About Us
Best Online Casinos is a research-led comparison site covering online casinos available to players in the United States, with a particular focus on free spins and the bonus terms attached to them. This page explains who writes the site, how the rankings are put together, how we pay for the work, and what our coverage does and does not claim.
The short version: we read terms and conditions so you don't have to open twelve tabs at once. A free spins offer is only as good as its wagering requirement, its maximum bet rule, its expiry window and its cashout cap — and those four details are where most readers get caught out.
How we make money, and what that does not buy
Some of the links on redswoosh.net are commercial. If you follow one and open an account, the operator may pay us a commission. That is how the site is funded, and we would rather say it plainly than bury it.
What commission does not do is decide order. Editorial ratings are set by our own scoring, applied the same way to every brand, and a partner that scores poorly on bonus terms or withdrawal conditions ranks below one that scores well. Our ratings are editorial judgments, not customer-review scores, and they are not a prediction of how any individual account will go.
What we assess before a casino appears on a list
We do not gamble with our own money to produce these reviews, and we do not claim to have tested payouts. Everything here comes from published terms, operator documentation, regulator and state-authority material, and ongoing monitoring of how offers change. Where a fact could not be verified, we say so rather than filling the gap.
- Bonus terms in full. Wagering requirements, game weighting, maximum bonus bets, expiry dates and cashout limits on free spins and deposit bonuses.
- Payments. Minimum deposits, minimum withdrawal amounts, withdrawal limits, stated processing times and any fees.
- Verification. How KYC and identity checks are handled, when source-of-funds checks are triggered, and what documents are requested before a withdrawal clears.
- Licensing and availability. Which authority the operator answers to and which US states it says it serves.
- Games and software. Slots, table games, live dealer rooms, the studios behind them, published RTP information and whether outcomes are driven by certified random number generators.
- Support and player protection. Contact channels, complaints procedures, deposit and loss limits, self-exclusion tools.
Findings are dated. Our most recent full fact-check pass was completed Sep 25, 2026, and offers change without notice — always confirm the current terms on the operator's own page before depositing.
Free spins: the four numbers we always dig out
Free spins are the headline on most welcome packages, so they get the most scrutiny here. The advertised spin count tells you almost nothing on its own. These do:
- Wagering requirement. How many times the winnings from spins must be staked before withdrawal. A 40x requirement on $20 of spin winnings means $800 in qualifying bets.
- Maximum bonus bet. Many operators cap stakes while a bonus is active, often around a few dollars per spin. Exceeding it can void the balance.
- Expiry. Spins and the winnings they produce usually run on separate clocks, sometimes as short as 24 hours for the spins themselves.
- Cashout cap. A maximum amount you can withdraw from spin winnings, regardless of how well the round goes.
We also flag no-wagering offers, because they remove the first of those four problems entirely — usually in exchange for a smaller headline number.
Examples of how our write-ups read
A few of the brands currently on our lists, to show the level of detail we aim for. Offers below are as advertised by the operator; conditions apply and are set by the casino, not by us.
Raging Bull — editorial rating 10.0
It sits at the top because its advertised welcome package, 410% up to $10,000 plus 50 free spins, combines a very large match ceiling with a spins component, and its bonus documentation is detailed enough to check line by line. That matters more than the percentage: a 410% match is only reachable with a substantial deposit, and the $10,000 figure is a cap, not an expectation. Limitation: large percentage matches of this kind typically carry high playthrough and restricted game weighting, so the practical value is far below the advertised maximum for anyone depositing a modest amount.
Magician Bet — editorial rating 9.9
Included because of the structure rather than the size. A 101% no-wagering offer means bonus funds are not locked behind a playthrough multiple — the single most common reason readers tell us a withdrawal was refused. For players who want a clean balance rather than a big number, this is the more honest shape of offer. Limitation: no-wagering deals almost always come with tighter maximum bonus amounts and shorter windows than high-percentage matches, and there is no free spins element in the headline.
Slots of Vegas — editorial rating 9.6
Here for the spins specifically: 375% bonus plus 50 free spins on Cash Chaser. Game-specific spins are easier to evaluate than open spins, because you can check a single title's volatility and published RTP before deciding whether the round is worth taking. Limitation: spins tied to one game cannot be moved, so if that title's style does not suit you, the spins portion is effectively wasted value.
Uptown Aces — editorial rating 9.6
Listed for the highest advertised match rate on our table, 600% for new players. High-multiple offers suit small deposits better than they look, since the match scales the deposit rather than the cap. Limitation: the headline does not state a dollar ceiling, and offers of this size generally carry the strictest maximum bet rules, so the terms page needs reading before you commit.

Money in, money out: what we check on costs
Taking part costs whatever you deposit — bonus percentages are applied to your own money, so nothing on this site is free in the sense of costing nothing. Where an offer requires a qualifying spend, such as Amazon Jackpots' $20 bundle, we state that beside the offer rather than in a footnote.
On payments, availability for US players varies by operator and by state, so we verify rather than assume. The methods you are most likely to encounter are debit cards, credit cards (some issuers decline gambling transactions outright), ACH and online bank transfers, wire transfers for larger sums, prepaid cards, and e-wallets including PayPal where the operator and your state both support it. Crypto appears at some brands — Bets.FM quotes its bonus cap in bitcoin, for example.
Four things decide whether a payment method is actually good for you: whether deposits and withdrawals both use it, the minimum and maximum per transaction, how long the operator says payouts take once approved, and whether a fee is charged at either end. Withdrawal times published by casinos are advertised estimates, not measured results — we report them as claims. Expect a review period before funds are released, and expect identity verification to be completed first.
What the casinos on this site actually offer
- Slots. The bulk of most libraries, and where free spins are nearly always spent. Worth checking published RTP and volatility: a high-volatility title burns through spins faster but pays larger, less often.
- Progressive jackpots. Pooled prizes that grow until won. Frequently excluded from bonus play or weighted at zero toward wagering.
- Table games. Blackjack, roulette and baccarat. Usually contribute little or nothing to wagering requirements.
- Live dealer rooms. Real dealers streamed in real time, mostly blackjack, roulette and baccarat variants, typically excluded from free spins offers entirely.
- Sweepstakes and social formats. Brands like Zumba Cards and Amazon Jackpots use coin-based currencies such as SC rather than direct cash play, which changes both eligibility and how redemptions work.
- Mobile. Browser play is near-universal; dedicated mobile apps are not. We note which is which rather than assuming an app exists.
The other products these operators run
Several brands we cover are not casino-only. BetUS, for instance, operates sportsbook and racebook products alongside its casino, and its welcome offers may be split or restricted by product. This matters for bonus terms: sports wagers often do not count toward casino playthrough, and a single bonus balance may be ring-fenced to one section of the site. Poker rooms, bingo and virtual sports also appear at some operators. If you plan to use more than one product, check whether the bonus follows you across them — usually it does not.
Legal standing, eligibility and player protection in the US
Online casino law in the United States is decided mainly at state level. Federal law shapes some elements, notably around interstate wire transmission and payment processing, but whether you may legally play real-money online casino games depends on the state you are physically in at the time. Only a minority of states license and regulate online casino play; several more permit online sports betting but not casino. Sweepstakes and social casino models operate under a different legal framework again, and are restricted or excluded in some states.
Accepting sign-ups from US residents is not the same thing as being authorized to serve them. We report what an operator states about its licensing and state availability, and we do not assert a licence we cannot verify. Before depositing, check your own state's position and the operator's terms for your state.
Practical eligibility basics: you must be at least 21 in most regulated US casino markets (18 in a small number of jurisdictions and for some product types), you must use your own identity and payment methods, and you will need to pass identity verification before a withdrawal is released. Documents commonly requested include photo ID, proof of address and proof of payment ownership; larger or unusual balances can trigger source-of-funds checks. Gambling winnings are generally taxable income in the US — a tax professional, not a comparison site, is the right source on that.
If a withdrawal is delayed or refused, the operator's own complaints procedure is the first step, in writing, with your account ID and dates. If that fails, escalate to the licensing authority named in the operator's terms. Keep records throughout.
Playing within limits
No casino is completely safe, no withdrawal is guaranteed and gambling is not a way to make money or fix a financial problem. The house edge is built into every game on every site we cover. Deposit limits, loss limits, session reminders, cooling-off periods, self-exclusion and third-party blocking software are all worth setting up before you need them rather than after. Our responsible gambling guidance covers the tools available and where to find free, confidential support in the US.
Who writes this and how to reach us
Editorial work on Best Online Casinos is led by Brooke Stone, who sets the review framework and signs off ranking changes. Pages carry an updated date so you can see how current the research is, and time-sensitive findings are dated in the text.
If you spot something out of date, disagree with a rating, or want to tell us how a withdrawal actually went, we want to hear it — reader reports are one of the main reasons we re-check a brand. Use the contact page to get in touch. Our terms and conditions set out how the site may be used, and readers outside the US may find our non-GamStop casino coverage more relevant to their market.
The best way to use this site is to start with the bonus terms rather than the headline percentage, narrow to two or three brands that pay by a method available in your state, then read the operator's own terms before you deposit. Take your time — the offers will still be there tomorrow, and the ones that won't were never worth rushing for.
