Contact Us
This page is for getting in touch with the editorial team behind Online Casinos. Use it if you have spotted an error in a review, want a newer casino brand assessed, need pointing toward the right regulator for a complaint, or have a question about how our rankings work. Send your message through the contact form or email address published on themillennialmarketers.com, and include enough detail that we can act on it without a second round of questions.
One thing to be clear about first: we are a research and comparison publisher, not a casino operator. We do not hold player accounts, process deposits, pay out winnings, issue bonuses or verify identity documents. If your issue is with money sitting in an account somewhere, the operator's support desk is the only place that can move it. We can tell you what to ask them and where to escalate.
What to include so we can actually help
- The casino brand name, exactly as it appears on the site you used.
- Your state of residence — legal availability, licensing and player protections differ from one state to the next, and the answer often turns on this.
- The date of the event, in US format (for example 09/12/2026).
- What you were told, by whom, and through which channel — live chat transcript, email, in-account message.
- Screenshots of the relevant bonus terms, cashier screen or support reply, if you have them.
Leave out full card numbers, bank account details, Social Security numbers and copies of ID. We never need them, and we will not ask for them. Anyone claiming to be from Online Casinos who does ask is not from Online Casinos.

How we make money, stated plainly
Some links on this site are commercial. If you follow one, open an account and deposit, we may be paid a commission by the operator. That funding pays for the research. It does not buy a position, a rating or a kinder write-up, and we will not remove a documented drawback because a partner asks. If you ever think a page reads like an advert rather than an assessment, say so in your message and quote the line — those emails get read carefully.
The casinos readers ask about most
These three come up more than any others in our inbox, usually because the headline numbers are large. Here is the shape of each, including the parts that generate the complaints.
Raging Bull — the biggest advertised match, and the most questions
Raging Bull sits at the top of our list with an editorial rating of 10.0 and an advertised 410% up to $10,000 plus 50 free spins. It is on this page because more readers write to us about it than any other brand, and most of those messages are about the bonus rather than the games. A percentage that size is a play-through commitment, not a cash gift: the match funds arrive locked, and wagering requirements, maximum bet caps while a bonus is active, expiry dates and cashout limits all apply. Read the promotion terms before you deposit — the $10,000 figure assumes a deposit most players will never make. Limitation: the headline is the least useful number on the page, and the practical value depends entirely on terms that can change without notice.
Magician Bet — no-wagering terms, smaller ceiling
Rated 9.8, with a 101% no wagering offer. We include it because it answers the single most common complaint we receive, which is bonus money that cannot be withdrawn. A no-wagering structure means the bonus is not chained to a play-through multiple, so what you win is ordinarily yours to withdraw subject to normal account checks. That is a genuinely different proposition from a 400% match. Limitation: no-wagering offers are almost always smaller and often carry their own caps — maximum bonus amount, minimum deposit, eligible games, a short claim window. Check whether the term applies to the deposit match, the spins, or both.
Slots of Vegas — a game-specific spins offer
Rated 9.6, advertising a 375% bonus plus 50 free spins on Cash Chaser. Worth knowing about because the spins are tied to one named title, which is common and frequently misread. Spins locked to a specific game mean the return to player and volatility of that game decide what the offer is worth to you, and winnings from spins usually carry their own wagering and a cap on what can be converted to cash. Limitation: a game-restricted promotion suits players happy to play that game and nobody else, and the 375% match carries the same play-through considerations as any large percentage offer.
Others on the list
Uptown Aces (9.4) advertises 600% for new players; Card Crush (9.4) an instant welcome reward of 2 mystery coins and 5 cards; Zumba Cards (9.3) a 250% deposit bonus up to 250 SC; BetUS (9.1) 200% up to $4,000; Amazon Jackpots (8.8) 4 posters plus 40 free SC and a bonus wheel for $20; Slots and Casino (8.7) 500% up to $2,500 across three deposits; and Bets.FM (8.5) a 225% deposit bonus up to 1 BTC with 225 free spins. Note the different currencies in play — dollars, sweeps coins and bitcoin are not interchangeable, and the rules governing each differ. Ask us about any of them and we will tell you what we have verified and what we have not.
Money questions we get asked constantly
Deposits and withdrawals produce more mail than games do, so here is the general picture. Minimum deposits at US-facing casinos commonly start in the $10 to $25 range, and a bonus usually has its own qualifying minimum that can be higher than the cashier's. Minimum withdrawals are often set higher than minimum deposits, which catches people out.
- Debit cards — the most widely accepted deposit route. Payouts back to a debit card are not always offered.
- Credit cards — may be accepted for deposits, but your card issuer can decline or treat the transaction as a cash advance with its own fee and interest. Never a withdrawal method.
- ACH and bank transfer — typical for larger withdrawals; slower to land, often the cheapest.
- E-wallets — usually the quickest payout option where offered. PayPal availability at US casinos is patchy and depends on the operator and your state, so verify it in the cashier rather than assuming.
- Crypto — used by some operators, including for the bitcoin-denominated offer above. Value moves between deposit and withdrawal, and that movement is yours to absorb.
On timing: an advertised withdrawal speed starts when the payment leaves the operator, not when you click the button. Before that comes a pending or reversal window, then KYC identity verification, and sometimes source-of-funds checks on larger sums. Weekly and monthly withdrawal limits apply at many sites, and a large win can be paid in installments as a result. Fees vary by method and by amount, so check the cashier page rather than the marketing page. We publish no guarantees about payout speed at any casino, and neither should anyone else.
Game questions we can answer
If your message is about what is actually available to play, we cover these categories:
- Slots — including RTP figures, volatility and how progressive jackpots pool across a network.
- Table games — blackjack, roulette and baccarat, where rule variants change the house edge more than most players expect.
- Live dealer rooms — real tables streamed with human croupiers, higher minimum stakes, and frequently excluded from bonus wagering.
- Mobile play — browser versus a dedicated casino app, and what each does to game selection.
Outcomes in digital games come from random number generators, which independent testing houses certify at licensed operators. We can tell you what a published RTP means over the long run. We cannot tell you what will happen on your next session, and we will not pretend otherwise.
Sportsbooks, poker and the rest
Several brands on this list run more than a casino. BetUS, for one, is known primarily for sports betting alongside its casino floor, and other operators here attach poker rooms, bingo or sweepstakes-style card play. Those product lines have separate promotions, separate wagering rules and sometimes a separate wallet. A casino welcome offer generally does not fund sports wagers, and sportsbook rollover is calculated differently. If you are contacting us about a bonus, tell us which product it was attached to — it changes the answer.
Legal standing, eligibility and where complaints go
You must be at least 21 to gamble online in most US states that license it, and 18 in a small number of jurisdictions and for some sweepstakes products. Online casino gambling is regulated state by state. There is no federal license for online casinos; individual state gaming authorities issue them, and a site legal in one state may be unavailable in the next. An operator accepting deposits from your state is not the same as being authorized to serve it — those are separate facts and we treat them separately.
Where a casino is state-licensed, you have a defined complaints path: the operator's internal procedure first, in writing, then escalation to the state regulator if you are not satisfied. Offshore and sweepstakes operators sit outside that framework, and your practical recourse is narrower. Check what applies before you deposit, not after a dispute starts. Our site terms set out the limits of what we publish, and readers comparing offshore options can see how a different regulatory regime works on our page covering casinos outside the UK self-exclusion scheme.
If gambling is causing harm, contact the National Council on Problem Gambling helpline at 1-800-GAMBLER, use the operator's self-exclusion and deposit or loss limit tools, or install blocking software on your devices. You do not need to write to us first.
Response times and corrections
Messages are read by the editorial team, with fact-check queries handled by Madison Hayes. We do not publish a guaranteed reply window, because the honest answer is that it depends on volume and on how much verification a claim needs. Corrections are prioritized over everything else: if you can show that something we published is wrong, we will check the source and amend the page, and the update date at the top of it will change.
Not sure whether your question is one for us? Send it anyway and we will either answer it or tell you who can. If you would rather read about our methods before writing, how we research and rate casinos explains what goes into a rating and what does not.
