About Us

Best Offshore Sportsbooks was built for one purpose: to help US bettors make sense of offshore sportsbook welcome offers and reload promotions before they hand over any money. Offshore betting sites operate outside US state regulation, and their bonus terms vary enormously from one book to the next. This page explains who we are, how we research these offers, and what we do — and don't — claim on this site.

Why We Focus on Bonuses

Welcome bonuses and reload offers are usually the first thing a bettor compares when choosing between offshore sportsbooks, and they're also the part most likely to be misunderstood. A headline number like "125% up to $1,250" or "$250 in free bets" means very little without the rollover requirement, minimum odds, eligible markets and time limit attached to it. Our reviews exist to put those conditions next to the offer itself, not buried in a separate terms page, so readers can compare what a bonus is actually worth to them before they deposit.

How We Put This List Together

We research each offshore sportsbook's bonus terms directly from the operator's own published rules, then cross-check the wagering requirements, minimum odds, maximum bonus amounts and eligibility restrictions that apply. We also look at how the bonus fits alongside the book's broader offering — odds quality, sports and market coverage, payout speed, banking options including crypto, and customer support — since a generous-looking bonus is worth less at a site that's slow to pay or hard to reach.

Our editorial ratings reflect this combined research. No operator pays for a better position on this site, and commercial relationships — including any affiliate arrangements we have with the books we list — never decide the ranking order. Where we earn a commission from a reader signing up through one of our links, that has no bearing on where a book sits in our comparisons.

What "Offshore" Actually Means Here

Every sportsbook covered on cambiodesign.org is licensed outside the United States, typically in jurisdictions such as Curaçao, Panama or Costa Rica, and none of them are licensed or regulated by any US state gaming authority. That distinction matters. Betting with an offshore book sits in a legal grey area for US bettors — it isn't the same as using a state-licensed operator, and none of the consumer protections that come with US regulation, such as segregated player funds or a state-backed dispute process, apply. If an offshore book delays or disputes a payout, a US bettor has far less recourse than they would with a regulated operator. We flag this on every review, and we'd rather a reader skip a site than sign up without understanding that risk.

Laws and enforcement postures around offshore betting differ by state and can change. We give general information only — nothing on this site is legal or tax advice, and readers should check their own state's current laws and speak with a qualified professional about their specific situation before betting with an offshore book.

What Our Reviews Cover

A typical review on this site works through the same core questions for every book we list:

• Where the sportsbook is licensed and what that licence does — and doesn't — guarantee
• The welcome bonus and any reload offers, including rollover requirements, minimum odds and time limits
• Odds quality and pricing across spreads, moneylines, totals, props, parlays and futures
• Sports and market coverage, including live and in-play betting
• Deposit and withdrawal methods, including cryptocurrency, bank cards and wire transfer, along with typical fees and limits
• Payout speed and the book's track record for actually paying out
• Verification and KYC requirements at sign-up and at withdrawal
• Customer support quality and mobile or app usability

We name and rank only the operators listed in our current comparisons — Lucky Rebel, Bovada, BetOnline, BetNow, Everygame, BetUS, Sportsbetting, Xbet, MyBookie and ApuestaHoy — based on the research above, and we update figures and terms as we reconfirm them.

What We Won't Tell You

We won't tell you that a bonus is free money, that any bet is a guaranteed winner, or that betting can be a reliable way to make income. It can't be, and no honest sportsbook comparison should suggest otherwise. Every wager carries a real risk of loss, and with an offshore book there's an added risk that a withdrawal could be delayed or disputed, since these operators sit outside US regulatory oversight. If you're weighing up crypto payouts, remember that the value of Bitcoin, Ethereum, Litecoin and other coins can shift between the time you fund an account and the time you cash out, which is a risk on top of the bet itself.

Betting Responsibly

Nothing on this site is aimed at anyone under 21. Sports betting should be entertainment, not a way to cover bills, relieve stress or chase back losses, and offshore sportsbooks often provide fewer responsible gambling and self-exclusion tools than regulated US operators. If betting stops feeling like entertainment, free and confidential help is available around the clock through the National Council on Problem Gambling helpline at 1-800-GAMBLER. Our responsible gambling page has more on the tools and support available.
