structures in the sweepstakes space, complete with a personal VIP host at the higher ranks.

The welcome offer is up to 500,000 Gold Coins, 105 free Sweeps Coins and 1,000 VIP Points, no purchase necessary and no code needed.

Extra spins bonuses give you a set number of spins on specific slot titles. Of the operators on this page, DraftKings and Golden Nugget both structure their welcome offer this way rather than as a straight deposit match.

A lossback bonus refunds your net losses over a defined window, usually your first 24 hours or first deposit, as bonus credit. If you finish that window ahead, the bonus never activates and you simply keep your winnings. BetRivers is the only operator on this page running this offer type.

Only two operators on this page currently run a standalone no-deposit promo alongside their main welcome offer.

If you get the details of one of the bonuses listed above, you can see how it works using our Wagering Calculator. Try a few out and see how each bonus is different.

A bonus's headline number rarely tells the whole story. A 200% match sounds bigger than a 100% match, but if the 200% offer caps out at $100 and carries a 30x wagering requirement, while the 100% offer goes up to $1,000 at 15x, the second offer is worth far more in practice.

Wagering requirements. This is the number of times you must wager the bonus amount before you can withdraw it or any winnings from it. A $50 bonus at 10x wagering means you need to place $500 in total bets on eligible games before that money converts to withdrawable cash. Lower is better: offers at 1x to 10x are realistic to clear in a normal session or two, while 30x-plus requirements take considerably longer and carry more variance risk along the way.

A note on terminology. Wagering requirement, playthrough requirement, rollover, and turnover requirement all mean the same thing: the amount you must bet before a bonus becomes withdrawable. We use "wagering requirement" throughout this page, but you'll see the other terms used interchangeably elsewhere.

What the wagering requirement applies to. Check whether the multiplier applies to the bonus amount alone or to the bonus plus your deposit combined, since the second version roughly doubles the total amount you need to wager. A 15x requirement on a $200 bonus means $3,000 in wagers; a 15x requirement on a $200 deposit plus $200 bonus means $6,000. This single distinction has a bigger effect on a bonus's real value than the headline multiplier does on its own.

Game contribution rates. Not every game counts equally toward a wagering requirement. Slots typically contribute 100%, while table games, live dealer, and video poker often contribute at a reduced rate (sometimes as low as 10-20%) or not at all. Always check the eligible games list before assuming your favorite table game will clear a bonus.

RTP (Return to Player). This is the theoretical percentage of all wagered money a game returns to players over the long run. A 96% RTP slot returns, on average, $96 for every $100 wagered over millions of spins. RTP has nothing to do with any single session, but it does affect how quickly a wagering requirement realistically clears: lower-RTP games burn through your balance faster for the same wagering progress.

Volatility. Volatility (or variance) describes how a game pays out, not how often it wins overall. Low-volatility games pay smaller wins more frequently, which tends to be gentler on a bankroll while clearing a wagering requirement. High-volatility games pay out less often but bigger when they hit, which can clear wagering faster if you get lucky, or burn through the bonus balance quickly if you don't.

Win caps and max cashout. Some bonuses, especially no-deposit offers, cap the total amount you can withdraw regardless of how much you actually win. A $10 no-deposit bonus with a $100 max cashout means any winnings above $100 are forfeited. Always check this figure before assuming a small bonus could turn into a large withdrawal.

Time limits. Nearly every bonus has an expiry window, commonly 7 to 30 days, in which the wagering requirement must be met. Miss the window and the unused bonus, and sometimes any winnings tied to it, are forfeited.

Sweepstakes bonuses are a little bit different. Smaller, but relative to the stakes and cost of play they offer real value. You don't get dollar figures at sweepstakes, you get coins. Two types of coins, usually gold coins and sweeps coins, but different casinos use slight variations of the terminology.

Gold coins turn into sweeps coins and sweeps coins turn into cash. That's the bit to remember.

Social casinos using the sweepstakes system don't standardize on any specific conversion rate from gold coins to sweeps coins. You have to look at the terms and conditions. There is a de facto standard for sweeps coins; one sweeps coin almost always has a value of $1.

Every casino wants to be different but there are only so many ways to package a promotion. These are the main types you'll see on this page.

A welcome bonus is the offer a casino extends to you the first time you deposit, almost always structured as a percentage match up to a set dollar amount (for example, a 100% match up to $500 turns a $500 deposit into $1,000 in playable funds). Welcome bonuses carry a wagering requirement and are the most common bonus type in the regulated US market.

Why claim a welcome bonus: it doubles (or more) your starting bankroll, giving you more sessions and more chances to hit a meaningful win before you've risked any additional money of your own.

A no deposit bonus is credited to your account, as either bonus cash or extra spins, just for registering and verifying your account, with no deposit required. These offers tend to be smaller in total value than welcome bonuses, and often carry a max cashout cap, but they let you test a casino's games and platform without any financial commitment at all.

Why claim a no deposit bonus: it's the only genuinely risk-free way to try an operator's games, software, and withdrawal process before deciding whether to deposit real money.

A promo code is a short alphanumeric string entered during registration or at the cashier to unlock a specific offer, sometimes an exclusive one not available to players who sign up without it. Missing the code, or entering it incorrectly, can mean receiving a smaller default offer instead, or no bonus at all.

Why claim with a promo code: it's frequently the only way to access an operator's best publicly available terms, since many casinos reserve their strongest welcome packages for tracked, code-specific signups.

Extra spins bonuses give you a fixed number of spins, usually on one or a small handful of specific slot titles, with each spin valued at a set amount (commonly $0.10 to $0.50 per spin). Increasingly, US operators are structuring these as no-wagering offers, where any winnings from the spins are paid directly as cash or low-wagering bonus credit rather than requiring a full playthrough.

Why claim an extra spins bonus: when the spins carry no wagering requirement on winnings, they're one of the more straightforward offers in the market, small, capped, but real extra plays on games you're already playing.

A cashback or lossback bonus refunds a percentage, sometimes up to 100%, of your net losses over a defined window (commonly your first 24 hours, first deposit, or a recurring weekly period). Unlike a deposit match, you only receive this bonus if you lose money during the window, making it a genuine safety net rather than a guaranteed bonus.

Why claim a cashback bonus: it removes some of the downside risk from your first session, since a rough start is partially refunded rather than simply lost.

A reload bonus works like a welcome bonus but is offered to existing players on a second or later deposit, rather than only on the first one. These are usually smaller than welcome offers and run on a recurring schedule (weekly or monthly), each with its own code and terms.

Why claim a reload bonus: it's the main way returning players keep getting bonus value after their welcome offer is used up, without having to open a new account.

1. Choose a verified offer. Use the comparison table above to pick a bonus that matches how you play, rather than just the biggest headline number.
2. Register an account. Sign up directly through our link to ensure any tracked promo code or exclusive terms apply correctly.
3. Verify your identity. US regulated casinos require age and identity verification (typically ID and address confirmation) before you can deposit or withdraw.
4. Enter any required promo code. Do this at registration or at the cashier before depositing, since codes usually cannot be applied retroactively.
5. Make your qualifying deposit. Check the minimum deposit required to trigger the bonus; depositing less than the minimum can forfeit the offer entirely.
6. Opt in if required. Some bonuses activate automatically, others require an explicit opt-in in your account or rewards section, check the terms for your specific offer.
7. Meet the wagering requirement. Track your progress in your account dashboard, and stick to eligible games that contribute at 100% wherever possible.
8. Withdraw your winnings. Once the wagering requirement is cleared and any time limit hasn't expired, your bonus winnings become withdrawable cash, subject to the operator's standard withdrawal process.

Do:

• Read the full terms before depositing, not just the headline offer
• Check which games contribute, and at what rate, toward the wagering requirement
• Track your bonus expiry date so you don't forfeit progress
• Confirm your state and the offer are matched, since many pages list offers by state
• Keep a copy of the promo code and terms until the bonus clears

Don't:

• Don't assume a bigger percentage match is automatically a better offer, check the wagering requirement and max cashout too
• Don't deposit more than the minimum needed for the bonus unless you intend to play with the extra funds regardless
• Don't play games excluded from wagering contribution and expect that play to count
• Don't let a no-deposit bonus's small size trick you into ignoring its win cap
• Don't chase losses to try to clear a wagering requirement faster than your bankroll allows

If gambling stops being fun, free, confidential help is available 24/7 from the National Council on Problem Gambling at 1-800-GAMBLER, and you can confirm any operator's license status directly with the Michigan Gaming Control Board license lookup or your own state's equivalent regulator.

The right casino bonus isn't the one with the biggest number on the button, it's the one whose terms match your deposit size, your favorite games, and how quickly you want to play through the requirement. Use the comparison table above to shortlist a few offers, run them through the wagering calculator, and read the full terms on the operator's site before you deposit.
