You have reached the contact page for Top Online Casinos, an independent research and comparison site covering US online casinos. Use this page to reach our editorial team with corrections, questions about bonus terms, or feedback on anything we have published at cliffslater.com. It also explains what we cannot do — we are not a casino, we hold no player accounts, and we cannot release a withdrawal, verify your ID or settle a dispute on your behalf.

How to Reach the Editorial Team

Every message goes to the same editorial inbox, reachable through the contact form on this page. There is no phone line and no live chat — we are a small publishing team, not a support desk, and written messages let us check facts before replying. To get a useful answer first time, include:

  • The page on cliffslater.com you are writing about, and the section or table if you can name it
  • The casino brand involved, if your question is about a specific offer
  • The state you are playing from, since availability and terms vary state by state
  • What you expected versus what you found — for corrections, a link or screenshot of the operator's own terms helps most

Never send us passwords, full card numbers, Social Security numbers or copies of ID documents. We have no use for them and no reason to hold them. If a message arrives containing that material, we delete it.

What we can help with

  • Factual corrections to bonus percentages, caps, wagering multiples, expiry windows or state availability we have published
  • Explaining how a term in one of our guides works — for example what a maximum bonus bet or a cashout cap means in practice
  • Pointing you to the right regulator, ombudsman or support organization for a complaint
  • Press, partnership and advertising inquiries

What we cannot help with

  • Account access, password resets or closed accounts at any casino
  • Releasing a pending withdrawal, reversing a confiscated bonus or overturning a KYC decision
  • Issuing bonus codes, free spins or sweeps coins — only the operator can do that
  • Legal advice on whether a particular site may lawfully serve you in your state

Where to Take a Casino Complaint First

Contacting us does not start a complaint. It has to go to the operator, then to a regulator or dispute service. The order matters, because regulators generally expect the operator to have had a chance to respond.

  1. Open a ticket with the casino. Use in-account support so there is a written trail. State the date, amount, payment method and the term you believe was misapplied.
  2. Ask for a final response. Most complaint procedures escalate to a manager or a formal complaints handler. Request that decision in writing.
  3. Escalate to the regulator. If the site is licensed by a US state gaming authority — for example a state gaming commission or division of gaming enforcement in a state that has legalized online casino play — that regulator handles player disputes for sites it licenses. Offshore-licensed sites have no US regulator to escalate to, which is a material difference before you deposit.
  4. Keep your own records. Transaction history, bonus terms as they appeared on the day, and support transcripts. Operators can and do change promotional terms.

If gambling itself is the problem rather than one transaction, the 1-800-GAMBLER helpline operates nationally and most state programs run their own self-exclusion registers. Our responsible gambling guide covers deposit limits, loss limits, cooling-off periods and blocking software in more detail.

Our Commercial Relationships, Stated Plainly

Top Online Casinos earns money through affiliate links. If you follow a link to a casino and open an account, we may be paid a commission. That revenue funds the research; it does not buy a position, a rating or a kind word. We publish limitations on every brand we rank, including the top one, and we decline to rank sites we cannot verify. If you believe commercial interest has crept into something we published, say so through this page — that is exactly the message we want.

Questions We Get About the Brands We Rank

Most contact messages are about the headline offers on our lists. The three below account for the bulk of them, so here is what we would say in reply. Every figure is the operator's own advertised term as recorded on Sep 25, 2026; check the promotion page before you deposit, because these change without notice.

Raging Bull — 410% up to $10,000 + 50 free spins

It sits at the top of our list on editorial rating (10.0) because the advertised match rate and ceiling are the largest on the page by a wide margin, which is what readers searching for the biggest bonus are looking for. That size is also the reason people write to us about it. A headline like 410% up to $10,000 requires a deposit large enough to reach the cap, and the percentage applies to your deposit, not to a fixed award. Before claiming, read the wagering multiple, the maximum bet allowed while a bonus is active, the expiry window and any cap on what you may cash out from bonus play — a capped cashout can make a very large nominal bonus worth far less than it reads. The 50 free spins are usually tied to named games and carry their own playthrough. Limitation: the more aggressive the match, the more restrictive the attached terms tend to be, and this is a bonus that rewards careful reading rather than a quick claim.

Magician Bet — 101% no wagering

This is the counterweight on our list, rated 9.9, and it is the one we point readers to when they tell us wagering requirements are the part they find unworkable. A no-wagering offer means the credited amount is not locked behind a playthrough multiple, so what you win is not trapped behind a rollover calculation. The trade-off is scale: 101% is modest next to a 400% or 600% match. Limitation: "no wagering" rarely means "no conditions" — expect minimum deposit thresholds, maximum bet rules while the offer is live, game weighting and a time limit, and confirm the cap on the matched amount before you assume it applies to a large deposit.

Uptown Aces — 600% for new players

The largest advertised match percentage on our list, rated 9.7. It earns its place for readers whose deposits are small, since a high multiplier on a modest deposit is where a percentage-led offer does the most work. Limitation: the advertised figure comes without a stated ceiling in the material we hold, and an unstated cap is the single most common reason a bonus pays out less than a reader expected. Treat the maximum bonus amount, the playthrough multiple and any cashout limit as the three numbers to confirm on the operator's terms page before depositing.

Comparing the Headline Offers Before You Write to Us

Often the answer to an incoming question is visible in a side-by-side view. These are the advertised offers and our editorial ratings — our own assessment, not customer review scores — for the brands currently on our list.

Slots and Casino500% up to $2,500 x39.2Multi-deposit match
Bets.FM225% up to 1 BTC + 225 free spins9.2Crypto match + spins

All offers are for new players, subject to the operator's terms, minimum deposits and time limits. Sweeps coin packages such as those from Zumba Cards and Amazon Jackpots work on a different model from cash-deposit casinos, and Bets.FM quotes its ceiling in bitcoin, so the dollar value moves with the exchange rate.

Money Questions: Deposits, Payouts and Fees

We cannot process a payment or chase one, but we can tell you what to check. Costs of taking part fall into three buckets: the minimum deposit needed to qualify for an offer, any fee the payment method itself charges, and the conditions that decide whether a balance can leave the account.

  • Deposits. Debit cards are the most widely accepted method at US-facing casinos. Credit card deposits are accepted by some operators and declined by some issuers, who may also treat the transaction as a cash advance with its own fee and interest. ACH bank transfer, online banking and prepaid options appear at many sites; e-wallet and PayPal availability varies by operator and by state, so verify it in the cashier rather than assuming.
  • Withdrawals. Expect a stated minimum withdrawal, a per-day, per-week or per-month limit, and a processing window that runs separately from the banking time. Advertised timeframes are the operator's own claims, not results we have measured.
  • Fees. Some casinos absorb them, some pass them on, and some charge for a second withdrawal in the same period. Crypto payouts carry network fees that the casino does not set.
  • Verification. KYC identity checks are routine and are usually where a first withdrawal slows down. Larger or unusual amounts can trigger source-of-funds checks. Completing verification before you request a payout is the single most effective thing you can do to avoid a delay.

If a payout stalls beyond the operator's own stated window and support gives no reason, that is the point to ask for a final response in writing and escalate.

What These Sites Actually Offer

The brands on our list are casino-led, and their libraries generally break into the same categories. Slots make up the bulk — low-volatility games that pay small and often, high-volatility games that pay rarely and larger, and progressive jackpots that pool a slice of every stake into one prize. Return to player, or RTP, is the long-run theoretical payback percentage published for each game, and volatility describes how bumpy the ride to that average is; both are worth checking in the game info panel. Table games cover blackjack, roulette and baccarat in software form, with outcomes set by a random number generator. Live dealer rooms stream a real table with a real dealer and usually carry higher minimum stakes and fixed opening hours. Mobile play is generally browser-based, with dedicated apps at some operators but not all.

The products these operators run alongside the casino

Several brands here are not casino-only. BetUS, for instance, is known for sportsbook markets running beside its casino, and mixed operators commonly add poker rooms, racebooks or virtual sports. The distinction matters for bonuses: a sportsbook welcome offer and a casino welcome offer are usually separate promotions with separate playthrough rules, and casino bonus funds typically cannot be wagered on sports. Sweeps-style sites such as Card Crush, Zumba Cards and Amazon Jackpots run on coin packages and prize redemptions rather than straight cash wagering, which changes both the bonus math and the redemption process. Ask us about the difference if a promotion page is unclear — that is a fair question for this inbox.

Who Can Use These Sites, and Under What Rules

US online gambling is regulated at state level, not federally. Federal statutes shape payment processing and interstate activity; whether you may legally play online casino games, and which operators are authorized to offer them, is decided by your state. A handful of states license real-money online casino play and run their own regulators, complaint routes and self-exclusion registers. Many do not. Sweepstakes and social casino models operate under a different legal theory again and are unavailable in some states regardless.

Two practical points we repeat often, because they are the ones readers get wrong:

  • A site accepting deposits from your state is not the same as a site being authorized to serve your state. Accepting customers and holding a licence for them are separate things.
  • If a site is not licensed by a US state regulator, no US regulator adjudicates your dispute. Whatever protections exist come from the operator's own licensing jurisdiction, which may be offshore.

Everyone must be at least 21 at the operators on this page, and age minimums, identity verification and geolocation checks are standard. We do not advise on the legality of any specific site in any specific state — that is a question for a qualified attorney or your state regulator. Our terms and conditions set out the limits of what we publish, and our editorial approach explains who we are and how we research.

How We Handle Your Message

  • Corrections are checked against the operator's published terms and, where confirmed, updated with the date of the change noted.
  • Questions about terms get a plain-language answer and a pointer to the guide that covers it in full.
  • Complaints about an operator get the escalation route above. We log them, and a pattern of similar reports about one brand feeds into our review of it.
  • Commercial inquiries are handled separately from editorial and never influence a ranking.

We aim to reply to every genuine message, though volume varies and we do not guarantee a response time. Anything we cannot verify, we will tell you we cannot verify rather than guess.


If your question is really about which offer suits you, the short version: the biggest headline percentage is not automatically the best value, because wagering multiples, maximum bets and cashout caps decide what a bonus is actually worth. Read the terms beside the number, start with an amount you are comfortable losing, and set deposit limits before you play rather than after. Then write to us if something still does not add up — we would rather answer the question than have you find out the hard way. If gambling has stopped being entertainment, call 1-800-GAMBLER.
