About Us

Best Offshore Sportsbooks was built around one question a lot of US bettors are quietly asking: which offshore sportsbooks actually work well on a phone, and which ones just say they do. We spend our time researching mobile apps and mobile browser sites so that readers comparing options don't have to open ten tabs and ten sign-up forms to find out for themselves.

What we actually do

integrationconference.org is an independent research and comparison site. We look at offshore sportsbooks — operators licensed outside the United States that accept US bettors — and compare them on the things that matter most for mobile users: how the app or mobile site handles live betting, how quickly odds update on a small screen, how deposits and crypto withdrawals work from a phone, and how each book's welcome offer reads once you get past the headline number. We are not a sportsbook, we don't take bets, and we don't process payments.

What we don't do

We don't claim these sites are licensed or regulated in the US, because they aren't. Offshore sportsbooks operate under licenses from jurisdictions such as Curaçao, Panama, or Costa Rica, not under any US state gaming authority. That distinction matters: it means the consumer protections a regulated US sportsbook must offer — segregated player funds, a state dispute-resolution process, guaranteed payout timelines — do not apply here. Betting with an offshore book sits in a legal grey area for US players, and the laws vary by state. We'd rather say that plainly than let a reader assume otherwise.

How we assess mobile offshore sportsbooks

Our rankings weigh several factors, and no operator pays for a better position — commission from a sign-up never decides where a book sits on our list. We look at:

• Mobile app and browser performance — load speed, navigation, live/in-play betting responsiveness, and whether the full desktop market list carries over to mobile
• Odds and market coverage — pricing on spreads, moneylines, totals, props, futures, and same-game parlays, and how much of that is available in-app versus desktop-only
• Bonus terms — the headline offer plus the rollover requirements, minimum odds, and time limits that actually determine whether it's worth claiming
• Banking on mobile — deposit methods including cards and cryptocurrency (Bitcoin, Ethereum, Litecoin, and stablecoins like USDT and USDC), plus reported withdrawal speed and any fees
• Track record — how long an operator has been taking US players and what its public reputation for paying out looks like

We base this on publicly available information, operator terms, and our own review of each site's mobile interface. We have not deposited, wagered, or withdrawn funds as part of this process, and we describe our work as research and review, not testing in the sense of placing real bets.

Why offshore books, and why the risk still stands

Readers come to offshore sportsbooks for reasons that make sense: their state hasn't legalized regulated online betting, or they want higher limits, broader markets, or reduced-vig pricing that regulated books don't offer. That's a legitimate reason to look at this market — but it doesn't remove the risk. An offshore operator can, in principle, delay or refuse a payout with far less recourse for the customer than a regulated US book would allow. If you fund an account with cryptocurrency, you also carry the added risk of price volatility between deposit and withdrawal. None of this is guaranteed to happen, but none of it is impossible either, and we'd rather flag it here than bury it in a footnote.

Age, eligibility, and responsible gambling

Everything on this site is intended for readers 21 and older. We do not create content aimed at, or appealing to, anyone under that age. Betting should never be treated as a source of income, and no offer or bonus on this site is a guarantee of winning anything — every bet carries a real chance of losing money. If gambling stops feeling like entertainment, free tools and support are available, and we'd encourage anyone concerned about their own play, or someone else's, to visit our responsible gambling page or call 1-800-GAMBLER. Offshore sportsbooks often provide lighter self-exclusion and account-limit tools than regulated US operators, so it's worth checking what's actually available before you sign up.

Questions, corrections, or feedback

If you spot something on this site that looks out of date — a bonus figure, a licensing detail, anything — we want to know. You can reach us through our contact page, and our full terms of use are laid out on our terms and conditions page. We update our comparisons periodically, but sportsbook terms change often, so always check the operator's own site before you rely on a figure we've quoted.

Before you use this site

Nothing here is legal or tax advice. Whether offshore betting is permissible where you live is a question of your own state's law, and we'd recommend checking that — and speaking to a qualified professional about any tax obligations from your winnings — before you deposit anywhere. Our job is to compare what's on offer and be honest about the trade-offs; the decision, and the risk, is yours to weigh.
