About Us
US Online Casinos is a research-led comparison site covering online casinos available to players in the United States. We spend most of our time on the part of a casino offer that readers find hardest to check for themselves: what a free spins promotion is actually worth once the wagering requirement, maximum bet rule, expiry date and cashout cap are applied. This page explains who produces that research, how the rankings on cbcflooring.com are put together, how the site is funded, and where our findings stop being useful.
Why this site leads with free spins
Free spins are the most advertised and least understood casino promotion in the US market. A headline like "50 Free Spins" tells you almost nothing on its own. What decides whether the offer is worth taking is the surrounding detail: which slot the spins are locked to, the value per spin, how many times any resulting balance must be wagered, how long you have, and whether winnings are capped before you can withdraw them.
So our reviews start there. When we look at an operator, the first questions are practical ones — is a deposit required to trigger the spins, what is the minimum, does the spin value count toward the wagering calculation, and does the casino publish those terms where a reader can find them without digging through an archived promotions page. Sites that bury those answers get marked down, regardless of how large the headline number is.
How this site makes money
US Online Casinos earns commission when a reader signs up with some of the casinos listed here. That is how the research is paid for, and you should factor it in when you read any comparison page, including ours.
Two things follow from that, and we hold to both. Commercial relationships do not buy a position in our rankings or an editorial rating. And an operator's drawbacks are published whether or not we have a commercial arrangement with them — every write-up on this site carries at least one genuine limitation, including for the site we rank first. If we cannot describe a downside, we do not have enough information to publish a review.
We also do not take payment to remove criticism, adjust a rating after publication, or delay coverage of a change in terms.
Who writes the reviews
Editorial work on this site is produced by Briana Winslow, who writes about casino bonus terms, payment processing and state gambling regulation for a US readership. Findings on this page were last fact-checked on Sep 19, 2026.
One thing we state plainly: we do not deposit, play or withdraw at the casinos we cover. Our work is desk research — reading published terms and conditions, promotional pages, payment and verification policies, licensing and ownership disclosures, and publicly available regulatory records. Where we describe a withdrawal time or a processing fee, we are reporting what the operator advertises, not a result we produced ourselves. Advertised speeds are frequently optimistic, and we say so wherever we quote one.
What we assess before an operator is ranked
- Bonus terms in full. Wagering multiple, whether it applies to the bonus alone or to deposit plus bonus, maximum bet while a bonus is active, expiry window, and any cap on what can be cashed out from bonus winnings.
- Free spins specifics. Eligible games, spin value, whether the spins are credited in batches, and how winnings from spins are treated in the wagering calculation.
- Money in and money out. Minimum deposit, minimum withdrawal, published payout timeframes, withdrawal limits per day, week or month, and any fee the operator discloses.
- Verification. What KYC documents are requested, at what point in the process, and whether source-of-funds checks are mentioned in the terms.
- Games and software. The breadth of the slot catalog, availability of table games and live dealer rooms, and whether RTP figures and providers are disclosed.
- Licensing and ownership. Who operates the site, under what authority, and what the reader can verify independently.
- Player protection. Deposit and loss limits, session reminders, self-exclusion tools and the visibility of support routes.
- Complaints handling. Whether a dispute process is published, and whether there is any route beyond the operator's own support desk.
Editorial ratings are our own scores against those criteria. They are not customer-review averages and should not be read as one.
Three of the operators we cover, and what our research turns up
The ranked cards above show current headline offers. Below is what the research behind three of those positions actually found — including the parts an advertisement leaves out.
Raging Bull — the largest advertised free spins package on our list
Raging Bull sits at the top with an editorial rating of 10.0 and an advertised 410% up to $10,000 plus 50 free spins. It is here because the offer combines a very high match percentage with a spins component, and because the bonus structure is documented rather than vague. For a reader specifically hunting free spins attached to a deposit match, it is the most substantial headline figure on the page.
The assessment that matters: a 410% match with a $10,000 ceiling is only reachable by depositing far more than most recreational players ever will, and the spins are a fixed 50 regardless of deposit size. Treat the percentage as the useful number and the ceiling as marketing. Check the current wagering multiple, maximum bet while the bonus is live, and any cashout cap on the page before you claim — these are the figures that determine the real value, and they change.
Limitation: very large match bonuses almost always carry correspondingly heavy playthrough and a maximum-bet rule that voids winnings if breached, which makes this a poor fit for anyone who wants to clear a bonus quickly or bet at any size they choose.
Magician Bet — a no-wagering structure, which is rare
Magician Bet is rated 9.9 and advertises 101% with no wagering. It earns its place because no-wagering offers remove the single biggest reason bonus money never converts into a withdrawal. If playthrough terms are what put you off casino promotions, this is the structurally different option on our list.
What to weigh: no-wagering bonuses are almost never generous in size, because the operator has no playthrough to protect it. A 101% match is modest next to the triple-digit offers elsewhere on this page, and that trade-off is the entire point. Confirm what "no wagering" covers in the terms — some operators apply it to the bonus funds but still attach a withdrawal cap or a minimum deposit tier.
Limitation: the headline offer is not a free spins package, so readers arriving here specifically for spins will find less on the table than at the higher-match operators, and a modest match limit puts a low ceiling on the total value available.
Slots of Vegas — free spins tied to a named slot
Slots of Vegas carries a 9.6 rating and advertises a 375% bonus plus 50 free spins on Cash Chaser. It is included because the spins are tied to a specifically named game, which is more transparent than an unspecified "selected slots" allocation — you know in advance what you are playing.
The flip side is exactly that: the spins have no value to you if you do not want to play that title, and spin winnings from game-locked offers are commonly subject to their own wagering multiple separate from the deposit match. Check the per-spin value too, since 50 spins at a low denomination can amount to a small sum in real terms.
Limitation: game-locked spins restrict your choice, and a 375% match sits behind the same kind of playthrough and maximum-bet conditions as any large deposit bonus. Availability also varies by state, which is true across the board here.

Every offer above requires a qualifying deposit or purchase unless the operator's terms state otherwise, and all are subject to that operator's wagering, expiry and cashout conditions. Always read the current terms on the casino's own page — promotions change without notice, and our snapshot is dated.
How the money side works, and what we check
Cost of entry is the minimum deposit, and it is usually the smallest number on a promotions page. The expensive part is the playthrough: a 40x wagering requirement on a $100 bonus means $4,000 in qualifying bets before a withdrawal is possible, and games contribute at different rates — slots often at 100%, blackjack and roulette at a fraction of that, or not at all.
On the payment side, we look at what US players can realistically use. Debit cards are the most widely accepted deposit route; credit cards are accepted by some operators but may be treated as a cash advance by your card issuer, with its own fee. Bank transfers and ACH are common for larger amounts and slower to clear. E-wallets are offered by some sites, and PayPal availability at US online casinos is limited and state-dependent rather than universal. Crypto appears at some operators — Bets.FM quotes its bonus ceiling in BTC, which tells you where its payment rails sit.
Withdrawals are where friction concentrates. Expect a minimum withdrawal amount, a per-period limit, an identity check before the first payout, and a processing window that begins only after approval. We report published timeframes and flag when an operator does not publish one at all. We never promise a payout will arrive on schedule.
What the casinos we cover actually offer
- Slots. The bulk of every catalog, and the only category most free spins offers apply to. Volatility and RTP vary widely between titles; a high-volatility slot can burn through a bonus fast.
- Progressive jackpots. Pooled prizes that grow across players. Frequently excluded from bonus play or contributing nothing toward wagering.
- Table games. Blackjack, roulette and baccarat in RNG form. Lower contribution rates to wagering requirements are the norm.
- Live dealer. Streamed tables with human croupiers. Often excluded from welcome bonuses entirely.
- Sweepstakes formats. Some operators here, including Zumba Cards and Amazon Jackpots, use sweeps coins rather than direct cash wagering. The rules around redemption differ substantially from a cash casino and deserve reading before you buy a coin package.
- Mobile play. Most catalogs run in a mobile browser; dedicated apps are less common. We note which format an operator supports rather than assuming.
The other products these operators run
Several companies listed here are not casino-only businesses. BetUS operates sportsbook betting alongside its casino, and sportsbook promotions run on separate terms — a casino welcome bonus generally cannot be cleared on sports bets, and a sports free bet is not a free spin. Poker rooms, racebooks and virtual sports appear at some operators too. Where a site runs multiple verticals, bonus funds are usually walled off by product, and moving between wallets can forfeit a pending bonus. We treat those as distinct offers and review them on their own terms rather than folding them into a casino score.
Legal standing, eligibility and the honest limits of this site
Online gambling in the United States is regulated at state level, not federally. A handful of states license real-money online casinos and issue permits to named operators; in most others, online casino play is either unregulated or prohibited, and sweepstakes-style sites operate under a different legal theory again. Whether you may legally play, and which operators may legally serve you, depends on the state you are physically in at the time.
Two distinctions matter and are often blurred in casino advertising. Accepting US customers is not the same as being authorized to serve them — an offshore operator can do the first without the second. And "licensed" means nothing until you know which authority issued the licence and whether that authority has jurisdiction where you live. We report what an operator discloses about its licensing and ownership, and we tell you when it discloses nothing. We do not verify licences on your behalf, and we cannot tell you whether a given site is lawful in your state.
You must be 21 or older to use most US online casinos, though some jurisdictions set 18. You are responsible for checking your own state's rules before depositing. Winnings may be taxable. And no casino is completely safe — we will never describe one that way, guarantee a withdrawal, or suggest gambling is a way to make money or fix a financial problem.
If gambling has stopped being entertainment, our responsible gambling guide covers deposit and loss limits, self-exclusion, blocking software and the national support lines available in the US. Readers researching UK-facing options outside the GamStop scheme can find that covered on our Non GamStop casinos page, which is a separate market with separate rules.
Corrections, disputes and getting in touch
Terms change, promotions are withdrawn, and we get things wrong. If a figure on this site does not match what an operator currently publishes, tell us and we will check it and amend or remove it. We are also interested in reader accounts of withdrawal delays or disputed bonus voids — we cannot intervene on your behalf, and we are not a regulator or an arbitration service, but patterns in reader reports inform which operators we re-examine.

If you are comparing offers rather than checking our methods, the ranked list above is the place to start — read the operator's own terms alongside our notes, and treat the headline percentage as the least informative number on the page.
