About Us
Online Casinos is an independent research site for people comparing online casinos available to US players. We built this page because "who's behind the ratings" matters just as much as the ratings themselves — so here's exactly what we do, how we do it, and where our money comes from.
We don't operate a casino, hold player funds, or process bets. We research licensed operators, read their bonus terms line by line, and compare what they offer against each other so you don't have to open ten tabs to work out which welcome package is actually worth claiming.
Why Free Spins Get Special Attention Here
Free spins are one of the most misunderstood parts of a casino welcome offer. A headline number like "50 Free Spins" or "20 Free Spins on Gorilla Slot" tells you almost nothing on its own — what decides whether it's worth claiming is the wagering requirement attached, which games the spins are restricted to, the maximum cashout cap, and the expiry window. We focus our comparisons on those conditions because that's where offers that look similar on the surface end up very different in practice.
How We Assess Each Operator
Every casino listed on this site is reviewed against the same set of criteria, applied consistently. Commission does not buy position — an operator paying a higher affiliate rate does not move up the rankings, and we say so plainly where an offer has a catch worth knowing about.
- Licensing and regulation — we check who licenses the operator and treat unlicensed or ambiguous sites as a reason to look elsewhere
- Bonus terms, not just headline offers — wagering requirements, game restrictions, maximum bet limits while wagering, expiry dates, and withdrawal caps on bonus winnings
- Banking — which deposit and withdrawal methods are actually supported for US players, and how long payouts typically take
- Game fairness — whether the operator publishes RTP information and relies on certified random number generators for its slot and table titles
- Security basics — HTTPS encryption, account verification steps, and how identity checks (KYC) are handled before a withdrawal is released
- Support quality — the channels on offer and how easy it is to reach a real answer
A Look at How the Top-Rated Sites Compare
These are the operators currently featured on this site, ranked by our editorial assessment. Each has a genuine limitation worth knowing before you sign up.
| Casino | Headline Offer | What to Check First |
|---|---|---|
| Raging Bull | 410% up to $10,000 + 50 Free Spins | Large percentage matches usually carry higher wagering requirements — confirm the multiplier and any per-game restrictions before depositing |
| Ignition | 300% Welcome Bonus up to $3,000 | Check which game categories count toward wagering, since poker and table games are often weighted differently than slots |
| Uptown Aces | 600% For New Players | A high match percentage on a smaller deposit range may cap the real-dollar benefit — read the maximum bonus amount, not just the headline percentage |
| Free Spins | 950,000 GC + SC 75 + 20 Free Spins on Gorilla Slot | Sweepstakes-style credits (GC/SC) work differently from cash bonuses — understand redemption rules before assuming any of it is withdrawable |
| Ducky Luck | 500% up to $2,500 + 150 Free Spins | Free spin batches this size are usually paid out over several days rather than all at once — confirm the schedule |
We also track Captain Jack, Slots and Casino, Zumba Cards, Casino Extreme and Dream Royale, each carrying its own welcome structure and terms. None of these figures are guarantees of what a player will win — every casino game carries a built-in house edge, and results vary.
Eligibility and Legal Basics We Apply to Every Listing
Online gambling regulation in the US is set state by state, not nationally, so availability and rules depend on where a player is physically located, not just where they live. Before recommending any site, we expect it to hold a recognised licence appropriate to how it operates, and we build our eligibility notes around a few consistent points:
- Players must meet the legal minimum gambling age, which is typically 21 though some states and gambling formats set different thresholds
- Access is generally tied to physical presence within a state where the activity is permitted — a VPN doesn't change your legal location
- Sweepstakes-model sites operate under a different legal framework than licensed real-money casinos, which affects both eligibility and how winnings can be redeemed
We don't gatekeep beyond flagging this — it's on the reader to confirm their own state's rules before signing up anywhere.
How Deposits, Withdrawals and Verification Actually Work
Banking is one of the areas readers ask us about most, so we look at it on every operator we cover:
- Deposits — commonly accepted methods include debit cards, ACH bank transfers, online banking, select cryptocurrencies, and digital wallets where an operator supports them
- Withdrawals — processing times vary by method and by operator; crypto and e-wallet withdrawals tend to move faster than card or bank transfers, which can take several business days
- Fees — some methods carry processing fees or minimum withdrawal thresholds, so check the cashier page before relying on a particular option
- Verification (KYC) — expect to submit ID and proof of address before your first withdrawal clears; this is standard practice at licensed operators and a sign the site takes compliance seriously, not a red flag
The Games Behind the Bonuses
The welcome offers on this page are mostly built around slots, since free spins packages target that category specifically. But every operator we list also runs a wider library — table games such as blackjack, roulette and baccarat variants, video poker, and in most cases a live-dealer section streamed from a studio. Many of these same operators also run a sportsbook or separate sports betting product alongside the casino, which is worth knowing if slots and table games aren't the only thing you're after.
Security and Fair-Play Basics We Look For
We check that a site runs on HTTPS encryption before we include it, and we look for evidence that slot and table game outcomes are generated by certified random number generators, ideally with independent testing behind them. Return to Player (RTP) figures, where published, describe a long-term statistical average across thousands of rounds — they say nothing about what happens on your next spin, and no RTP figure should be read as a prediction.
Playing Within Your Limits
Every offer we cover comes with real terms attached — wagering requirements, expiry windows, maximum cashout caps — and we read them before writing anything up. We'd rather flag a weak bonus than let a strong headline number do the talking. Beyond the offer terms, we encourage setting deposit and time limits before playing, never gambling with money you can't afford to lose or with borrowed funds, and stepping away if it stops being enjoyable. Most licensed operators offer self-exclusion tools and account limits directly in the cashier settings. Our Responsible Gambling page has more detail on where to find support if gambling starts to feel like a problem.
Where Our Revenue Comes From
Online Casinos earns commission when a reader clicks through to a listed casino and signs up. This is standard for comparison sites and it does not decide our rankings — an operator's position reflects our assessment of its licensing, bonus terms, banking and support, not what it pays us. We'll say so directly when an offer has a limitation, even for the highest-rated listing on the page.
