Contact Us
You can reach the Online Casino Sites editorial team by email at [email protected]. We read everything that arrives, and we aim to reply to genuine reader questions within a couple of working days. This page explains what we can help with, what we can't, and where to take the issues that need an operator, a regulator or a support organization rather than a review site.
What to include so we can actually help
Most emails we can't answer are missing context. A message that says "the bonus didn't work" gives us nothing to check. A message that names the casino, the date and the exact wording of the term gives us something to verify against the operator's published rules.
- The casino name as it appears on our page — for example Raging Bull or Slots of Vegas, not an affiliate redirect or a lookalike domain.
- The date the issue happened, in US format, and the state you were playing from.
- What you were told, and by whom — live chat transcript, email, or the section of the terms you're reading.
- What you expected instead, and what you've already tried.
- Screenshots where they help. Never send us passwords, full card numbers, Social Security numbers or copies of your ID.
We do not hold accounts with the operators listed here, we cannot see your balance, and we cannot release a withdrawal, reverse a wagering requirement or reopen a closed account. Anyone who tells you otherwise is not us.
Reporting an error in a review or a changed offer
Casino terms move fast. Bonus percentages get cut, free spin counts change, payment methods drop out in particular states, and withdrawal limits get rewritten without notice. If you find something on this site that no longer matches what the operator publishes, tell us and we will check it against the casino's own terms page.
Corrections we act on quickest are the ones with a source: a link to the operator's terms, a dated screenshot of the promotion page, or a copy of an email from their support team. Our pages carry a fact-check date — the current one is Sep 25, 2026 — and a correction resets it. Where a claim is contested and we can't verify it either way, we say so on the page rather than picking a side.
How our commercial relationships work
Some links on this site are commercial. If you open an account through one, we may earn a commission from the operator. That is how the research gets paid for. It does not buy a position in our rankings, it does not soften a review, and it does not stop us publishing a limitation. Our editorial ratings are our own assessment, not customer review scores, and no operator sees a review before it goes live.
The operators readers contact us about most
Three names generate more mail than the rest, usually because their headline offers are the largest and the conditions attached are the ones people want explained. Here is the short version of what we tell them. The offers below are as advertised by the operator; always read the current terms on the casino's own site before depositing, since they can change after our last check.
Raging Bull — 410% up to $10,000 + 50 Free Spins
It sits at the top of our list and carries our highest editorial rating, 10.0, largely because the headline deposit bonus is unusually deep and the free spins come attached to it rather than being sold as a separate no-deposit hook. Readers mostly write in about the ceiling: a 410% match "up to $10,000" is a maximum, not a typical outcome, and you would need to deposit near the cap to see anything close to it.
The limitation worth knowing before you email us about a stalled cashout: large percentage matches almost always come with playthrough on the bonus and often on the deposit too, plus maximum bet caps while a bonus is live and a cap on how much of a free-spin win can be withdrawn. Breaking a max-bet rule by a dollar can void a balance. Check the wagering multiplier, the expiry window and the cashout cap in the operator's terms before you claim.
Magician Bet — 101% No Wagering
Rated 9.9, and it appears here for one reason: a no-wagering offer is a genuinely different product from a percentage match. If there is no playthrough, what you win is withdrawable subject to the normal account rules, which removes the single biggest source of reader complaints we see.
The trade-off is size. A 101% match is modest next to a 410% or 600% headline, and no-wagering promotions typically carry tighter maximum deposit amounts, shorter validity and sometimes a cap on winnings from bonus funds. "No wagering" also does not mean "no verification" — identity checks still apply before a first withdrawal.
Slots of Vegas — 375% Bonus + 50 Free Spins on Cash Chaser
Rated 9.8. The distinguishing feature is that the free spins are tied to a named title, Cash Chaser, rather than being usable anywhere. That matters more than it sounds: a game-locked spin package means the RTP and volatility of that one slot decide what the spins are worth to you, and you can't move them to a game you prefer.
The limitation is the same game restriction seen from the other side, plus the usual structure of a high-percentage match — expect playthrough, a maximum bet while the bonus is active, and an expiry date on both the bonus and the spins. If slots aren't your game, a spins-heavy offer is worth less to you than the headline number suggests.

Ratings are our editorial assessment based on published terms, transparency and the practical value of the offer. They are not user review scores, and none of them is a prediction of what you will win.
Money questions we get asked before anything else
Cost of entry is the first thing readers ask about, and it is rarely just the deposit. A 500% match on a $25 deposit is not the same product as the same match on $500, and a bundle priced at a fixed $20, as Amazon Jackpots advertises, is a purchase rather than a bonus on money you were depositing anyway.
- Minimum deposits. Each operator sets its own floor, and a bonus often has a higher minimum than the account does. Depositing below the bonus threshold usually means no bonus and no way to claim it retroactively.
- Paying in. Availability for US players varies by operator and by state. Debit cards are the most widely accepted; credit card deposits are frequently declined by US issuers as gambling transactions; ACH bank transfers and wire transfers are common for larger amounts; e-wallets and PayPal appear at some operators but not all, and PayPal in particular is generally limited to state-regulated sites. Bets.FM prices its welcome offer in Bitcoin, which tells you crypto is central there — and that the dollar value of a 1 BTC cap moves with the market.
- Getting paid out. Withdrawals usually return by the method you deposited with where possible. Expect a minimum withdrawal amount, a per-day or per-week limit, and a review period before funds are released. Crypto cashouts tend to clear faster than checks by courier, which are the slowest option still in wide use.
- Fees. Deposits are commonly free; withdrawals may carry a processing fee, a fee for more than one cashout per period, or a network fee on crypto. Check the cashier page, not the promotion page.
- Verification. Before a first withdrawal you will be asked for KYC documents — photo ID, proof of address, and proof of the payment method. Larger or unusual amounts can trigger source-of-funds checks. Submitting documents early is the single most effective way to avoid a delayed payout.
If a withdrawal stalls, start with the operator's own complaints procedure and keep everything in writing. If they don't resolve it, escalate to the licensing body named in their terms. We can't arbitrate a dispute, but we do log patterns, and repeated credible reports about the same operator affect how we write about it.
What these sites actually offer to play
Readers sometimes contact us assuming every casino here carries the same catalog. They don't, and the differences decide which welcome offer is worth claiming.
- Slots. The core of most of these sites, and where nearly all free spins must be used. Return to player and volatility are the two numbers that matter: RTP is the long-run theoretical return, volatility describes how bumpy the ride is. A game-locked package like the Cash Chaser spins at Slots of Vegas is only as good as that title.
- Progressive jackpots. Pooled prizes that grow until someone wins. Often excluded from bonus play or capped for bonus cashout — check before you assume a jackpot win on bonus funds is fully withdrawable.
- Table games. Blackjack, roulette and baccarat. These usually contribute far less toward wagering requirements than slots, sometimes nothing at all, which is why a table-game player gets less out of a big percentage match than the headline implies.
- Live dealer. Real tables streamed in real time. Contribution toward playthrough is typically low or zero, and some bonuses exclude live rooms entirely.
- Sweepstakes and card formats. Card Crush and Zumba Cards run on a different model, with sweeps coins and card-based rewards rather than a straight dollar match. The currency in an offer like "250 SC" is not dollars, and redemption rules differ from a cash casino withdrawal.
Game fairness on regulated sites rests on random number generators tested by independent labs, and on software providers publishing RTP figures. Where an operator doesn't publish either, that's worth noting before you deposit.
The other products these brands run
Several operators on this list are not casino-only, and readers contact us confused about which set of terms applies. BetUS, for instance, is best known in the US for sports betting alongside its casino, and its 200% up to $4,000 welcome offer for new players sits next to separate sportsbook promotions with different playthrough rules. Mixing the two — claiming a casino bonus and then betting sports with it — is a common way to void a balance.
Other adjacent lines you'll see across these brands include poker rooms, racebooks, bingo, virtual sports and loyalty or VIP programs that pay cashback on losses rather than a bonus on deposits. Cashback and loyalty rewards are often the better long-run value for a regular player, because they usually carry lighter wagering than a welcome match. Each product line has its own terms, its own contribution rates and sometimes its own wallet.
Who can use these sites, and under what rules
You must be at least 21 to gamble online at most US operators, and 18 or 21 depending on the state and the product. Online casino gambling in the United States is regulated state by state, not federally. A handful of states license and regulate real-money online casinos directly; many more permit online sports betting only; others permit neither. Federal law sets boundaries around interstate wire transmission and payment processing, but it is state law that decides whether a licensed online casino can serve you where you live.
Two things readers regularly conflate, and we want to be exact about the difference: an operator accepting deposits from US customers is not the same as that operator being authorized to serve them. Some sites listed here are offshore and licensed elsewhere; some run on a sweepstakes model that operates outside conventional gambling licensing; some are state-licensed. The consumer protections you get — complaints escalation, dispute resolution, segregated funds, mandated responsible gambling tools — depend entirely on which of those applies. Before you deposit, find the licensing statement in the site footer, check which authority issued it, and check whether your state is on their restricted list.
Obligations follow you too: gambling winnings are taxable income in the US, accounts must be in your own name, and using a VPN to disguise your location breaches almost every operator's terms and is a standard reason for confiscated balances. We can't give legal or tax advice on any of this, and a message asking whether a specific site is legal in your specific state is one we'll answer with "check your state regulator," because that is the only accurate answer.
If gambling has stopped being entertainment
We're a research site, not a support service, and we can't provide counseling. If you need help now, the National Problem Gambling Helpline is available 24/7 at 1-800-522-4700, by call or text, and offers chat support. Many states run their own helplines and voluntary self-exclusion registers.
Practical tools worth using before things get difficult: deposit and loss limits set inside your account, session time reminders, cooling-off periods, self-exclusion from an individual operator or a state-wide scheme, and device-level blocking software that prevents access to gambling sites entirely. Our responsible gambling guidance goes through each of these and how to set them up. Gambling is entertainment with a cost attached; it is not a way to make money or fix a financial problem.
Other ways to get what you came for
Some questions are answered faster on the site than by email.
- Who writes here, how we research and how we're funded: about the editorial team.
- Rules covering use of this site and our links: terms and conditions.
- Our coverage of casinos operating outside GamStop, which applies to UK self-exclusion rather than US state schemes — worth knowing if you landed there by mistake.
For anything else — a correction, a question about a bonus term you can't parse, a tip about an operator behaving badly, or a note that something on this page is out of date — write to [email protected] and include the detail listed at the top. Nathan Barrett and the Online Casino Sites team review reader mail as part of each update cycle, and reader reports are one of the main reasons pages get rechecked ahead of schedule.
