Terms and Conditions

These terms and conditions set out the rules for using Best Online Casinos at thornsmithlabs.com. They explain what this site is, what it is not, how our rankings and affiliate relationships work, and what you agree to when you read our pages or follow a link to an online casino. By using the site you accept them. If you do not, please stop using it.

Short version: we publish research-based comparisons of online casinos for readers in the United States. We do not take deposits, hold player funds, run games or settle disputes. Every operator sets its own terms, and those terms — not ours — govern your account.

Last reviewed: Sep 25, 2026. Terms, bonuses and state availability change frequently, so always read the operator's own conditions before you deposit.

Who may use this site

Best Online Casinos is intended for adults of legal gambling age in their jurisdiction. In most US states that is 21, though some set it at 18 for certain products. You must not use this site if you are below the applicable age where you are located.

Legal online casino play in the US is regulated state by state, not federally. A handful of states license and regulate real-money online casino gaming; many others permit only sports betting, lottery products or nothing at all. Separately, a number of operators run sweepstakes or social casino models that are available more widely but work differently from state-licensed real-money play, and are excluded in some states.

It is your responsibility to check what is lawful where you actually are, not where you are registered, and to comply with it. Nothing on this site is legal advice. We describe how licensing and regulation generally work in the US and what to verify; we do not certify that any operator is authorized to serve you in your state, and accepting US customers is not the same thing as being licensed to serve them.

How our rankings and editorial ratings work

The ordered list on our comparison pages reflects editorial judgment, not a laboratory test and not customer-review scores. We research public information: license and ownership details where they are published, the full bonus terms, stated payment methods, withdrawal limits and timings, game categories and software providers, support channels and responsible gambling tools.

We have not deposited, played or withdrawn at any operator listed here. Where we cite a speed, a bonus percentage or a limit, it comes from the operator's published material and is labeled as advertised, not verified by play. Editorial ratings — the numbers shown on the cards above — are our own summary scores on a ten-point scale, applied consistently across operators. They are opinions, not measurements, and not user ratings.

Commercial disclosure

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

Commission does not buy position. Ranking order and editorial ratings are set before commercial terms are considered, and a paying partner that fails on licensing transparency, bonus terms or complaint handling is marked down or left off. We also list operators we earn nothing from. Our full comparison of US online casinos explains the criteria in more detail, and our editorial approach covers who writes this site.

Bonus terms: what governs what

The headline offers shown on this site are summaries. The operator's own bonus terms are the binding document, and they override any description here. Before you claim anything, check these clauses, because they decide what the offer is actually worth:

• Wagering requirements — the multiple of bonus (or bonus plus deposit) you must stake before withdrawal. A 40x requirement on a $100 bonus means $4,000 in qualifying bets.
• Game weighting — slots usually count 100%, while blackjack, roulette and baccarat often count 10% or not at all. Live dealer tables are frequently excluded.
• Maximum bet while a bonus is active — often $5 or $10 per spin or hand. Exceeding it can void the bonus and any winnings from it.
• Cashout caps — a ceiling on what you can withdraw from bonus winnings, common on no-deposit offers and free spins.
• Expiry — bonus funds, free spins and the wagering window all have deadlines, sometimes as short as 24 hours for spins.
• Minimum deposit and excluded payment methods — some offers require a set deposit and disqualify certain e-wallets.

How the offers on this page differ

These are the advertised terms as published by each operator. Percentages and caps change without notice, and eligibility depends on your state.

Three listings and the terms attached to them

Raging Bull — the largest headline cap, and the longest small print

Raging Bull sits at the top of our list because the advertised package — 410% up to $10,000 plus 50 free spins — is the widest headline on this page, and the operator publishes its bonus conditions in enough detail to be assessed rather than guessed at. For a reader comparing match percentages, it is the obvious reference point.

The limitation is proportionate to the size. A four-figure match is only reachable with a very large deposit, and large matches typically carry high playthrough, tight maximum bets and restricted game lists. The realistic value for a $50 depositor is nothing like the headline. Read the wagering multiple, the per-spin cap and the withdrawal limits before treating the $10,000 figure as meaningful.

Magician Bet — no wagering, smaller number

Magician Bet's 101% no-wagering offer is here because it inverts the usual trade-off. If the terms hold, winnings from the bonus are withdrawable without playthrough, which removes the single clause that most often turns a bonus into a dead end. For readers who dislike rollover arithmetic, that matters more than a bigger percentage.

The drawback is scale and scope. A 101% match is modest beside the triple-digit offers around it, no-wagering deals usually come with a firm maximum bonus amount, and "no wagering" does not always mean no conditions — expiry, minimum deposit and excluded games can still apply. Confirm the cap and the deadline.

Slots of Vegas — a spins offer tied to one game

Slots of Vegas earns its place for a clearly specified package: a 375% match plus 50 free spins named to a particular title, Cash Chaser. Specificity is useful, because you can see exactly where the spins are usable rather than discovering an exclusion list later.

That specificity is also the limitation. Spins locked to a single slot suit you only if that game's volatility and RTP suit you, and single-title spins frequently carry a cap on winnings. If you prefer table games or live dealer play, most of this offer's value is unavailable to you.

Money: what it costs you, and what it costs us

Using Best Online Casinos is free. We charge readers nothing and never ask for payment details. Our revenue comes from the affiliate arrangements described above.

Money only changes hands at the operator. We do not process deposits or withdrawals, hold balances or issue refunds, and we cannot release a payout. Payment terms vary by operator and by state, so treat the following as what to check rather than what any listed site offers:

• Debit cards — the most widely accepted deposit route at US-facing casinos, usually instant, sometimes with a small processing fee.
• Credit cards — accepted by some operators and blocked by some issuers, who may treat the transaction as a cash advance with interest from day one.
• ACH and online banking transfers — common for both directions; deposits often same-day, withdrawals typically a few business days.
• Wire transfers — used for larger withdrawals, generally the slowest and the most likely to carry a bank fee.
• E-wallets — fast where supported, but PayPal and similar services are available only at certain regulated operators and in certain states; never assume.
• Prepaid cards and cash-at-cage — deposit-only in many cases, and rarely usable for payouts.
• Cryptocurrency — offered by some offshore-facing sites, as with the Bets.FM offer above. Value moves between deposit and withdrawal, and chargeback protection does not exist.

Minimum deposits commonly start around $10 to $20. Minimum withdrawals are usually higher, and monthly withdrawal limits are the detail most often missed: a site can advertise fast payouts while capping weekly releases at a few thousand dollars, which turns a large win into an installment plan. Check the cap, the fee per withdrawal and how many free withdrawals you get per month.

Verification and withdrawal holds

Expect identity verification before your first payout. Operators request photo ID, proof of address and proof of the payment method, and may run source-of-funds checks on larger amounts. This is standard anti-money-laundering practice, not an obstruction, but it delays withdrawals if you leave it until you have a balance waiting. Upload documents early, use your own name on every account, and keep the deposit and withdrawal method consistent.

If a payout is refused or stalled, the operator's complaints procedure comes first, then any regulator or dispute service named in its terms. We are not a party to your account and cannot intervene, though we do want to hear about it — you can tell us what happened and it informs our coverage.

What you will find at the operators we cover

We describe game ranges in general categories rather than counts, because catalogs change weekly:

• Slots — the bulk of most libraries, from low-volatility classics to high-variance releases. RTP and volatility are published by the studio and are worth checking; they describe long-run behavior, not your session.
• Progressive jackpots — pooled prizes that grow until won. Some require a maximum bet to qualify, and jackpot wins are often paid in installments under separate terms.
• Table games — blackjack, roulette and baccarat, usually in multiple rule variants. These are the games most likely to be weighted low or excluded from bonus playthrough.
• Live dealer — streamed tables with human croupiers, higher minimum stakes and, at most operators, no bonus eligibility at all.
• Mobile play — browser-based at most sites, with native apps at some. Feature parity is not guaranteed; live dealer and some payment options occasionally differ on mobile.

Outcomes at licensed operators are produced by random number generators, tested by independent labs where the regulator requires it. No sequence of results is due, and no strategy changes a slot's built-in edge.

Other products at the same brands

Several operators listed here run more than a casino, and the terms are not shared. BetUS, for example, is a sportsbook as well as a casino, and sports wagering usually has its own rollover rules, its own maximum bets and its own bonus balance. A casino bonus rarely clears through sports bets, and mixing the two is a common way to void an offer.

Others operate on a sweepstakes model — Zumba Cards and Amazon Jackpots advertise offers denominated in SC rather than dollars. Sweepstakes coins are redeemed under promotional rules, with their own minimum redemption thresholds and eligibility conditions, and the state exclusions differ from real-money casino play. Poker rooms, bingo and racebooks appear at some brands too. Read each product's terms separately; the welcome offer you accepted covers one of them.

Accuracy, liability and changes to these terms

• We publish in good faith and correct errors when we find them, but offers, terms, payment options and state availability change without notice. The operator's live terms take precedence over anything written here.
• Nothing on this site is financial, legal or tax advice, and no content should be read as a prediction of results. Gambling is entertainment with a built-in house edge and is not a way to make money or address debt.
• We describe player protections; we never describe any operator as completely safe, and we cannot guarantee that any withdrawal will be paid.
• To the extent permitted by law, Best Online Casinos is not liable for losses arising from your use of a third-party operator. Your contract is with them.
• Site text, ratings and layout are our property. You may quote short extracts with attribution and a link; wholesale reproduction is not permitted.
• We may update these terms. The review date at the top shows when they were last checked. Continued use means you accept the current version.

Playing within limits

Licensed operators are required to offer deposit limits, loss limits, session reminders, cooling-off periods and self-exclusion. Set them when you open the account, not after a bad week — most take effect immediately and are deliberately slow to reverse. Blocking software on your phone and computer is a useful second layer.

If gambling has stopped being entertainment, free confidential help is available in the US through the National Council on Problem Gambling helpline on 1-800-522-4700, which operates 24 hours a day. Our responsible gambling guide covers the tools in more detail, including state self-exclusion registers.

Questions about these terms

If something here is unclear, if you believe a figure on this site is out of date, or if you want to know how a particular ranking was reached, write to us through the contact page. We answer questions about our own methods and coverage. Questions about your account, your balance or a pending payout have to go to the operator — they hold the funds and the records, and they are the only party who can act on them.
