Before you deposit at an online casino, check five things: a licence you can verify on the regulator’s own register, bonus terms you can actually meet, a loyalty scheme that rewards rather than pressures you, customer support that answers, and a game lobby with published RTPs from known studios. Add a sixth for safety: clear withdrawal terms and easy-to-use limit tools. New casinos launch every month, and the differences between them are mostly in the small print, so this checklist takes about ten minutes and can save you a lost deposit or a blocked withdrawal.
Online casinos are for adults only: 18+ (higher in some countries). Our rating method uses the same checks, weighting licence, terms and payments before bonuses.
1. The availability of a proper licence
A licence means a regulator can inspect the operator, demand player protections and, in principle, take action when something goes wrong. Its value depends on who issued it and what that regulator does. Never rely on a logo in the footer. Click it or copy the licence number, then search the regulator’s own register and check that the company name and the website match.
| Regulator | Where to check | Complaint route for players |
|---|---|---|
| UK Gambling Commission | UKGC public register | Casino first, then the approved ADR body named by the casino |
| Malta Gaming Authority (MGA) | MGA licensee register or the site’s dynamic seal | Casino first, then an ADR provider such as eCOGRA; the MGA’s Player Support Unit stopped ruling on individual disputes on 1 April 2019 |
| Curaçao Gaming Authority (CGA) | CGA register (cga.cw) | Casino first, then one of the CGA-certified ADR bodies; the CGA does not mediate individual disputes |
| Anjouan | The site’s seal, validated by its seal ID | Through the seal: the operator has 30 days to respond, then an operator-paid ADR |
| Kahnawake Gaming Commission | KGC permit-holder list | Casino first, then the commission’s complaint procedure |
Two points are worth knowing. Curaçao’s new gaming law (Landsverordening op de kansspelen, LOK) came into force on 24 December 2024, and licences are now issued by the Curaçao Gaming Authority, so an old “Curaçao eGaming” sub-licence logo is no longer the right thing to look for. And a licence from one country does not make a casino legal everywhere: in Great Britain only UKGC licensees may serve British residents, and many European countries run their own licensing systems. Our guides to safe casinos and legal casinos explain the rules by country.
2. Great welcome bonuses, read properly
The headline number on a bonus is the least important part. Four terms decide its value:
- Wagering requirement: how many times you must stake the bonus (or deposit plus bonus) before withdrawing.
- Maximum bet: the largest stake allowed while the bonus is active, often EUR 5.
- Time limit: some bonuses must be cleared in 48 hours, others in 30 days.
- Game contribution: slots usually count 100%, table and live games little or nothing.
Here is why, in numbers. Take a 100% bonus up to EUR 200 with 40x wagering on deposit plus bonus. Deposit EUR 200, receive EUR 200, and you must wager EUR 16,000. On slots with a 4% house edge, the expected cost of that wagering is EUR 640, more than three times the bonus. A EUR 50 bonus with 10x wagering on the bonus only (EUR 500 to wager) costs about EUR 20 on average, so it is worth more to you despite the smaller headline. Wager-free free spins, where winnings are paid as cash up to a cap, are usually the best value of all.
Rules differ by market. In Great Britain, the Gambling Commission limits wagering requirements on promotions from UK-licensed operators to no more than 10 times the incentive amount from 19 January 2026. Compare current offers on our welcome bonuses page.
3. Solid, beneficial VIP programmes
Loyalty schemes come in two forms. Points-based programmes give everyone rewards for play: cashback, free spins or bonus money. Invitation-only VIP schemes offer account managers, higher limits and gifts to the biggest depositors.
Look for rewards with real value and no strings: cashback paid as cash without wagering, faster withdrawals, higher withdrawal limits. Be wary of rewards that require more deposits to keep a level, or bonuses with heavy wagering dressed up as gifts. Loyalty schemes are a marketing tool designed to keep customers playing. In Great Britain the Gambling Commission tightened the rules on VIP schemes from 31 October 2020, requiring operators to check that high-value customers can afford their gambling. If a VIP manager contacts you after a loss with an offer, treat it as a sales call.
4. Live customer support
You only find out how good support is when you need it, so test it before depositing. Send a question through live chat, for example about withdrawal times or verification documents, and note how fast and how specifically it is answered.
- Channels: live chat and email at minimum; some casinos add phone support.
- Hours: 24/7 chat is common; check the hours if it is not.
- Languages: English plus the casino’s main markets.
- Answers in writing: keep chat transcripts or emails. If a dispute arises, written answers are your evidence.
- Complaint procedure: the terms should explain how to complain and which dispute body you can escalate to.
A casino that cannot clearly answer “how long do withdrawals take and what documents will you need?” before you deposit is unlikely to be clearer afterwards.
5. More games, more fun, if they are the right games
A large lobby is only useful if the games come from known, licensed studios and the information is there. Check that games show their RTP in the info screen, that table games state their rules (3:2 blackjack, single-zero roulette) and that the providers are names you can look up, such as those on our gaming software hub.
Watch for RTP versions: many slots exist in several settings, and the same title can return 96% at one casino and 94% at another. If you like live games, check which live studios the casino carries and the table limits; our live dealer casinos page compares them. Demo mode, where available, lets you try games before you deposit.
Bonus check: payments and withdrawals
How a casino pays out says more about it than how it takes deposits.
- Methods: are your preferred deposit and withdrawal methods both offered? Some methods are deposit-only.
- Processing time: the terms should state how long the casino takes to approve a withdrawal, separately from the time the payment method takes.
- Limits: minimum and maximum withdrawals, and any daily, weekly or monthly caps.
- Fees: casino fees on withdrawals or currency conversion.
- Verification: which documents are needed and when. Verifying early avoids delays on your first withdrawal.
- Deposit turnover: some casinos require deposits to be wagered once (or more) before withdrawal, even without a bonus.
Our pages on casino payment methods and fast payout casinos compare methods and stated processing times.
Bonus check: safer gambling tools
A responsible casino makes it easy to control your play: deposit limits that apply immediately when lowered, loss and session limits, reality checks, time-outs and self-exclusion, all available from the account menu without contacting support. Check that these tools exist before you need them. A casino that hides them, or makes you wait days to lower a limit, is telling you something about its priorities.
How to check a casino in ten minutes
- Minute 1 to 2: scroll to the footer, note the licence number and the company name, and open the regulator’s register in a new tab.
- Minute 3: search the register for the company or licence number. Confirm the status is active and the website is listed.
- Minute 4 to 5: open the terms and find the withdrawal section: processing time, limits, fees and verification.
- Minute 6: find the complaints section and note the dispute body.
- Minute 7: open the bonus terms and write down the wagering multiple, the maximum bet and the time limit.
- Minute 8: open two or three games you know and check the RTP in their info screens.
- Minute 9: ask live chat one question about withdrawals.
- Minute 10: check the account menu (or the help pages) for deposit limits, time-outs and self-exclusion.
If any step fails, for example the licence is not on the register or support cannot explain withdrawals, move on. There are plenty of casinos that pass all ten checks without difficulty. Keep a note of what you checked and when; terms change, and a screenshot of the withdrawal rules on the day you joined is useful evidence if a dispute ever arises.
Red flags at a glance
- A licence logo that does not link to, or match, the regulator’s register.
- Terms that allow the casino to void winnings for vague reasons, or that change without notice.
- Withdrawal caps far below what the bonuses encourage you to win.
- No named dispute body.
- Bonuses with wagering above 40x on deposit plus bonus, or 48-hour time limits on large amounts.
- Pressure to deposit: repeated offers after losses, countdown timers, “last chance” messages.

Frequently asked questions
How do I know if an online casino is legit?
Find the licence number in the site footer, then look it up on the regulator’s own register and check that the company and domain match. Also read the withdrawal terms and see which independent dispute body the casino names.
What is the most important thing when choosing an online casino?
The licence and how it is enforced. A licence from a regulator that supervises its operators and offers a complaint route protects your deposits and winnings far more than any bonus.
Is a bigger welcome bonus better?
Not necessarily. What matters is the wagering requirement, the maximum bet, the time limit and which games count. A small bonus with low wagering is often worth more than a large one with 40x wagering on deposit plus bonus.
Are VIP programmes worth it?
Cashback without wagering and faster withdrawals can have real value. But loyalty schemes are designed to keep you playing; if you find yourself depositing more to keep a level, the programme is costing you money.
What should I do if a casino refuses to pay?
Complain to the casino in writing first and keep copies. If that fails, use the dispute body named in its terms or by its regulator. Curaçao’s regulator does not mediate individual disputes and refers players to certified ADR bodies; the Malta Gaming Authority points players to ADR providers such as eCOGRA.
Can I play at a casino that is not licensed in my country?
It depends on your country’s law. In Great Britain, only operators licensed by the Gambling Commission may offer gambling to British residents, and GAMSTOP only covers those sites. Other countries have their own rules; check them before you register.
