How to Choose a Bookmaker: A Checklist That Holds Up

To choose a bookmaker, check six things before anything else: that it holds a licence you can verify and accepts customers from your country, that its odds margins are competitive on the sports you bet, that its markets and limits fit your stakes, that its payment methods and withdrawal rules suit you, that its betting rules are clear, and that it offers proper limit and self-exclusion tools. Welcome bonuses come last. This guide turns those checks into a checklist you can apply to any sportsbook in about twenty minutes.

What makes a good bookmaker?

A good bookmaker is one you can trust to pay you, that offers fair prices on what you actually bet, and that treats its rules consistently. Everything else (design, bonuses, live streaming) is a feature on top. Many bettors choose on the size of the welcome offer, which is the one factor that matters least over a year of betting. A bookmaker that pays out reliably and offers a 3% margin instead of 6% on your favourite market will be worth far more than any one-off bonus.

We use the same checks for every bookmaker on this site. The weights and the way we turn them into a rating are explained on our about page.

Check 1: is the bookmaker licensed, and does it accept your country?

A licence tells you which regulator supervises the bookmaker, which rules it must follow and where you can take a complaint. Start in the website footer: a licensed operator names its company, its licence number and its regulator. Then verify that licence on the regulator’s own register, not just by trusting a logo. Our licence check guide shows how to do this for the main regulators, including the Malta Gaming Authority (MGA), the Anjouan authority, the Curaçao Gaming Authority (CGA) and the Tobique Gaming Commission.

Next, read the bookmaker’s list of restricted or excluded countries in its terms. Every international sportsbook has one, and some are long. If your country is on it, close the tab: opening an account from a restricted country, or using a VPN to hide where you are, breaks the terms, and the bookmaker can void your bets and keep your balance. Reblz, for example, lists its excluded territories in section 2 of its terms and conditions, including the United States.

Two countries need a special word.

• United Kingdom: only bookmakers licensed by the Gambling Commission may offer betting to people in Great Britain. GAMSTOP, the free national self-exclusion scheme, covers those licensed operators. None of the bookmakers listed on this site holds a Gambling Commission licence, and none is aimed at UK residents.
• United States: sports betting is legal only in states that have authorised it, and only with sportsbooks licensed by that state. None of the bookmakers on this site accepts US players. Our US sports betting page explains the state-by-state picture.

Elsewhere, the law differs by country: some countries license their own bookmakers and block others, some run state monopolies, and some do not regulate online betting at all. It is your responsibility to check the rules where you live.

Which licences do international bookmakers hold, and what do they mean for you?

Licences differ in how strict the regulator is and, above all, in what happens when you have a dispute. The table summarises the licences you will meet most often at international sportsbooks. In every case, complain to the bookmaker first and keep copies of everything.

One more point: a licence from one country does not make a bookmaker lawful in another. Many countries require bookmakers to hold their own national licence to serve residents, and an EU licence such as Malta’s does not override that. The details of each register are in our licence check guide.

Check 2: how big is the bookmaker’s margin?

The margin is the share of each market the bookmaker keeps on average, built into the odds. It is the most important number after the licence, because you pay it on every bet. You can measure it in a minute: convert the prices of every outcome in a market to implied probabilities (1 ÷ decimal odds) and add them up. The amount above 100% is the overround.

Worked example: comparing two bookmakers on one match

Prices are illustrative. On €5,000 of betting over a season, the difference between a 7.1% and a 2.5% margin is around €230 in expected cost, on the same bets. Run this check on the markets you use most, because margins can be low on headline football and high on smaller leagues, props or racing. The full method, including how to strip the margin to find fair odds, is on the betting odds explained page.

What does the margin cost over a year?

The table shows the expected cost of betting at different average margins for three levels of annual turnover (the total of all stakes, not deposits). Your real results will swing around these figures, but over a large number of bets they converge on them.

Turnover grows faster than most people expect, because winnings are re-staked. A bettor who deposits €500 over a year can easily turn over €5,000 or more. That is why the difference between bookmakers on price is worth more than the difference between their bonuses.

Check 3: does it cover the sports and markets you bet on?

Almost every sportsbook covers major football, tennis and basketball. Differences show up in depth: lower leagues, Asian handicap lines with quarter goals, player props, esports titles, racing from your country, and the in-play menu. If you bet mostly on one sport, open that sport’s section on each bookmaker you are considering and count the markets on a typical match. Our sport guides explain what to look for in football and tennis.

Also check features you will use: cash out (full, partial, auto), bet builders, early payout promotions, acca insurance, live streaming or match trackers, and the ability to change odds format and time zone. Reblz’s sportsbook page, for instance, lists early payout offers on football, ice hockey, basketball and American football, and combo insurance on multiples.

Check 4: what are the limits, and will it restrict your account?

Every bookmaker sets maximum stakes and maximum winnings per bet, per day or per market, and they are often lower on niche events. The bet slip shows the maximum when you enter a large stake. If you bet in larger amounts, test this before depositing much.

Bookmakers can also restrict individual accounts, lowering the stakes they accept from a customer who wins consistently, takes early prices that later shorten, or only bets on promotions. Terms usually reserve this right in general language. It is not unique to any brand. If being limited would end your interest in a bookmaker, favour bookmakers with deep, liquid main markets, and spread your betting across two or three accounts.

Check 5: which payment methods does it offer, and what do they cost?

Look at the payments page for the methods available in your country and currency, the minimum and maximum deposit, any fees, and whether the same method can be used to withdraw. Common options at international bookmakers are bank cards, instant bank transfers, e-wallets such as Skrill, Neteller and MiFinity, prepaid vouchers, local methods such as Interac in Canada, and crypto at some sites. Two details often catch people out: some bonuses exclude deposits made with certain e-wallets, and many bookmakers require withdrawals to go back to the method you deposited with. Our payment methods guide compares the main options.

Currency matters too. If your account is in euros and your bank card in another currency, your bank’s conversion fee applies to every deposit and withdrawal. Prefer a bookmaker that offers your currency, or an account currency that matches your payment method.

Check 6: how fast are withdrawals, and are there caps?

Withdrawal terms tell you more about a bookmaker than its welcome offer. Look for three things in the terms: processing time (how long the bookmaker takes to approve a withdrawal, before your payment provider’s own time), minimum withdrawal, and maximum withdrawals per day, week or month. Some international sportsbooks cap withdrawals well below what a large win could be, then pay the rest in instalments.

Caps like these are not unusual, but they matter if you stake large amounts or chase big accumulators. A bookmaker that cannot pay a large win in one go is a poor home for high stakes.

Check 7: when will it ask you to verify your identity?

Licensed bookmakers must verify who you are under anti-money-laundering rules. In the European Union, Directive (EU) 2015/849 requires gambling operators to apply customer due diligence on transactions of €2,000 or more and whenever money laundering is suspected, national rules often go further, and in practice most bookmakers verify far earlier, often at the first withdrawal. Expect to upload photo ID, proof of address and sometimes proof of the payment method or source of funds.

Verification is not a red flag; delays and moving goalposts are. Read the terms to see when KYC is required and how long it takes. A good practice is to verify your account soon after registering, before you have a withdrawal waiting. Use your real details: an account opened in someone else’s name, or with false details, will be closed and its balance can be withheld.

Check 8: are the betting rules clear?

Each sportsbook publishes betting rules: how it settles void events, postponed matches, retirements in tennis, dead heats, overtime, abandoned matches and obvious price errors. These rules decide close calls, so skim them for your main sports before you bet. Look for specific wording, such as “a tennis match bet stands if one set is completed”, rather than vague promises. The bet types page explains the common settlement rules, and the live betting guide covers bet delays and late-bet rules.

Also check the rule on palpable errors (obviously wrong prices). Every bookmaker reserves the right to void or re-settle such bets. A fair rule defines what counts as an error and re-settles at the correct price instead of voiding winning bets after the event.

Check 9: is the bonus worth having?

A bonus can add value, but only after its rollover. Read four numbers: the rollover multiple and what it applies to (bonus only, or deposit plus bonus), the minimum odds, the time limit, and the maximum conversion. Then estimate the cost of clearing it at a realistic margin. Reblz’s sports welcome, for example, is 100% up to €400 with a 6x rollover on deposit plus bonus at minimum odds of 1.50 within 21 days. Our bonuses guide shows how to value it and when to decline.

Check 10: what safer-betting tools does it offer?

A responsible bookmaker lets you set deposit limits, loss or wager limits, session reminders, time-outs (a break of a day to several weeks) and self-exclusion (closing your account for months or years) from your account settings, without needing to argue with support. It should also link to independent help. Check that the tools exist before you deposit, because you may want them later. Our safer betting page lists the tools and where to find free, confidential help.

Check 11: how good is customer support?

Look for 24/7 live chat or at least clearly stated hours, an email address, and a help centre that answers real questions (withdrawals, verification, bet settlement). Test it with one question before you deposit: how quickly and clearly the bookmaker answers is a good sign of how it will handle a problem later. Check also whether support is available in your language.

Check 12: does the site work well on your phone?

Most bets are now placed on phones, so test the mobile site or app: speed, how easy it is to find markets, how the bet slip behaves in-play, and whether cash out works. Real-money betting apps in the major app stores must follow the store’s rules for licensed gambling apps (Apple’s App Store guideline 5.3.4, for example, requires licensing and geo-restriction), so many international sportsbooks offer a mobile website rather than a store app. A well-built mobile site is fine; be wary of downloading betting apps from unofficial sources.

Security belongs in the same check. Look for two-factor authentication on login, a clear way to see your active sessions, and email or text alerts on withdrawals. Use a unique password for every bookmaker and never share account access: most terms make you responsible for every bet placed on your account, and shared or sold accounts are a common reason for balances to be withheld. If a bookmaker offers withdrawal locks or a cooling-off period on changes to your payment details, switch them on.

How do you compare bookmakers in twenty minutes?

You do not need weeks of testing to rule a bookmaker in or out. A short, structured check catches most problems. Here is the routine we use, applied to an example where you bet mainly on football and tennis with stakes of €10 to €50.

1. Two minutes, footer and terms: note the company, licence number and regulator; open the restricted-countries clause and confirm your country is not on it.
2. Three minutes, register: look the licence up on the regulator’s register or seal validator. If it does not match the footer, stop.
3. Five minutes, prices: pick two upcoming football matches and one tennis match. Add up the implied probabilities on the match-result and Asian handicap markets. Compare with a second bookmaker.
4. Three minutes, payments: open the payments page; note methods for your country, minimums, fees and withdrawal caps.
5. Three minutes, rules: search the betting rules for “retire”, “abandon”, “void” and “palpable”.
6. Two minutes, tools: check the responsible gambling page for deposit limits, time-outs and self-exclusion.
7. Two minutes, support: ask live chat one practical question, such as how long the first withdrawal takes.

Score each check from 0 to 2 (fail, acceptable, good), with the licence as a pass-or-fail gate. A bookmaker that scores well on margin, withdrawals and tools is worth an account; one that fails any of the gate checks is not, however good its bonus looks.

What should you search for in the terms?

Terms and conditions are long, but a handful of searches find the clauses that matter. Use your browser’s find function on the general terms, the sports betting rules and the bonus terms.

Dormant-account fees are worth a special look: Foxy Gold’s terms, for example, charge an inactive account fee after a period of inactivity, which can slowly empty a balance you forgot about. If you stop using a bookmaker, withdraw your balance and close the account.

Are new bookmakers worth trying?

New sportsbooks launch every month, often with large welcome offers to win customers. Some are solid; many are new brands on an existing platform, run by a company that operates several near-identical sites. Neither is a problem in itself, but a new brand has no track record of paying large withdrawals or handling complaints. Apply the same checks with extra care: verify the licence, read the withdrawal caps, and start with a small deposit and a test withdrawal. Our bookmaker reviews note when a brand first appeared where we could date it.

Do language, currency and odds format matter?

They matter more than they look. Support in your language makes disputes easier to resolve. An account in your own currency avoids conversion fees on every deposit and withdrawal; a bookmaker that offers only euros will cost you a bank conversion fee each time if your card is in another currency. Odds format is a preference: most international sportsbooks let you switch between decimal, fractional and American odds in the settings, and some also offer Asian formats. Time zone settings help too, especially for live betting on events in other continents. None of these should outweigh licence, margin or withdrawals, but they decide how pleasant a bookmaker is to use every day.

Why we do not rank bookmakers by popularity

Lists of “popular” or “recommended” bookmakers are often ranked by how much each bookmaker pays the publisher, or simply by brand size. Popularity tells you little about whether a bookmaker suits you: the biggest brands may not accept your country, and a small one may offer better prices on your sport. We list only bookmakers whose licence, eligibility rules and sports offer we could verify on their own pages, and we say which facts we could not confirm. We may be paid when readers join some of the bookmakers we list; that never changes the facts we report, and how we work is set out on our about page.

How do you register and make a first deposit?

1. Check eligibility first: confirm your country is not on the restricted list and you are of legal age where you live (18 or older at minimum).
2. Register with real details: name, date of birth, address, email and phone number exactly as on your ID. Choose a strong, unique password.
3. Set limits straight away: add a deposit limit in your account settings before you deposit. Many bookmakers apply decreases instantly and increases only after a waiting period.
4. Read the bonus terms before depositing: some sports welcome offers need a code or a choice in the cashier at the moment of the first deposit, and some exclude certain payment methods.
5. Make a small first deposit: use a method you can also withdraw to, in your own name.
6. Verify early: upload ID and proof of address before you need to withdraw.
7. Test a small withdrawal: it shows you the real processing time and any fees before larger amounts are involved.

What red flags should make you walk away?

• No company name or licence number in the footer, or a licence you cannot find on the regulator’s register.
• Terms that cannot be found, contradict each other or change without notice.
• Welcome offers far out of line with the rest of the market, with rollover rules you cannot locate.
• Pressure to deposit more, unsolicited messages offering “guaranteed” or “fixed” bets.
• Withdrawal caps or fees buried deep in the terms, or a history of complaints about unpaid withdrawals.
• No way to set limits or self-exclude from your account.
• Support that cannot say which regulator or dispute body covers your account, or that answers questions about withdrawals with bonus offers instead.
• A domain that changes often (mirror sites) with no explanation, which makes it harder to know which terms apply to you.

How do the bookmakers we list compare on these checks?

The table summarises facts from each operator’s own pages, checked between 7 and 15 October 2026 (Stake on 7 October). Full profiles are on our bookmaker reviews page.

None of these is licensed in an EU member state’s own national system apart from Reblz’s Malta licence, and none holds a Gambling Commission or US state licence. An MGA licence is generally the strongest of the licences listed here because of the regulator’s rules and the ADR requirement, but it does not make a bookmaker lawful in countries that require a local licence.

What can you do if a bookmaker will not pay?

Disputes usually start with a delayed withdrawal, a voided bet or a closed account. Work through them in order and keep a written record at every step.

1. Ask in writing: use email or the support ticket system, not only live chat, and ask the bookmaker to cite the exact term it relies on.
2. Ask for a final response: most licensed operators have a complaints procedure with a deadline for answering. Anjouan-licensed operators, for example, have 30 days to respond under the authority’s complaint policy.
3. Go to the ADR body: if the licence requires an alternative dispute resolution service, the bookmaker must tell you which one. For MGA licensees this is an approved ADR body; for Curaçao licensees it is one of the CGA-certified ADR bodies.
4. Inform the regulator: even where the regulator does not settle individual disputes, it can act on patterns of complaints against a licensee.
5. Payment route: for card deposits, your card issuer’s dispute process may apply within its time limits; this does not usually cover winnings, only deposits in specific circumstances.

Before any of this, read the terms the bookmaker cites. Many disputes come from rules the customer did not know about, such as a bonus rule that voided winnings or a restricted-country clause, and knowing that early saves time. If the licence cannot be verified at all, your options are very limited, which is the strongest reason to check it before you deposit.

Bookmaker or betting exchange?

A betting exchange matches bets between customers and charges a commission on net winnings, instead of setting prices with a built-in margin. Exchange prices on big football, tennis and racing markets are often close to fair, and you can also lay (bet against) an outcome. The trade-offs are liquidity (small markets may have little money to match), commission, and the fact that exchanges are licensed in fewer countries than bookmakers. Many bettors keep both: a bookmaker for promotions, bet builders and niche markets, and an exchange where it is available and legal for them, to compare prices. The bet types page explains how a lay bet works.

How do you leave a bookmaker properly?

If you stop using a bookmaker, withdraw the balance first, then close the account through the settings or by asking support in writing. Ask for confirmation that marketing messages will stop. If you are leaving because betting has become a problem, use self-exclusion rather than a simple closure: self-exclusion is designed to block you from reopening the account for a set period, while a closed account can often be reopened by asking. The safer betting page explains the difference and where to get free help.

Should you have more than one bookmaker account?

Usually yes. Two or three accounts let you take the best price on each bet, which over a season is worth more than any bonus. They also protect you if one account is limited, or if one bookmaker suspends a market you want. The trade-off is discipline: more accounts make it harder to track spending, so keep one record of all bets and a combined monthly budget, and set deposit limits on every account.

Frequently asked questions

What is the most important thing when choosing a bookmaker?

A licence you can verify on the regulator’s own register, for a bookmaker that accepts customers from your country. Without that, nothing else matters, because you have no reliable route to complain if the bookmaker does not pay.

How can I tell if a bookmaker is legit?

Check the footer for the operating company, licence number and regulator, then look the licence up on the regulator’s register. Read the terms for restricted countries and withdrawal rules, and test support with a question before you deposit.

Which bookmaker has the best odds?

It depends on the sport and market. Measure the margin yourself by adding up the implied probabilities of all outcomes in a market at each bookmaker. The lower the total above 100%, the better the prices on that market.

Why do bookmakers ask for ID?

Anti-money-laundering law requires licensed operators to verify their customers’ identity, and EU rules require checks on gambling transactions of €2,000 or more (and whenever money laundering is suspected). Most bookmakers verify earlier, typically before the first withdrawal.

Can a bookmaker limit my account?

Yes. Bookmakers reserve the right to set lower maximum stakes for individual customers, often those who win regularly or bet mainly on promotions. Spreading your betting across a few accounts with deep main markets reduces the impact.

Is a big welcome bonus a good reason to choose a bookmaker?

Rarely. A bonus is a one-off and its value depends on the rollover terms, while the margin, limits and withdrawal rules affect every bet you place afterwards. Treat the bonus as a tie-breaker between bookmakers that pass the other checks.

How many bookmaker accounts should I have?

Two or three is a practical number for most bettors. It lets you compare prices on every bet and keeps you betting if one account is limited, without making it hard to track your spending. Set a deposit limit on each account and keep one combined record.

What should I do before my first withdrawal?

Verify your account by uploading ID and proof of address, check the minimum withdrawal and any daily or monthly caps in the terms, and make sure you withdraw to a method in your own name, usually the one you deposited with. A small test withdrawal shows the real processing time.
