Terms and Conditions | Best Online Casinos

These terms and conditions set out the rules for using Best Online Casinos at oh-trina.com. Read them before you rely on anything published here. In short: this is an independent comparison and information site about US online casinos, not a gambling operator. We do not accept deposits, hold funds, run games or pay winnings. When you click through to a casino, your relationship is with that operator, under that operator's own terms and conditions — which always override ours.

By browsing the site you accept the terms below. If you do not accept them, please stop using the site. This page was last checked for accuracy on Sep 25, 2026 and may be updated without individual notice; continued use after a change means you accept the revised version.

Who may use this site

You must be at least 21 years old to use oh-trina.com. Real-money online casino gambling in the United States is regulated state by state, and the minimum age in the states that license it is generally 21, with a small number of gambling activities permitted at 18. We apply 21 as the site-wide threshold.

You confirm you are of legal age in the state you are physically located in.
You confirm that using an online casino is lawful where you are. Legal availability varies by state, and being able to reach a website is not the same as being allowed to play from your location.
You are responsible for checking your own state's position before depositing anywhere.
Nothing on this site is legal advice, financial advice or tax advice.

Legal standing, licensing and what we can and cannot tell you

There is no single federal license for online casinos in the US. Federal law shapes the framework — the Wire Act, UIGEA and related statutes affect how payments and interstate transmissions work — but the decision to authorize and license online casino play is made at state level. A handful of states license real-money internet casinos and run their own regulators; many more permit only sports betting, lottery products or nothing at all. Separately, sweepstakes and social casino sites operate under promotional-sweepstakes law rather than gaming licenses, and their legality also varies by state.

What follows from that for you as a reader:

An operator accepting US customers is not the same as an operator being authorized to serve customers in your state. Treat those as two different questions.
We do not assert the licensing status of any brand listed here unless we have verified it, and we will say so where we have. Where we have not, assume the question is open and check the operator's own footer, license number and terms.
Player protections — dispute escalation, segregated funds, advertising rules, self-exclusion registries — exist only where a state regulator imposes them. Offshore and sweepstakes sites may offer fewer or different remedies.
If a listing is unavailable in your state, the operator, not this site, is the party that enforces that.

Some brands on this site use virtual currency or sweeps-coin models rather than direct cash wagering. Zumba Cards advertises its bonus in SC (Sweeps Coins) and Amazon Jackpots advertises free SC with a purchase, which indicates a sweepstakes structure rather than a state-licensed cash casino. Bets.FM advertises its bonus in bitcoin, which carries its own conversion and volatility considerations. These are different products with different rules, and we flag the distinction rather than blurring it.

Commercial disclosure: how we make money

Best Online Casinos earns revenue through affiliate arrangements. If you follow a link from this site to a casino and open an account, we may receive a commission from that operator. You pay nothing extra, and the offer you see is the offer the operator publishes.

Commission does not buy position. Our editorial ratings are set by the research team and are not for sale, not negotiable and not adjusted in exchange for higher payouts. Operators cannot review copy before publication. We also list brands we hold no commercial relationship with where they are relevant to a comparison, and we will state a limitation of a top-ranked brand as readily as one further down.

Our ratings are editorial scores produced by us. They are not customer-review averages, they are not a measure of how likely you are to win, and they are not a safety guarantee. No online casino is completely safe, and we will never describe one that way.

How bonus listings are presented — and what the terms behind them mean

Every headline offer shown on this site is the operator's own advertised figure, reproduced as advertised. Bonus terms change frequently and without notice. The operator's current terms page is the authoritative source; ours is a signpost.

Because this site's focus is the size of the bonus, it is worth being blunt about what a large percentage does and does not mean. A 600% match is not 600% of value. The conditions attached decide that, and the conditions you should read before claiming anything are:

Wagering requirements — the multiple of the bonus, or bonus plus deposit, you must stake before withdrawal. A $100 bonus at 40x means $4,000 in wagers.
Maximum bonus bet — a per-spin or per-hand cap, often $5 or $10, while bonus funds are active. Breaching it can void the bonus and any winnings from it.
Bonus cashout limits — a cap on what you can withdraw from bonus play, frequently expressed as a multiple of the deposit. Large-percentage offers often carry the tightest caps.
Expiry dates — bonus funds and free spins usually expire, often within 7 to 30 days.
Game weighting — slots typically contribute 100%, while blackjack, roulette, baccarat and live dealer tables contribute far less or nothing.
Minimum deposit — the amount needed to trigger the offer, which is rarely the amount needed to reach the maximum advertised figure.

For a fuller treatment of how these interact, see our guide to the casinos with the biggest bonuses.

Three listings and why they appear as they do

Raging Bull — the largest headline ceiling on the list

Raging Bull sits at the top of our ratings because its advertised 410% match up to $10,000 plus 50 free spins is the highest nominal ceiling among the brands we cover, and because it presents a conventional slots-led real-money model rather than a virtual-currency one. That makes it the clearest reference point for readers comparing raw bonus size.

Limitation: a ceiling that high is realistic only for very large deposits, and high-percentage matches of this type customarily attach heavy wagering and a cap on withdrawable bonus winnings. Verify both figures in the operator's terms before treating $10,000 as an achievable number. We have not verified its licensing position with a US state regulator.

Magician Bet — the offer built around the absence of wagering

Magician Bet is here for a different reason: its 101% no-wagering offer trades headline size for simplicity. If a bonus genuinely carries no playthrough, winnings from it behave like cash, which for many readers is worth more than a larger number with 40x attached.

Limitation: the advertised figure gives no maximum bonus value, so the real size is unknown until you read the terms. No-wagering offers commonly compensate with low caps, short expiry windows or excluded deposit methods. Confirm the maximum and the expiry before you commit.

Uptown Aces — the highest match percentage published

Uptown Aces advertises 600% for new players, the biggest percentage on this page, which makes it the obvious test case for the point we keep making: percentage and value are not the same thing. It suits readers depositing small amounts who want maximum bonus balance to play with.

Limitation: no maximum dollar figure is published in the headline, and offers structured this way typically carry a firm cashout limit expressed as a multiple of the deposit. Treat it as extended play time rather than a route to a large withdrawal, and check the max bet rule carefully.

Money, payments and what the operator controls

All deposits, withdrawals, fees and limits are handled by the casino, not by us. We accept no responsibility for transactions, delays, declined payments or disputed balances. Still, these are the mechanics you should confirm on the operator's banking page before depositing:

Cost to take part. Most welcome offers require a qualifying deposit — typically a published minimum such as $10, $20 or $25. Nothing requiring a deposit or purchase is free, and we do not describe it as such. The Amazon Jackpots listing above is explicitly tied to a $20 purchase.
Debit cards — the most widely accepted method at US-facing casinos. Deposits are usually instant; some issuers decline gambling transactions.
Credit cards — accepted by some operators and blocked by some banks. Card issuers may treat the transaction as a cash advance with its own interest and fee.
ACH and online bank transfer — common in state-regulated markets, slower than cards, usually low or no fee.
Wire transfer — used for larger withdrawals, often with a bank fee and a multi-day timeline.
E-wallets — availability varies. PayPal is generally limited to operators licensed in the state you are playing from, and is not a given at offshore or sweepstakes sites.
Cryptocurrency — offered by some brands, including the bitcoin-denominated offer listed above. Values move, and conversions at deposit and withdrawal can change what you actually receive.
Prepaid cards and cash at cage — sometimes available for deposit only.

Withdrawal timings, minimum withdrawal amounts, weekly or monthly payout caps and processing fees are set by each operator and differ by method. Expect a first-withdrawal delay for KYC. Verify each figure on the operator's own site; we do not publish payout speeds we have not confirmed.

Verification you should expect

Identity check (KYC): government photo ID, plus proof of address such as a utility bill or bank statement.
Payment ownership: a card image or account statement confirming the method is yours.
Source-of-funds checks on larger or unusual activity, which may require pay stubs or bank records.
Release of funds once checks clear, to the original deposit method where the operator's policy requires it.

If a withdrawal is refused or stalled, raise a complaint with the operator first and keep written records. Where the operator is licensed by a state regulator, escalation to that regulator is available. Where it is not, your remedies may be limited to the operator's own internal process. We cannot intervene in, arbitrate or resolve disputes between you and a casino.

What the sites we cover actually offer

Listings on oh-trina.com span several game categories, and bonus terms treat them very differently:

Slots — the bulk of most libraries, and usually the only category that contributes 100% toward wagering. RTP and volatility vary by title; high-volatility games swing harder, which matters when a max bet rule is in force.
Progressive jackpots — pooled prizes that grow until won. Frequently excluded from bonus play or capped.
Table games — blackjack, roulette and baccarat. Low or zero wagering contribution at most operators.
Live dealer — human-dealt tables streamed in real time, usually excluded from welcome bonus playthrough.
Specialty and card formats — keno, scratch products and the card-based games behind brands such as Card Crush and Zumba Cards.

Game fairness in licensed environments rests on random number generators tested by independent labs. We report RTP figures only as published by the operator or the software provider, never as something we have measured.

Sportsbook and other product lines

Several brands listed here run more than a casino. BetUS operates a sportsbook alongside its casino, and offers of that kind often split rollover requirements between the two products or restrict which one the bonus can be used in — check whether a casino bonus can be cleared on sports wagers at all, since the answer is usually no. Bets.FM likewise presents itself across betting and casino play. Sweepstakes brands such as Amazon Jackpots and Zumba Cards sit outside both categories: you buy or collect a virtual currency and may redeem it under promotional rules rather than placing a cash wager. Our coverage on this site is casino-first; where a sportsbook, poker room or racebook affects a bonus term, we say so, but we do not review those products in depth.

Accuracy, content and liability

We research and verify. We do not gamble on readers' behalf, and nothing here is presented as the result of depositing, playing or withdrawing.
Offers, terms, ratings and availability change. Information is provided as-is and may be out of date by the time you read it.
We distinguish confirmed facts from operator advertising. Headline bonus figures are advertising, reproduced as published.
To the fullest extent permitted by law, Best Online Casinos accepts no liability for losses arising from gambling, from reliance on information here, or from your dealings with any third-party operator.
Site content, structure and ratings are our intellectual property. You may quote briefly with attribution; systematic copying or republication is not permitted.

Gambling responsibly

Gambling is entertainment with a cost, not a source of income and not a way to solve money problems. The house holds a mathematical edge on every game covered here. Set deposit and loss limits before you start, use cooling-off and self-exclusion tools where the operator provides them, and consider blocking software if you want a harder barrier. Our responsible gambling resources explain the tools available and where confidential help can be found. If gambling is causing harm to you or someone close to you, the National Council on Problem Gambling helpline, 1-800-GAMBLER, is available 24/7 in the US.

Changes, contact and governing terms

We may amend these terms at any time, and the version published at oh-trina.com is the one that applies. Where an operator's terms and ours differ on anything relating to your account, deposit, bonus or withdrawal, the operator's terms govern. If part of this page is found unenforceable, the rest continues to apply.

Questions about these terms, a correction to flag, or a listing you believe is wrong: reach us through the contact page. Background on who publishes this site and how ratings are produced is on the about page. We read everything sent to us, and corrections are made on the record.
