About Us
Best Online Casinos was built for one reason: to help players in the US cut through the noise of endless welcome offers and work out which online casinos are actually worth their time. We look at licensed, regulated operators, compare what they offer new players, and lay out the terms plainly so you can decide before you deposit a single dollar.
Why we lead with the biggest bonus
Search for the best online casinos and the first thing most people want to know is: which site gives me the most for my money at sign-up? That's the lens we use across visitmacysusa.com. A welcome bonus is often the single biggest factor separating one casino site from another for a new player, so our rankings put bonus size and structure front and center — while still checking that the offer is realistic to use, not just impressive on paper.
A large headline percentage means little if the wagering requirement is unreasonable or the game restrictions rule out the titles you actually want to play. So every casino on our list is judged on the full package: the deposit match, the spins or bonus credit attached, and the conditions that come with them.
How we assess the operators we cover
Our rankings are compiled through independent research, not paid placement. Commission from an operator, where it exists, never buys a better position on this site — a casino ranks where it does based on the same set of criteria applied to every entry:
- Size and realism of the welcome bonus, including wagering requirements and expiry windows
- Licensing and regulatory standing relevant to US players
- Range of games — slots, table games and live-dealer options
- Banking methods available for deposits and withdrawals, and typical processing times
- Site security, including use of encryption on deposit and account pages
- Customer support channels and responsiveness
We update our findings as offers, terms and licensing details change, and we note the date this page was last reviewed at the top of the article.
What "biggest bonus" actually means in practice
Bonuses on this page range from deposit matches like Raging Bull's 410% up to $10,000 plus 50 free spins and Uptown Aces' 600% offer for new players, through to sweepstakes-style credits such as the Free Spins site's 950,000 GC plus SC 75 and 20 free spins on a featured slot. These structures aren't interchangeable — a percentage match works differently from a sweeps coin package, and a crypto-friendly bonus like Bets.FM's 225% up to 1 BTC comes with its own funding requirements. We explain these differences rather than assuming one number tells the whole story.
Every bonus carries conditions: a wagering multiple, a maximum bet while the bonus is active, an expiry date, and often a cap on how much can be withdrawn from bonus winnings. We read those terms before an offer appears on this site, and we recommend readers do the same before claiming anything.
What we check before naming a casino
Beyond the bonus itself, we look at the practical things that affect a real player's experience:
| Area | What we look for |
|---|---|
| Licensing | Valid licensing appropriate to the markets the casino serves, since this underpins oversight and dispute resolution |
| Payments | Range of deposit and withdrawal options, including ACH transfers, debit cards, digital wallets, online banking and crypto where supported |
| Game fairness | Use of certified random number generators for slots and other applicable games, and independent testing where it's disclosed |
| Security | HTTPS encryption on the site and clear account verification (KYC) processes before withdrawals |
| Support | Availability of live chat, email or phone support, and how quickly queries tend to get answered |
What we don't do
We don't test casinos by depositing or playing ourselves, and we don't claim any operator is guaranteed to pay out or that a bonus guarantees a win. Return to Player (RTP) figures quoted by casinos are long-term statistical averages, not a promise about any individual session, and every game of chance carries a built-in house edge. Our job is to lay out what's on offer and what it costs to use, not to predict outcomes.
Eligibility and responsible play
Online gambling is regulated at the state level in the US, and legal availability depends on where a player is physically located, not just where they live. Players generally need to be of the legal gambling age for their state — commonly 21 — and located within a state where online casino play is permitted. We don't cover eligibility rules for every state on this page, but we flag it clearly because it affects whether a bonus is even something you can claim.
We also take responsible gambling seriously. Set a deposit and time limit before you play, never chase losses with borrowed money, and stop if gambling stops being enjoyable. Most licensed casinos offer self-exclusion tools and links to state or national support services; our Responsible Gambling page has more detail on where to find help if you or someone you know needs it.
Questions, corrections or feedback
If you spot an outdated bonus, a licensing detail that's changed, or you simply want to ask us something about how a casino works, you can reach the team through our Contact Us page. We also keep a full breakdown of the rules that govern this site, including how we handle content and liability, on our Terms and Conditions page.
Best Online Casinos exists to make comparing casino sites easier, not to push any single operator. Read the terms behind any offer that catches your eye, and treat every bonus as entertainment value first, not income.
