Terms and Conditions
These terms and conditions govern your use of thunderfactory.com and explain what this site is, what it isn't, and what you agree to by reading and acting on the information here. By using this site, you accept the terms below. If you don't agree with them, please don't use the site.
What this site is — and isn't
Best Offshore Sportsbooks is an independent research and comparison resource covering offshore sportsbooks that accept US bettors — operators licensed outside the United States, in jurisdictions such as Curaçao, Panama, or Costa Rica, rather than by any US state regulator. We publish reviews, rankings and guides, including our best offshore sportsbooks for US bettors rankings, to help readers compare odds, bonuses, banking options and payout reliability.
We are not a sportsbook, a gambling operator, a payment processor, or a legal or financial adviser. We don't accept bets, hold customer funds, or process wagers. We don't operate any of the brands featured on this site, and we have no control over how they run their business, honor their terms, or handle customer accounts.
Offshore betting sits in a legal grey area
This is the single most important thing to understand before using this site or any offshore sportsbook. The operators reviewed here are licensed offshore, not by a US state or federal regulator. No state gaming commission oversees their operations, no state fund segregation rules apply to customer deposits, and no state dispute-resolution process exists if a payout is delayed, reduced, or refused.
Whether it is lawful for you personally to use an offshore sportsbook depends on the laws of your specific state, which vary and can change. We do not provide legal advice, and nothing on this site should be read as a legal opinion on your situation. If you are unsure whether offshore betting is permitted where you live, consult a qualified attorney before depositing any funds.
Age and eligibility
This site, and every sportsbook referenced on it, is intended strictly for adults aged 21 or older (or the minimum legal betting age in your jurisdiction, if higher). We do not knowingly provide content to, or collect information from, anyone under that age. If you are underage, please leave this site now. Age and identity verification requirements are set by each individual operator, not by us.
No guarantees, no financial advice
Nothing on thunderfactory.com constitutes a guarantee of winnings, a promise of profit, or investment advice. Sports betting carries a genuine risk of losing money, and no ranking, review, or bonus comparison on this site changes that. We do not present betting as a source of income, and we do not publish "locks" or guaranteed picks. Editorial ratings reflect our own research into odds, market coverage, banking, and reported payout behavior — they are not a promise of how any operator will treat your account.
Any tax implications of betting winnings are your responsibility. We do not provide tax advice; consult a qualified tax professional about your own obligations.
Commercial disclosure
Best Offshore Sportsbooks may earn a commission when readers click through to an operator listed on this site and sign up. This is how independent research sites like ours are funded. Commission never determines our rankings or ratings — an operator cannot pay for a better position, and we disclose known drawbacks even for top-ranked sites. You can read more about how we assess operators on our rankings page.
Bonus terms are set by the operator, not by us
Welcome offers, reload bonuses and promotions displayed on this site — such as deposit-match percentages or free bet credits — are supplied by the operators themselves and can change without notice. Figures shown here, including rollover or wagering requirements, minimum odds, and time limits where stated, are accurate as of our last review but are always subject to the operator's own current terms. Always confirm the full terms and conditions directly with the sportsbook before depositing, since we do not control, honor, or guarantee any bonus offer.
Accuracy and updates
We research licensing status, odds formats, banking options, payout speed and other details in good faith, and this page was last fact-checked on Sep 3, 2026. Offshore operators change their terms, banking partners, and even licensing arrangements without warning, so details can go out of date between updates. We make reasonable efforts to keep content current but cannot guarantee that every figure, method, or condition listed reflects an operator's live terms at the moment you read this.
Payments, payouts and third-party risk
Any information here about deposit or withdrawal methods — including bank cards, wire transfers, vouchers, or cryptocurrencies such as Bitcoin, Ethereum, Litecoin, USDT or USDC — describes what operators publish or what we have researched. We do not process any transaction, and we are not a party to any deposit or withdrawal you make with a sportsbook. Crypto values are volatile, and payout figures, limits, or fees can change. You accept full responsibility for any funds you deposit, wager, or attempt to withdraw with a third-party operator.
Responsible gambling
Betting should be entertainment, not a way to solve money problems or relieve stress, and it should only ever involve money you can afford to lose. Offshore sportsbooks may offer weaker responsible gambling tools and self-exclusion options than regulated US operators, so it's worth checking what controls, if any, an operator provides before you sign up. If gambling stops being fun or starts to feel difficult to control, free and confidential help is available through the National Council on Problem Gambling at 1-800-GAMBLER. See our Responsible Gambling page for more resources.
Limitation of liability
To the fullest extent permitted by law, Best Offshore Sportsbooks and its owners, contributors and affiliates are not liable for any loss, damages, or dispute arising from your use of an offshore sportsbook, including delayed or refused payouts, account limitations, bonus disputes, or losses from wagering. Use of any third-party operator is entirely at your own risk and subject to that operator's own terms.
Changes to these terms
We may update these terms and conditions periodically to reflect changes in our content, the operators we cover, or legal considerations. Continued use of the site after changes are posted means you accept the revised terms. Check back occasionally if you want to stay current.
