About Us
Online Casino Sites is an independent research desk covering US online casinos, with a particular focus on free spins and the bonus terms attached to them. This page explains who writes the content, how casinos are assessed, how the site earns money, and what our ratings do and do not mean — so you can judge our comparisons the same way we ask you to judge a bonus.
The short version: we read terms and conditions so you don't have to. Free spins are the most commonly advertised and most commonly misunderstood promotion in online gambling, so most of our work sits there — wagering requirements, spin values, game restrictions, expiry windows and cashout caps.
Who writes this site
Editorial work is led by Logan Hughes, who researches and maintains the casino reviews, bonus breakdowns and comparison pages published here. Pages carry a last-updated date, and the factual review behind this one was completed on Sep 25, 2026. Where a promotion, payment method or state availability detail has a shelf life, we date it in the text rather than letting it quietly age.
We are a publisher, not an operator. We do not take deposits, hold player funds, run games or process withdrawals. If you have an account dispute, it is resolved between you, the casino and the relevant regulator — we can only explain the process, and our contact page is open if you want to tell us what happened so we can factor it into a review.
How we make money, stated plainly
Some links on this site are commercial. If you follow one, open an account and deposit, the publisher may receive a commission from the casino. That arrangement funds the research.
It does not buy a position. Commission rates are not an input into our scoring, and brands cannot pay to be added, moved up or have a limitation removed from their write-up. Where a rating is high and the offer still has a catch, we say so. A rating on this site is an editorial score set by us — it is not a customer-review average, and it is not a prediction of how you personally will get on.
What we actually check
There is no testing claim here. We have not deposited, played or withdrawn on your behalf. What we do is read published terms, license and ownership information, banking pages and help centers, then compare what the advertising says against what the small print allows. For free spins specifically, that means:
- Wagering requirement — the multiple of winnings (or bonus plus deposit) you must bet before a withdrawal is possible. A 40x requirement on $20 of spin winnings means $800 in qualifying bets.
- Spin value — 50 free spins at $0.10 is $5 of play, not a headline figure.
- Game restriction — spins are usually locked to named slots, and contribution rates differ by game type.
- Maximum bonus bet — often $5 or lower; exceeding it can void winnings outright.
- Expiry — spins and any bonus balance typically lapse within days.
- Cashout cap — a ceiling on what converts to withdrawable cash, common on no-deposit offers.
- Identity verification — KYC documents are requested before a first withdrawal, not before a deposit.
Three of the listings, and why they sit where they do
The ranked cards above are generated from our current selections. Below are notes on the top entries, including what we consider the weak point of each. Every offer quoted is the advertised headline as published by the operator; terms decide what it is worth.
Raging Bull — rated 10.0
It leads the list because the headline combines a large percentage match with a free spins component: 410% up to $10,000 + 50 Free Spins. For a free-spins-focused reader, the spins are the part to interrogate — their per-spin value, the slot they are tied to and the playthrough attached to any winnings all sit in the promotion terms rather than the banner. The limitation is structural: percentage matches of this size almost always carry heavy wagering and a maximum bet rule, and the $10,000 ceiling is only reachable with a deposit most readers will never make. Treat the top line as the maximum theoretical case, not the typical one.
Magician Bet — rated 9.8
Listed for a different reason entirely. The advertised 101% No Wagering offer removes the mechanic that makes most spin and match bonuses hard to convert. If the no-wagering description holds in the full terms, winnings are cash rather than a locked bonus balance — which is the single biggest improvement a promotion can make. The trade-off is scale: no-wagering offers are usually smaller and more tightly capped than heavily wagered ones, and "no wagering" sometimes still sits alongside a maximum conversion limit or a qualifying deposit minimum. Read the cap before assuming the whole balance is yours.
Slots of Vegas — rated 9.8
Here the spins are named rather than vague: 375% Bonus + 50 Free Spins on Cash Chaser. A specified game is useful, because you can check that title's RTP and volatility before you decide whether 50 spins is a realistic route to anything. The drawback is the flip side of the same fact — the spins are not transferable to a slot you prefer, and a single-title restriction narrows your options if the game's volatility doesn't suit you. As with any large percentage match, the bonus portion will carry playthrough that the 375% figure does not mention.
The rest of the list at a glance
| Casino | Advertised offer | Editorial rating | Free spins included |
|---|---|---|---|
| Uptown Aces | 600% for new players | 9.5 | Not stated in headline |
| Card Crush | Instant welcome reward: 2 mystery coins & 5 cards | 9.5 | No — card-based reward |
| Zumba Cards | 250% deposit bonus up to 250 SC | 9.5 | Not stated in headline |
| BetUS | 200% up to $4,000 for new players | 9.3 | Not stated in headline |
| Amazon Jackpots | 4 posters + 40 free SC + bonus wheel for $20 | 9.2 | No — SC package, requires $20 purchase |
| Slots and Casino | 500% up to $2,500 x3 | 9.2 | Not stated in headline |
| Bets.FM | 225% deposit bonus up to 1 BTC + 225 free spins | 8.9 | Yes — 225 spins advertised |
Two things worth noting from that table. Offers quoted in SC belong to sweepstakes-style sites, where the currency is a promotional credit rather than a dollar balance, and redemption rules differ from a cash casino. Offers quoted in BTC are crypto-denominated, which brings exchange-rate movement and network fees into the picture. Neither is better or worse by default, but they are not directly comparable to a dollar match.
How deposits, bonuses and withdrawals work in practice
Nothing on this site costs you anything to read. The cost sits at the casino, and it is worth understanding before a free spins offer tempts you into a deposit.
- Minimum deposits commonly start around $10–$25 depending on the operator and method, and some promotions set a higher qualifying minimum than the site's general floor.
- Paying in is typically by debit card, credit card (frequently declined by US issuers for gambling), ACH bank transfer, wire, e-wallets where offered, prepaid cards and, at some sites, cryptocurrency. PayPal appears only at certain state-licensed operators and is not universal.
- Getting paid out often uses fewer methods than paying in. ACH and bank wire are the common routes; card refunds and e-wallet payouts depend on the site. Expect a minimum withdrawal figure, a weekly or monthly limit, and possible fees on wires.
- Timing splits into two parts: the operator's internal review — sometimes a pending or reversal window — and then the banking leg. Advertised speeds are marketing claims, not results we have measured.
- Verification comes before your first cashout. Photo ID, proof of address and sometimes proof of the payment instrument. Larger or unusual activity can trigger source-of-funds questions. Uploading documents early is the simplest way to avoid a delay later.
A free spins win does not become withdrawable money until the attached wagering is complete, the bonus has not expired, no maximum bet rule was breached and verification has cleared. No site can guarantee a payout, and we never suggest otherwise.
What the casinos on this site actually offer
Beyond the welcome offer, the libraries we look at generally break into a few categories:
- Slots — the home of free spins. Worth checking RTP and volatility, both of which are published by the software provider rather than invented by the casino.
- Progressive jackpots — pooled prizes that grow across play; frequently excluded from bonus wagering.
- Table games — blackjack, roulette, baccarat and poker variants, usually contributing little or nothing toward playthrough.
- Live dealer rooms — real tables streamed in real time, almost always outside free spins eligibility.
- Instant win and card formats — the basis of the coin and card rewards on sites like Card Crush and Zumba Cards.
- Mobile play — browser-based at most sites, with native apps where an operator is state-licensed. Game outcomes come from random number generators, tested by independent labs at licensed operators.
The other products these brands run
Several operators on this list are not casino-only. BetUS and Bets.FM sit alongside sportsbook operations, where the money works differently: you back an outcome at fixed odds, there is no RTP figure, and bonus terms are expressed as rollover on stakes rather than spins. Sportsbook promotions rarely combine with casino ones, and a free bet is not a free spin. Sweepstakes-style brands such as Zumba Cards and Amazon Jackpots run coin-package purchases and social-play features rather than conventional deposits. Read whichever set of terms applies to the wallet you are actually using — they are usually separate documents.
Legal standing and who can play
US online gambling is regulated state by state, not nationally. Federal law shapes the framework, but the authorization to offer real-money online casino games comes from a state regulator, and only a minority of states license them. That means a site accepting a signup from your address is not the same thing as a site being authorized to serve your state — those are two different questions, and only the second one gives you a regulator to complain to.
Before depositing anywhere, check three things: that the operator names a licensing authority and license number you can verify with that regulator; that your state is genuinely covered; and that you meet the age requirement, which is 21 or over at most US casino operators and never below 18. Sweepstakes models operate under different legal reasoning again, with their own state exclusions.
At a state-licensed operator you should expect a published complaints procedure, an escalation route to the regulator, and mandatory player-protection tools: deposit and loss limits, session reminders, cooling-off periods and self-exclusion. Our responsible gambling guide covers those tools, plus blocking software and the national support lines, in more detail. Gambling is entertainment with a cost attached, not a way to make money or fix a financial problem — if it stops feeling like the former, the limits and exclusion options exist for exactly that moment.
Corrections, disputes and what to do next
We get things wrong sometimes, and promotions change without notice. If an offer on this site no longer matches what the casino publishes, tell us and we will check it. The same applies if you think a rating is too generous. Reader reports of withdrawal delays and voided bonuses are the most useful thing we receive, because they point us at the terms worth re-reading.
If you are here to compare free spins rather than to compare publishers: start with the wagering requirement, then the spin value, then the expiry. An offer with a smaller headline and no playthrough is frequently worth more than a four-figure match you cannot clear. Our terms of use set out the limits of the information published here, and the contact form is the fastest way to reach the desk.
