About Us
International Betting Sites is an independent research site for US bettors who are looking at offshore sportsbooks — betting sites licensed outside the United States that accept American players in states without a regulated online market. We compare these operators on the things that actually decide whether a sign-up is worth it: bonus value and terms, odds, market coverage, banking options, payout speed, and track record. We don't accept bets ourselves, and we're not a sportsbook. We're a research and comparison resource.
Why This Page Leads With Bonus Value
Most readers land here already knowing what an offshore sportsbook is — the question is which one gives the most usable value for a first deposit. That's why our rankings put welcome bonus size and terms front and center, but we never score a bonus on its headline number alone. A "125% up to $1,250" offer and a "50% up to $250" offer aren't directly comparable until you factor in the rollover requirement, the minimum odds needed for bonus bets to count, the time limit to clear it, and which sports or bet types are excluded. We read the fine print on every offer before it goes into a ranking.
What We Actually Cover
Every review and comparison on this site is built around five things a reader needs before signing up anywhere:
- Legal standing. Every offshore sportsbook we cover is licensed outside the US — typically in jurisdictions like Curaçao, Panama, or Costa Rica — and none of them are regulated by any US state. That means no state-backed player protections, no segregated-funds guarantee, and no access to a state gaming commission if a dispute arises. This is a legal grey area for US bettors, and it's on the reader to check the law in their own state before depositing anywhere.
- The money side. How much a bonus is really worth once rollover and minimum-odds conditions are applied, plus how deposits and withdrawals work — card, wire, voucher, or crypto — and what fees or delays to expect.
- What's on offer. Point spreads, moneylines, totals, parlays and same-game parlays, props, futures, and live in-play betting, along with the sports and leagues each operator actually covers well versus thinly.
- The wider product. Most of these operators run casino games, poker, or racebook products alongside sports betting, and we note where that's relevant so readers aren't surprised by what's on the platform.
- Reliability. Payout speed, withdrawal limits, verification (KYC) requirements, site security, and how each book has handled customer payouts historically, based on publicly available reputation data and our own research.
Our Review Method
We score each sportsbook against a consistent set of criteria rather than a gut feeling:
| Factor | What we check |
|---|---|
| Bonus value | Headline offer weighed against rollover, minimum odds, time limits and eligible markets |
| Odds and pricing | Vig/juice levels and how they compare across similar markets |
| Market coverage | Depth of sports, leagues, prop markets, and in-play options |
| Banking | Deposit and withdrawal methods, crypto support, processing times, fees and limits |
| Track record | Years operating, verification requirements, and reputation for paying out |
Ratings are editorial judgments based on this research, not customer-submitted review scores, and no operator can pay to move up the rankings. Commission from affiliate partnerships never decides where a sportsbook lands on this page or in our comparisons.
How the Rankings on This Site Are Built
Right now, Lucky Rebel tops our list, currently offering a 125% match up to $1,250 plus a 50 free bet — a strong headline figure, but as with every bonus here, it comes with rollover requirements that need clearing before any bonus funds can be withdrawn, so it suits bettors who plan to be active rather than make a single small bet. Bovada, long established with US bettors, offers a more modest 50% up to $250 welcome bonus, trading bonus size for a longer operating history. BetOnline rounds out our top three with a $250 free bets offer and broad market coverage across US and international sports. Further down the list, operators like BetNow, Everygame, BetUS, Sportsbetting, Xbet, MyBookie, and ApuestaHoy each bring their own mix of bonus structure, market depth, and banking options — all detailed in our individual reviews and comparisons.
None of these bonuses should be read as free money in hand. Every offer requires a real deposit or wager to unlock, comes with a rollover requirement that must be met before withdrawal, and is subject to minimum-odds rules and expiry windows. We list the headline figure next to those conditions wherever we cover a specific offer, rather than in a disclaimer buried elsewhere.
The Risk We Won't Downplay
Offshore sportsbooks operate outside US regulatory oversight. That has upsides for bettors — often better odds, higher limits, broader markets, and crypto payout options — but it also means no state-backed dispute process if a withdrawal is delayed or refused, and no guarantee that funds are held separately from the operator's own money. Crypto payments carry their own risk too: currency values can move between the time you deposit and the time you're paid, and that volatility isn't something we or any sportsbook controls. We factor payout reputation into every rating, but we can't promise any offshore operator will pay every time. Betting always carries the risk of losing your stake, and no bonus, odds boost, or bet changes that.
Age, Eligibility, and Responsible Gambling
Every sportsbook covered on this site requires players to be at least 21 years old (18 in some cases, depending on the operator's own terms), and this site is not intended for anyone under that age. We do not target or write for underage readers.
Betting should never be treated as a way to make money reliably, escape financial pressure, or chase back losses — the house edge means the odds favor the book over time, not the bettor. If gambling stops being entertainment and starts feeling like a problem, free confidential help is available through the National Council on Problem Gambling at 1-800-GAMBLER. Offshore sportsbooks may offer weaker self-exclusion and responsible gambling tools than regulated US operators, so it's worth setting your own limits before you deposit. Our Responsible Gambling page has more on the tools and support available.
Tax and Legal Notes
Winnings from offshore sportsbooks may still be subject to US federal and state tax reporting obligations, and the legal status of betting with an offshore operator varies by state. Nothing on this site is tax or legal advice — for guidance specific to your situation, speak with a qualified tax professional or attorney. Full terms for using this site are set out in our Terms and Conditions.
