Contact Us — Questions, Corrections and Feedback

Email us at [email protected]. That address reaches the editorial team behind Online Casinos, and it is the right place for questions about a review, a correction to something we've published, a payout or bonus term you think we've described wrongly, or general feedback on the site. We read everything. We aim to reply to genuine enquiries within a couple of business days, though research-heavy questions can take longer.

One thing to be clear about up front: we are an independent comparison and research site, not a casino operator. We cannot see your account, release a withdrawal, unlock a bonus or overturn a verification decision. If your issue is with a specific operator, the section below on dispute routes and player support will get you further than we can.

What to email us about — and what to send instead to the operator

Send to us	Send to the casino (or a regulator)
A factual error in a review — wrong wagering multiple, outdated bonus, closed payment method	A pending withdrawal, a delayed payout or a missing deposit
A bonus offer listed here that no longer matches the operator's own terms page	KYC and identity verification requests, document rejections, source-of-funds queries
Questions about how we rank, rate or select the casinos on our top lists	Account closure, self-exclusion requests or deposit and loss limit changes
Partnership, advertising and commercial enquiries	Disputes over a voided win, a maximum bonus bet breach or a cashout cap
Your own experience with a listed casino — payout speed, support quality, friction at withdrawal	Anything that needs your account number, balance or personal documents

Please don't email us account numbers, copies of ID, card details or screenshots containing personal data. We have no way to act on them and no reason to hold them.

How we handle commercial relationships

Some links on this site are commercial. If you open an account through one, the publisher may earn a commission at no extra cost to you. That arrangement does not buy a position on a list, a rating or a favorable sentence in a review, and we will say so plainly if you ask. If you believe a page reads like an advert rather than research, tell us which page and which paragraph — that's a useful complaint and we'd rather hear it than not.

Corrections: what we need from you

Bonus terms, payout limits and state availability change without notice, and a page that was accurate when published can drift. Corrections are the most valuable mail we get. To turn one around quickly, include:

The page and the exact line you're querying.
What you believe the correct information is.
Where you saw it — the operator's terms page, cashier screen or support transcript is ideal.
The date you saw it, since offers are often rotated.

We verify against the operator's own published terms before changing anything, and we date time-sensitive findings. Where a question can't be resolved — an operator won't confirm a limit, or its terms contradict its marketing — we say that rather than guessing.

The casinos we're most often asked about

Reader mail clusters around a handful of the operators we list, usually about the size of the headline offer versus what it actually takes to clear it. Ratings below are our own editorial scores, not customer-review averages, and every offer named here is the operator's advertised promotion — always read its current terms on site before depositing, because the numbers move.

Raging Bull — the biggest advertised number, and the most questions

Raging Bull sits at the top of our list and carries our highest editorial rating (10.0), largely because its game library and promotional depth are wide even by the standards of this group. Its advertised welcome offer is 410% up to $10,000 plus 50 free spins, and that headline is exactly why our inbox fills up with it. A percentage that size is matched to a qualifying deposit, and the ceiling is theoretical for most players — reaching anything near $10,000 in bonus funds requires a deposit larger than most people make. Expect wagering requirements, maximum bet caps while a bonus is active, an expiry window and, on high-percentage offers of this type, a cap on how much of the bonus winnings can be cashed out.

Limitation: the gap between the advertised figure and realistic value is the widest on our list. If you dislike reading terms closely, this is not the offer to start with.

Magician Bet — the one that answers the wagering question

Magician Bet earns its 9.8 rating for a different reason: its advertised 101% no wagering promotion removes the single mechanic readers ask about most. No wagering means bonus winnings are not locked behind a playthrough multiple, which is rare and worth understanding. The trade-off is scale. A 101% match is modest next to the four-figure percentages elsewhere on this page, and "no wagering" does not mean "no conditions" — minimum deposits, qualifying game weightings, maximum stakes and time limits can all still apply.

Limitation: smaller headline value, and readers who chase big bonus balances will find it underwhelming.

Slots of Vegas — a targeted spins offer

Also rated 9.8, Slots of Vegas is on this page because its offer is specific rather than open-ended: 375% bonus plus 50 free spins on Cash Chaser. Tying spins to one named slot makes the value easier to calculate than a generic spins pool, and it tells you where the operator wants the volume. What it also means is that the spins are not portable — you cannot move them to a game with a higher return to player or a volatility profile you prefer. The percentage match will carry the usual playthrough and cashout conditions.

Limitation: the free spins are locked to a single title, so their worth depends entirely on whether you'd play that game anyway.

Uptown Aces and the rest of the list

Uptown Aces advertises 600% for new players at a 9.6 rating — the largest percentage on the page, with the same caveat that applies to every offer of this shape: the multiple is applied to a qualifying deposit and governed by wagering, bet caps and withdrawal limits. Card Crush (9.6) leads with an instant welcome reward of 2 mystery coins and 5 cards, and Zumba Cards (9.5) with 250% up to 250 SC — both denominated in site currency rather than dollars, which changes how you should read their value. BetUS (9.4) offers 200% up to $4,000, Amazon Jackpots (9.4) bundles 4 posters, 40 free SC and a bonus wheel for $20 — a paid entry, not a giveaway — Slots and Casino (9.3) runs 500% up to $2,500 across three deposits, and Bets.FM (9.0) advertises 225% up to 1 BTC plus 225 free spins, which is a crypto-denominated offer and will not suit anyone who wants to fund an account in dollars only.

Money questions we get asked constantly

We can explain how these mechanics generally work; we can't quote a figure an operator hasn't published. Where a specific limit matters to you, ask the casino's support team in writing before you deposit and keep the reply.

Minimum deposits. Most percentage bonuses have a qualifying minimum. Deposit below it and the bonus simply doesn't attach — a common and avoidable complaint.
Payment methods. Debit cards, credit cards (often declined for gambling by US issuers), ACH bank transfers, wire transfers, e-wallets and, at some sites, crypto. PayPal availability is patchy and depends on both the operator and your state. Check the cashier while logged in rather than trusting a marketing page.
Fees. Deposits are usually free; withdrawals may carry a processing fee, particularly on wire transfers or when you request more than one payout in a period.
Withdrawal timing. Two clocks run: internal review, then the payment rail. E-wallets are typically fastest, card refunds and ACH slower, checks and wires slowest. First withdrawals take longest because verification happens then.
Limits. Minimum withdrawal amounts, daily, weekly or monthly caps, and separate caps on winnings from a bonus. High-percentage welcome offers are the ones most likely to carry a cashout cap.
Verification. Expect ID, proof of address and proof of payment method. Larger balances can trigger source-of-funds checks. Uploading documents on day one, not at withdrawal, is the single best way to speed up a first payout.

What's actually on offer at these sites

Readers writing in about "highest payout" usually mean one of two different things — fast, unobstructed withdrawals, or games with a high return to player. Both are worth asking about, and the answers live in different places.

Slots. The bulk of every library. RTP is published per title by the software provider; volatility describes how the return is distributed, not how much of it there is. Outcomes come from a random number generator, and no session strategy changes the math.
Progressive jackpots. Headline prizes funded by a slice of every stake. Base-game RTP is usually lower to pay for the pool, and a jackpot win may be paid in installments — check before you assume a lump sum.
Table games. Blackjack, roulette and baccarat generally carry a lower house edge than slots, which is precisely why they're often weighted at a fraction of their stake, or excluded entirely, toward bonus wagering.
Live dealer. Streamed tables with real croupiers. Slower per round, usually higher minimum stakes, and frequently excluded from bonus play.
Mobile. Most of these operators run in a mobile browser; native apps are less common. Ask support whether the app carries the full game catalog before you judge a site on its phone experience.

The other products these operators run

Several of the brands here are not casino-only, and that affects what you're agreeing to. BetUS runs sportsbook and racebook betting alongside its casino, and Bets.FM combines casino play with betting markets — which means bonus terms often distinguish sports wagering from casino wagering, with different rollover rates and different qualifying odds. Card Crush, Zumba Cards and Amazon Jackpots operate on a coins-and-sweeps model rather than a straight cash one, so their "bonuses" are denominated in site currency and their redemption rules are their own thing entirely. Where a single account spans casino, sportsbook and poker, a bonus earned in one vertical rarely clears against play in another. Read which product a promotion belongs to before you use it.

Legal standing, eligibility and where to escalate

You must be 21 or over to gamble online in most US states, and 18 in a small number. Online gambling in the US is regulated state by state, not federally — there is no single national online casino license. A handful of states license and regulate real-money online casinos directly; many more permit only sports betting, lottery or social and sweepstakes-style play; some permit none of it. Federal law governs certain payment and interstate wire activity, but it is your state that decides whether a given site may lawfully offer you real-money casino play.

This matters for one reason in particular: a site accepting registrations from your state is not the same as a site being authorized to serve your state. Before depositing, check the operator's stated licensing and its terms on permitted territories, and check your own state regulator's position. We publish what operators disclose and flag where disclosure is thin; we do not claim licensing status that has not been published.

If you have a dispute an operator won't resolve, the order is: formal written complaint to the casino, keeping copies and reference numbers; escalation to whichever regulator or licensing body the operator names in its terms; and, where an approved alternative dispute resolution service is offered, a referral there. Our editorial background and standards explain what we can and can't verify, and our site terms set out the limits of the information published here. Readers outside the US sometimes reach us about restriction-free options; our guide to casinos outside the GamStop scheme covers that UK-specific territory.

If gambling has stopped being fun

Gambling is entertainment with a cost, never a way to make money or fix a financial problem. Every licensed operator must offer deposit limits, loss limits, time-outs and self-exclusion in the account settings — use them before you need them, not after. Blocking software at the device level and self-exclusion at the state level both go further. In the US, the National Council on Problem Gambling operates the 1-800-GAMBLER helpline, available 24 hours a day. Our responsible gambling resources list the practical tools and where to find them.

Reaching us

Email [email protected] with the page name in the subject line and we'll get to it faster. Corrections with a source attached go to the front of the queue. If you'd rather just tell us a casino paid out slowly, or quickly, that's useful too — reader reports are one of the inputs we use when reviewing whether an operator still belongs on a top list. Information on this page was checked on September 25, 2026; offers and terms change, so treat the operator's own site as the final word.
