Contact Us

You can reach our editorial team by email at [email protected]. That address goes to the people who research and write the reviews on Online Casino Sites, including corrections, questions about bonus terms we've described, and feedback on a casino listed on our pages. We aim to reply within a couple of business days, though complex questions about state availability or payout terms can take longer because we check them before answering.

One thing to know before you write: we are an independent comparison and research publisher, not a casino. We cannot open, close, fund or verify an account for you, we cannot release a withdrawal, and we cannot see your balance or your bonus status. Those requests have to go to the operator's own support desk. Below we've set out what we can help with, what belongs elsewhere, and how to give us information that's actually usable.

What our team can help you with

• Corrections and disputed facts. If a wagering requirement, minimum deposit, withdrawal limit or state restriction on our site no longer matches what the casino publishes, tell us. Include the page and, ideally, a link or screenshot of the operator's current terms.
• Reader experiences. Delays in identity verification, unexpected bonus forfeitures, payout times that didn't match the advertised window — these feed directly into how we describe an operator.
• Questions about terminology. Wagering multiples, maximum bonus bets, bonus expiry dates, cashout caps, RTP, slot volatility, random number generators. We'll explain how a term works generally; we won't advise you on whether to gamble.
• Commercial and licensing enquiries. Partnership, advertising and media requests go to the same inbox and are handled separately from the editorial desk.
• Privacy and data requests. Ask and we'll explain what we hold and how to have it removed.

What you should take to the casino instead

Account-specific matters are between you and the operator, and most have a documented complaints path. Work through it in order:

1. Contact the casino's live chat or support email first and ask for a written ticket reference.
2. If it isn't resolved, escalate to the operator's formal complaints procedure — usually a dedicated address named in its terms and conditions.
3. If the operator holds a state licence, the state regulator that issued it accepts player complaints once the operator's internal process is exhausted. In the US, that is the state gaming authority where the site is authorized, not a federal body.
4. Keep every timestamp, ticket number, screenshot and email. Withdrawal disputes are usually decided on documentation.

If your message to us concerns gambling harm rather than a product, please read our responsible gambling guidance first. It lists deposit and loss limits, self-exclusion routes and blocking software, and points to free, confidential support in the US — including the 1-800-GAMBLER helpline operated by the National Council on Problem Gambling. We can't provide counselling by email.

How we're funded, and why that doesn't change what we tell you

Online Casino Sites earns commission when a reader opens an account with some of the operators we list. Those commercial relationships pay for the research; they don't decide rank order, editorial ratings or whether we publish a criticism. If you believe a listing reads like an advertisement, that's a legitimate complaint to raise with us and we'd rather hear it than not. Our terms and conditions set out the full commercial arrangement, and about our editorial team explains who writes the reviews and how the publisher supplies casino selections.

Questions about a specific operator we list

Most reader mail concerns one of the brands on our top list. Here's the sort of thing we can clarify, and where our knowledge ends, using the three most-asked-about listings as examples.

Raging Bull

Our highest-rated listing at 10.0, and the one that generates the most bonus questions because the advertised offer is large: 410% up to $10,000 plus 50 free spins. A headline percentage that size is almost always attached to conditions that matter more than the number — a qualifying minimum deposit, a wagering multiple applied to bonus funds, a maximum bet allowed while the bonus is live, an expiry date, and frequently a cap on how much of a bonus win can be withdrawn. We can point you to where those clauses sit in the operator's terms and explain what each one does. We cannot tell you whether your particular deposit qualified, and we cannot confirm the offer is available in your state. Limitation to weigh: percentage-led welcome offers of this scale typically carry the heaviest playthrough on the page, which suits high-volume slot players far more than someone planning a few table sessions.

Magician Bet

Rated 9.9 and listed for a different reason — its headline is 101% No Wagering. No-wagering offers are the easiest type to understand, because the value isn't locked behind a playthrough multiple, and readers write to us mainly to confirm that's really what "no wagering" means. Generally it means bonus winnings convert to withdrawable cash without a turnover requirement, but it does not remove every condition: minimum deposit, maximum bet, game weighting and expiry often still apply, and identity verification is still required before any payout. Limitation: a 101% match is modest next to the larger percentages elsewhere on this list, so readers chasing the biggest headline number will find it small.

Slots of Vegas

Also 9.9, with a 375% bonus plus 50 free spins on Cash Chaser. The detail people miss here is that the free spins are tied to a named title, so the spin value, the game's RTP and its volatility are fixed by that choice rather than yours — and winnings from spins commonly carry their own separate wagering and cashout terms, distinct from the deposit match. We can explain how game-specific spins are usually structured. Limitation: a title-locked spins package is worth less to a player who doesn't enjoy that particular slot, and the deposit-match portion still carries standard playthrough.

Other listings you may be writing about

Ratings are our own editorial scores, not customer review averages. Offers are as advertised by the operator and change without notice — always read the current terms on the casino's own site before depositing.

Money questions we're asked most

These come up in almost every inbox, so here is the general shape of the answer. Specific figures belong to the operator, and we'd rather you check them there than trust a number in an email.

• Cost of taking part. Real-money play requires your own deposit. A bonus percentage is applied to money you've committed, so nothing on this page is free. Sweepstakes-style listings that advertise coins or Sweeps Coins work on a different model, where a purchase bundles promotional currency — the redemption rules are what matter there, not the headline.
• Paying in. US casinos commonly support debit cards, credit cards where the issuer permits gambling transactions, ACH bank transfers, wire transfers, prepaid cards and some e-wallets. PayPal availability varies by operator and by state and should never be assumed. Card declines for gambling merchants are common and are a bank decision, not a casino one.
• Getting paid out. Withdrawals typically run back to the method you deposited with where possible. ACH and bank transfer usually take longer to land than e-wallet payouts; check-by-mail is the slowest where offered. Every operator sets its own minimum withdrawal, maximum per transaction or per week, and its own internal review window before funds are released. Advertised payout speeds are marketing claims, not results we've measured.
• Fees. Most deposits are free to the player, but cash-advance charges from a credit card issuer, wire fees and currency conversion can all apply. Ask before you deposit rather than after.
• Verification. Expect KYC: photo ID, proof of address, and proof of the payment instrument. Larger or unusual activity can trigger source-of-funds checks. Uploading documents early is the single most effective way to avoid a first-withdrawal delay.

Game questions: what we can and can't confirm

We're happy to explain how the main categories differ, which is usually what's behind a reader's question. Slots dominate most lobbies and range from low-volatility titles that pay small and often to high-volatility games with long dry spells; progressive jackpots pool contributions across players and pay rarely. Table games — blackjack, roulette, baccarat — have published house edges and usually count less than slots toward bonus wagering, which catches people out. Live dealer rooms stream real tables in real time and often carry lower or zero bonus weighting. Mobile play runs either in-browser or through a dedicated casino app, with lobby size sometimes smaller on mobile.

What we won't do is confirm a catalogue count, a specific game's RTP figure or which software providers supply a given lobby unless the operator publishes it. Those change, and a stale number in an email is worse than no number.

Sports betting and other product lines

Several operators in this market run more than a casino. BetUS, for example, is known to readers as a sportsbook brand alongside its casino product. Where a company runs both, the wallet is often shared but the promotions are not: a casino welcome bonus rarely releases against sports wagers, sportsbook free bets rarely clear casino playthrough, and the two sides can have separate bonus terms, separate maximum stakes and separate withdrawal handling. If you're writing to ask why a bonus didn't apply, that split is usually the reason. We cover the casino side; questions about odds, parlays or settlement rules need the operator's sportsbook support.

Legal standing and who may contact us

This site is for adults aged 21 and over in the United States. Online casino gambling in the US is regulated state by state: a handful of states license and regulate real-money online casino play, several more permit only online sports betting, and in many states real-money online casino gambling is not authorized at all. There is no single federal licence that permits an operator to serve players nationwide, and an operator accepting sign-ups from your state is not the same thing as being authorized to serve it. Sweepstakes and social-casino models operate under different rules again, and their availability also varies by state.

Before you deposit anywhere, confirm the operator's licensing position and check what it says about your state. If you're outside the US, note that our guide to casinos not on GamStop covers the UK market and different rules apply there. Nothing on Online Casino Sites is legal advice, and nothing here should be treated as a way to make money — gambling costs more than it returns over time, and any funds you commit should be money you can afford to lose.

How to write a message we can act on

1. Name the casino and the page on investmentcontrarians.com you're referring to.
2. Say what you saw versus what we published, with dates.
3. Attach evidence — the operator's terms page, a screenshot, a support ticket reference.
4. Redact your account number, full card details and any ID document. We never need them and don't want them.
5. Tell us if you'd like your experience quoted anonymously, or kept entirely private.
