Contact Us
This page explains how to get in touch with the editorial team behind Online Casino Sites, what kind of questions we can realistically answer, and — just as importantly — which questions need to go to the casino itself or to a regulator instead of us. Most messages we receive fall into one of a few categories, so it is worth reading the routing guide below before you write. It usually gets you an answer faster.
We are a research and comparison publisher covering US online casinos. We do not operate a casino, we cannot access your player account, we cannot see your balance, and we cannot release a withdrawal or reverse a bonus forfeiture. If your issue is with an account, the operator has to fix it. What we can do is explain how a term works, point you to the right complaints channel, and correct anything on this site that is wrong or out of date.
Write to us about these things
- Corrections. If a bonus figure, wagering requirement, expiry window or state-availability note on nanomaterialscompany.com looks wrong, tell us which page and what you saw. Include a screenshot or the exact terms text if you have it.
- Terms we have not explained clearly. Free spins no deposit offers, playthrough maths, maximum bonus bet caps, cashout ceilings — if a guide left you guessing, that is a content problem on our side and we want to know.
- Editorial questions. How we rank, why one site sits above another, why an operator is or is not covered.
- Press and partnership enquiries. Including operators who want to be reviewed. Being reviewed is not the same as being ranked well, and it is not for sale.
- Accessibility problems. Pages that break on a phone, text that does not scale, anything that stops you reading the content.
Things we cannot do, and where to go instead
| Your issue | Who actually handles it |
|---|---|
| Withdrawal delayed or declined | The casino's support team first, in writing. If unresolved, escalate to the regulator that licenses the operator in your state. |
| Identity verification (KYC) documents rejected | The operator's verification or compliance team. They set the document standards, not us. |
| Bonus or free spins winnings voided | The operator, citing the specific term you believe was applied incorrectly. Keep the original promotion terms. |
| You want an account closed or self-excluded | The operator's responsible gambling settings, plus any state self-exclusion program you are eligible for. Our responsible gambling guide covers the tools available. |
| Payment shows as taken but no credit | The casino, then your bank or card issuer if the operator cannot trace it. |
| Site availability in your state | Your state gaming regulator publishes the list of authorized operators. That list, not an advert, is the authority. |
When you contact an operator, put it in writing and keep a copy. Note the date, the amount, the promotion name, and the exact clause in dispute. Most licensed operators publish a formal complaints procedure with a stated response window; if they do not resolve it within that window, that documentation is what a regulator or alternative dispute resolution body will ask for.
Where commercial relationships sit
Online Casino Sites earns commission when a reader signs up with some of the casinos listed on this site. That funds the research. It does not buy a ranking, a rating or a favourable write-up, and we do not remove a limitation from a review because a brand asked. If you think a page reads like an advert rather than an assessment, that is a fair thing to raise with us directly — we would rather hear it than not.
Advertised bonus figures throughout the site are the operator's own marketing claims as we recorded them. They change without notice. Editorial ratings are ours and are not customer review scores. Anything time-sensitive on this page was last checked Sep 25, 2026.
Offers readers ask about most
A large share of the mail we get is about headline bonus numbers and the conditions buried under them — particularly free spins attached to a deposit match. Here is how the top-ranked offers on this site actually read, so you can see what a question about them usually turns out to be.
Raging Bull — 410% up to $10,000 + 50 Free Spins
This one sits at the top of our list and draws the most correspondence, almost entirely because of the size of the number. Rated 10.0 editorially. The percentage and the $10,000 ceiling are the advertised maximum, not what an average deposit produces — a 410% match only reaches $10,000 if you fund the account with a large sum, and the 50 free spins are typically tied to named games with their own value cap. The limitation worth stating plainly: high-percentage matches of this shape almost always carry heavy playthrough and a maximum bet per spin while bonus funds are live. Break the bet cap and winnings can be voided even though the deposit was genuine. Read the playthrough multiplier and the max-bet clause before the headline percentage.
Magician Bet — 101% No Wagering
Included because it is the structural opposite of the offers around it. Rated 9.7. A no-wagering match means the bonus, if it credits as advertised, is not locked behind a playthrough multiplier — which removes the single most common cause of the disputes readers write to us about. The trade-off is the size: 101% is modest next to a 400% or 600% headline, and no-wagering promotions usually compensate with a tighter maximum bonus amount, a shorter validity window, or game restrictions on where the funds can be used. Confirm the cap and the expiry date before treating it as the easier option. Easier is not the same as larger.
Slots of Vegas — 375% Bonus + 50 Free Spins on Cash Chaser
Rated 9.7, and on this page because the free spins are pinned to one named title rather than floated across a library. That is useful clarity — you know exactly where the spins run — but it is also the constraint. Spins locked to a single game cannot be moved to something you prefer, the per-spin value is set by the operator rather than by you, and winnings from spins frequently sit under a separate cashout limit from the deposit match. Two sets of terms, in other words, not one. Check whether the spins expire before the bonus does; they often do.
Uptown Aces — 600% For New Players
The largest advertised multiplier in the list, rated 9.7, which is precisely why it belongs in a discussion about reading terms. A 600% match is new-player only, so it credits once and only on a qualifying first deposit; a deposit made with a method excluded from promotions, or below the stated minimum, generally does not trigger it. The limitation: the bigger the multiplier, the more likely the offer carries a cashout ceiling expressed as a multiple of the deposit. You can clear the wagering in full and still be paid less than your balance suggests. The ceiling matters more than the percentage.
Side by side on the terms that decide it
| Casino | Advertised offer | Editorial rating | What to check first |
|---|---|---|---|
| Raging Bull | 410% up to $10,000 + 50 Free Spins | 10.0 | Playthrough multiplier and max bet per spin |
| Magician Bet | 101% No Wagering | 9.7 | Maximum bonus amount and validity window |
| Slots of Vegas | 375% + 50 Free Spins on Cash Chaser | 9.7 | Separate spin expiry and spin winnings cap |
| Uptown Aces | 600% For New Players | 9.7 | Qualifying deposit method and cashout ceiling |
| Card Crush | Instant Welcome Reward: 2 Mystery Coins & 5 Cards | 9.3 | What the coins and cards convert to |
| Zumba Cards | 250% Deposit Bonus up to 250 SC | 9.2 | Sweeps-style currency and redemption rules |
| BetUS | 200% up to $4,000 for New Players | 9.1 | Rollover across casino and sportsbook |
| Amazon Jackpots | 4 Posters + 40 Free SC + Bonus Wheel for $20 | 9.1 | The $20 purchase requirement |
| Slots and Casino | 500% up to $2,500 x3 | 9.0 | Whether all three tranches must be claimed in sequence |
| Bets.FM | 225% up to 1 BTC + 225 Free Spins | 8.7 | Crypto denomination and conversion at withdrawal |
Note the Amazon Jackpots entry in particular: it requires a $20 purchase, so it is a paid package, not a giveaway, and we describe it that way. The same applies to any offer described as "free" that needs a deposit first.
Money questions we get asked before signing up
Costs and timings are set by each operator, so verify them on the cashier page rather than taking a general figure as gospel. Broadly, the things to establish before you fund an account in the US:
- Minimum deposit. Often lower than the amount needed to trigger a headline match. Depositing the minimum can leave you outside the promotion entirely.
- Accepted methods. Debit cards are the most widely accepted; credit card acceptance varies by issuer and some US banks decline gambling transactions outright. ACH bank transfer, wire and e-wallets appear at many sites, and PayPal availability is limited to certain state-regulated operators. Crypto features at sites such as Bets.FM, where the balance is denominated in the coin rather than dollars.
- Fees. Deposits are commonly fee-free; withdrawals may carry a flat charge, and card issuers can apply their own cash-advance treatment.
- Minimum and maximum withdrawal. Both matter. A weekly or monthly payout cap can stretch a large win over several cycles.
- Withdrawal timing. Expect a pending or review period before processing begins, then the banking transit time on top. Advertised speeds are the operator's claim, not a tested result.
- Verification. KYC is standard and legitimate. ID, proof of address, and sometimes source-of-funds documentation for larger amounts. Uploading documents early usually shortens the first payout, and a name mismatch between the account and the payment method is the most common cause of a rejected withdrawal.
What these sites actually offer
If you are writing to ask whether a site has the kind of game you want, the categories break down consistently. Slots make up the bulk of most libraries, ranging from low-volatility titles that pay small and often to high-volatility games that swing hard, with RTP percentages published per title and outcomes driven by a random number generator. Progressive jackpots pool across players and sometimes across operators; the top prize is rare by design. Table games cover blackjack, roulette and baccarat in digital form, usually with multiple rule variants that change the house edge. Live dealer rooms stream a human dealer in real time with table limits set per room. Sweepstakes-style sites such as Zumba Cards and Amazon Jackpots use a virtual currency model — SC and coin packages — which works differently from a dollar-denominated casino balance, particularly at redemption. Mobile play is browser-based at most operators, with native apps at some; the game selection on mobile is occasionally narrower than on desktop.
The other products these brands run
Several operators on this list are not casino-only. BetUS pairs its casino with a sportsbook and racebook, which matters because a welcome bonus may require rollover across both, and the qualifying-odds rules on sports bets are different from slot playthrough. Bets.FM operates in a crypto-denominated environment covering more than casino games. Card Crush, Zumba Cards and Amazon Jackpots sit in the sweepstakes and social gaming space rather than the dollar-wagering one. If you contact us about a bonus, tell us which product you were using — the terms are rarely shared between them.
Eligibility and regulation in the US
You must be 21 or over to play at most US online casinos, and 18 or over at certain sweepstakes operators. Online casino gaming is regulated state by state, not federally. A handful of states license real-money online casinos and publish a register of authorized operators; sports betting is legal in many more states than casino gaming is. Sweepstakes and social casino models operate under a different legal framework again and are not available in every state. Geolocation checks apply at licensed sites and will block play from outside a permitted state, and an operator accepting a sign-up is not the same as that operator being authorized to serve your state — check your regulator's list, not the marketing page. Our editorial approach and who writes here explains how we handle availability claims, and the site terms set out how we present operator information.
How we assess the sites we cover
Ratings come from documented research, not from play sessions — we do not deposit, wager or withdraw, and we do not claim to. We read published promotion terms, cashier pages, licensing statements and complaints procedures, and we record what we find with a date. Where something cannot be verified, we say so rather than filling the gap. Commission plays no part in position. If our reading of a term is wrong, send us the clause and we will correct the page.
Common questions about contacting us
How long does a reply take?
We read everything, and corrections get looked at first because an error affects every reader of that page. We cannot commit to a fixed response time, and we are not a 24-hour desk. Urgent account or payment problems should go straight to the operator, which does run one.
Can you get my withdrawal released?
No. We have no access to any casino's systems and no authority over payouts. What we can do is explain the term being applied and tell you which regulator or dispute body covers a licensed operator in your state.
Will you review a casino if I suggest it?
Possibly. Reader suggestions do influence what we look at next. Being added to the site does not mean a positive write-up, and we will not exclude a limitation because a brand or a reader dislikes it.
I think a bonus term on your site is wrong. What do you need?
The page, the specific figure you are disputing, and ideally the operator's current terms text or a screenshot with the date visible. Promotions change often enough that a discrepancy is more likely to be a stale entry than a disagreement.
Can you help me stop gambling?
Not directly, but we can point you to the tools that do: deposit and loss limits, cooling-off periods, operator self-exclusion, state self-exclusion programs and blocking software. Start with our player protection resources. If money or gambling is causing you harm, a support organisation will be more use than any comparison site, including this one.
Do you handle affiliate or media enquiries here too?
Yes, same channel. Mark the subject clearly so it is routed correctly. Commercial conversations are kept separate from editorial decisions, and we will say so in writing if asked.
Before you send your message
Include the page you were reading, the casino involved, the exact wording of the term in question and any dates or amounts. Vague messages take several rounds to resolve; specific ones often take one. If the question is really about whether a particular free spins no deposit or deposit-match offer is worth claiming, check the wagering multiplier, the maximum bet allowed while the bonus is active, the expiry date and the cashout ceiling first — nine times out of ten the answer is sitting in one of those four terms.
And if the answer genuinely is not there, write to us. Gaps in our coverage are the most useful thing a reader can send.
