About Us

Online Casino Sites is an independent research and comparison publisher covering US online casinos, with a particular focus on free spins and the bonus terms attached to them. This page explains who writes the site, how the rankings on thehappytudor.com are put together, how we earn money, and — just as importantly — what our ratings cannot tell you.

We are not a casino, a sportsbook or a payment provider. We do not accept deposits, hold player funds or take bets. Everything here is editorial: research into operator terms and conditions, bonus mechanics, payment options, licensing claims and player-protection tools, written for adults aged 21 and over in the United States.

Why this site leads with free spins

Free spins are the most advertised and least understood part of a US online casino welcome offer. A headline like "50 Free Spins" tells you almost nothing on its own. What decides whether the spins are worth anything are the details underneath: the per-spin value, the single game or small group of games they apply to, the wagering multiplier applied to winnings, the cap on how much you can ultimately cash out, and how many days you have before the spins expire.

So that is where our attention goes. When we look at an offer such as Raging Bull's 410% up to $10,000 + 50 Free Spins, the percentage is not the interesting part — the conditions on those 50 spins usually are. We read the terms as published by the operator and describe what we find, flagging anything we could not verify rather than filling the gap with a guess.

How we make money, stated plainly

Online Casino Sites is free to read because it carries commercial links. If you follow a link from one of our pages to an operator and open an account, we may be paid a commission. That is the whole business model, and it is disclosed before any ranked list rather than buried at the foot of the page.

Two things follow from that, and we hold to both:

• Commission does not buy position. Operators cannot purchase a higher rank, a better editorial rating or the removal of a criticism. Where a site has a weakness we consider material, it appears in the write-up regardless of the commercial relationship.
• Not everything we cover pays us. Some operators we write about have no commercial arrangement with us at all, and some offers we describe are ones we would not personally take.

Our editorial ratings — the scores from 10.0 downwards shown on our comparison cards — are our own assessment. They are not customer satisfaction scores, not survey results, and not an audit. They are one publisher's opinion, formed from documented research.

What our research actually involves

We want to be exact about this, because the phrase "we tested it" gets used far too loosely in this industry. We do not claim to have deposited money, played through bonuses or made withdrawals at the casinos we cover. What we do is research and verification:

1. Read the full terms. Welcome bonus rules, free spins conditions, wagering requirements, maximum bonus bet limits, expiry dates and bonus cashout limits — the whole document, not the promotional banner.
2. Check licensing and jurisdiction claims. We look at what an operator states about its regulation and ownership, and we distinguish between a site accepting US customers and a site being licensed by a US state regulator to serve them. Those are not the same thing.
3. Record payment and withdrawal terms as published. Minimum deposits, minimum withdrawal amounts, withdrawal limits, stated processing times and any fees.
4. Look at the games and the software behind them. Slot ranges, progressive jackpots, live dealer tables, blackjack, roulette and baccarat variants, plus the providers supplying them and any published RTP information.
5. Check the player-protection tools. Deposit and loss limits, session reminders, self-exclusion, and how the complaints procedure is described.
6. Date what we find. Terms change without notice. Our findings carry a fact-check date — currently Sep 25, 2026 — and we re-check pages as offers move.

Where a detail is not published or we cannot confirm it, we say so rather than inventing a number. Advertised withdrawal speeds are reported as advertised, never as measured.

How the ranked list is built

Our order reflects the weight we give free spins and bonus quality, not the size of the headline number. Two offers illustrate the difference:

Operator	Headline offer	Editorial rating	What our research focuses on
Raging Bull	410% up to $10,000 + 50 Free Spins	10.0	Spin eligibility, wagering on spin winnings, cashout cap
Magician Bet	101% No Wagering	9.9	What "no wagering" excludes, and any withdrawal minimums
Slots of Vegas	375% Bonus + 50 Free Spins on Cash Chaser	9.6	Single-game restriction on the spins, expiry window
Uptown Aces	600% For New Players	9.6	Whether the percentage is split across deposits
Bets.FM	225% deposit bonus up to 1 BTC + 225 Free Spins	9.1	Crypto-denominated terms and spin release schedule

Three examples of how we write about an operator

Raging Bull — the largest free spins package on our list

Raging Bull sits at the top because its offer combines a very large match percentage with a named free spins allocation, which is the exact shape of offer this site exists to unpick. The 410% up to $10,000 plus 50 free spins is available to new players only, and — like every deposit-match promotion — requires you to fund the account with your own money first. The percentage is the advertised maximum, and playthrough must be completed on winnings before a withdrawal is possible. Limitation: very high match percentages generally travel with correspondingly high wagering requirements and low maximum bet caps while a bonus is active, and free spins on this kind of package are typically tied to specific slots. Read the promotion page in full before depositing; the headline figure is the least binding part of it.

Magician Bet — the offer that changes the maths

Magician Bet earns second place for a structural reason rather than a generous one. A 101% No Wagering bonus is smaller than almost everything else here, but if winnings genuinely carry no playthrough, the money behaves differently from a 400% bonus locked behind a multiplier. That trade — less headline value, fewer strings — is worth understanding before you compare percentages across sites. Limitation: "no wagering" rarely means no conditions at all. Minimum deposits, game restrictions, maximum win caps and withdrawal minimums can still apply, and we have not independently confirmed how each of those is applied in practice.

Slots of Vegas — free spins pinned to one game

Slots of Vegas makes the list because its 375% bonus plus 50 free spins on Cash Chaser is an unusually clear example of a game-specific spin offer. That clarity is useful: you know exactly which title the spins run on before you opt in. Limitation: a single-game restriction is also the constraint. If that slot's volatility or theme does not suit you, the spins have little practical value to you, and any winnings will still be subject to the promotion's wagering and cashout terms. The deposit match, again, requires your own funds to activate.

Money, deposits and getting paid — what we check

Taking part in any of these offers costs money. Apart from genuine no-deposit promotions, a bonus requires a qualifying deposit of your own, and that deposit is at risk in play. We never describe a deposit-match offer as free.

On each casino page we record, where the operator publishes it:

• Minimum deposit to open an account and to qualify for the promotion — these are often different figures.
• Payment methods available to US customers — commonly debit cards, credit cards (which some card issuers decline for gambling), ACH bank transfer, wire transfer, e-wallets and, at some sites, cryptocurrency. PayPal availability varies by operator and by state, so we verify it rather than assuming it.
• Minimum withdrawal amount and withdrawal limits, daily, weekly or monthly.
• Advertised processing times, separating the operator's internal approval window from the time your bank or wallet takes afterwards.
• Fees, including any charged on a second withdrawal in a period or on specific methods.

One point we repeat across the site because it causes the most disputes: identity verification. Expect KYC checks — photo ID, proof of address, sometimes proof that the payment card belongs to you — and at higher amounts, source-of-funds questions. Completing verification early, before your first withdrawal request, is the single most effective way to avoid a delay. If a withdrawal is refused and you believe it is wrong, use the operator's published complaints procedure first, then the relevant regulator or dispute service.

What these sites offer beyond free spins

The casinos we compare are not single-product businesses, and the coverage on thehappytudor.com reflects that:

• Slots — the core of most US casino lobbies, including progressive jackpot titles. We look at published RTP figures and volatility where providers disclose them.
• Table games — blackjack, roulette and baccarat, in RNG form with varying rule sets and house edges.
• Live dealer rooms — streamed tables with real dealers, usually with higher minimum stakes and different bonus contribution rates.
• Sweepstakes and coin-based play — several operators, including Card Crush, Zumba Cards and Amazon Jackpots, use coin or sweepstakes-style models rather than conventional cash deposits. The rules for redeeming winnings differ substantially from a real-money casino, and we treat them as a separate category rather than lumping the two together.
• Sports betting — BetUS, for example, runs a sportsbook alongside its casino. Sportsbook promotions carry their own rollover terms, and casino bonus funds usually cannot be used on sports markets. Where an operator runs both, we say which product a promotion applies to.
• Mobile play — browser-based lobbies and native apps, and whether game availability differs between them.

Who can legally play, and what that means for you

US online casino regulation is set at state level, not federally. A handful of states license and regulate online casino gaming directly; many do not. Federal law governs certain adjacent matters, but there is no single national online casino licence. The practical consequences for a reader:

• You must be at least 21 in most regulated states, and physically located in a state where the operator is permitted to offer play.
• State-licensed operators use geolocation checks. If a site does not check your location, that tells you something about its licensing.
• An operator accepting US customers is not the same as an operator being authorized by a US state regulator to serve them. Offshore sites may accept sign-ups while falling outside US state consumer protections, which affects your options if a dispute arises.
• Sweepstakes and social casino models operate under different rules again, and their availability varies by state.

We describe what an operator states about its own licensing and flag where we could not verify it. We do not assert that any site holds a specific licence unless that is documented. And we never describe a casino as completely safe or guarantee that any withdrawal or win will be paid.

Gambling should not be a financial plan

Nothing on this site presents gambling as a way to make money or to solve a financial problem. The house edge means losses are the expected outcome over time. If play stops being entertainment, deposit and loss limits, time-outs and self-exclusion tools are available at licensed operators, and blocking software can restrict access at device level. Our responsible gambling guide sets out the US support services and the practical steps for using those tools.

Who writes this

Editorial work on Online Casino Sites is produced by our consumer editorial team, led by Madison Keller, who is responsible for the research standards described above and for the fact-check dates carried on each page. We correct errors when they are pointed out, and we date corrections.

Our terms and conditions cover the limits of the information published here. If you spot an out-of-date bonus term, a broken claim or something we have got wrong, send us the details — reader corrections are the fastest way we find problems. Readers researching options outside US-regulated markets may also find our coverage of casinos operating without GamStop restrictions useful for context on how different regulatory regimes handle self-exclusion, though the rules there do not apply to US players.

How to use this site well

Start with the offer type that suits how you actually play. If you want to try slots with limited exposure, weigh free spins packages on spin value and cashout caps rather than on the number of spins. If you dislike playthrough conditions, a smaller no-wagering offer may leave you better off than a large match. Then read the operator's own terms before depositing — ours is a starting point for comparison, not a substitute for the contract you agree to when you open an account.
