About Us

Casino Sites exists to help American players tell the difference between an online casino worth signing up to and one that just looks the part. We research licensed operators serving US players, compare their bonuses, banking options and game libraries side by side, and publish what we find — including the parts that aren't flattering.

We don't operate a casino ourselves and we never accept deposits or handle player funds. Our job is narrower and, we think, more useful: reading the fine print so you don't have to, then laying out the results plainly.

Why We Built This Site

Online gambling regulation in the US is a patchwork rather than a single national system — legality, licensing and available operators vary from state to state. That makes it easy for players to land on a site that isn't actually permitted to serve them, or to miss bonus terms that turn a "welcome bonus" into a withdrawal headache. Our starting point on every page is the same: only cover casinos that operate under recognized licensing, confirm the site uses HTTPS encryption, and read the bonus terms in full before we describe an offer as good value.

What We Actually Check

Every operator on this site is assessed against the same set of questions, not a rotating standard designed to make one site look better than another.

• Licensing and oversight — who regulates the operator, and whether that licence gives players a route to complain or seek redress if something goes wrong
• Bonus terms — the wagering requirements, expiry dates, maximum withdrawal caps, and which games count toward clearing a bonus
• Banking options — deposit and withdrawal methods available to US players, along with processing times and any fees
• Game fairness — whether slots and other applicable games run on certified random number generators, and whether independent testing labs are named
• Return to Player (RTP) — published RTP figures where available, and what that number does and doesn't tell you about a single session
• Identity verification — what documentation a player is likely to need before a withdrawal clears
• Customer support — the channels on offer and how easy it is to reach a real person when something needs sorting

Ratings shown against operators such as Raging Bull, Uptown Aces and Ignition reflect this same checklist applied consistently. A higher-ranked site on this page has scored better across these criteria — it doesn't mean every reader will find it the best fit, which is why we still note a genuine limitation alongside every recommendation rather than presenting any operator as flawless.

How the Money Side Works

US players typically fund casino accounts through a mix of ACH bank transfers, debit cards, online banking, digital wallets, and increasingly cryptocurrency; some sites also support cash deposits at partner locations. Withdrawal methods usually mirror deposit options, though processing times differ by method and by operator — bank transfers and cash options tend to be slower than e-wallets or crypto. Fees, where they exist, are usually tied to a specific method or to withdrawal frequency rather than applied across the board. We flag these details in individual reviews rather than assuming one payment experience applies everywhere.

Eligibility and Legal Standing

Real-money online casino play in the US generally requires a player to be at least 21 years old, though some gambling activities carry different age thresholds depending on the state. Availability is also tied to where a player is physically located when they play, not just where they live — most licensed real-money platforms use geolocation checks to confirm a player is within a state where online casino gaming is permitted. We write general guidance based on how this typically works; we don't claim to hold or verify any operator's specific licence ourselves, and we always recommend confirming a site's current legal status in your state before creating an account.

Bonuses: What the Headline Number Doesn't Tell You

A welcome offer like the ones listed on this site — percentage match bonuses, free spins, or deposit credits — always comes attached to conditions that affect what a player can actually withdraw. Typical terms include:

• Wagering requirements — how many times the bonus (or bonus plus deposit) must be played through before withdrawal
• Game restrictions — some titles contribute fully to wagering, others partially or not at all
• Expiry windows — bonuses that go unclaimed or unused within a set period are typically forfeited
• Maximum withdrawal caps — some bonuses limit how much bonus-derived winnings can actually be cashed out

We treat the headline match percentage as one data point, not the whole story, and encourage every reader to check an operator's own terms page before opting in.

Responsible Gambling Comes First

Every game of chance carries a built-in house edge, and no strategy changes that over the long run. RTP figures describe a statistical average across millions of rounds — they say nothing about what happens in any single session, win or lose. We'd rather be upfront about that than let a bonus headline do the talking.

Practical steps we recommend to every reader, regardless of which operator they choose:

• Set deposit and time limits before you start playing, not after
• Never gamble with money you can't afford to lose, and never with borrowed funds
• Use self-exclusion tools if play stops feeling like entertainment
• Reach out to state or national support services if gambling starts affecting your finances or wellbeing

Our Responsible Gambling page has more detail on limit-setting tools, self-exclusion programs, and where to find support.

Security and Fair Play

We check that the operators we cover use HTTPS encryption to protect account and payment data, and we look for evidence of independent testing on their random number generators where that information is published. We'd encourage every player to do the same before signing up anywhere — a padlock in the browser bar and a visible licence number are quick, practical checks anyone can make in under a minute.

Where Our Revenue Comes From

Casino Sites earns commission when a reader clicks through to an operator and signs up. This funds the site, but it doesn't buy placement — no casino pays for a higher rating, and our rankings reflect the same criteria applied across every operator we cover. If a site falls short on licensing clarity, bonus fairness, or payment speed, we say so, commercial relationship or not.

If something on this site looks out of date, or you've spotted an operator detail that's changed, the Contact Us page is the quickest way to reach us. Readers outside the US looking at offshore options should also see our coverage of Non Gamstop casinos, which covers a different regulatory picture entirely.
