How to Choose an Online Casino

Most players sign up at the first casino that appears in a search result or ad. That is a mistake. The difference between a well-chosen casino and a random one shows up the moment you try to withdraw money, dispute a bonus, or reach customer support at 2AM.

We score casinos across 40+ criteria for a reason — no single factor tells the full story. Here is how to evaluate an online casino before you deposit a single euro.

Step 1: Check the License First

The license is the single most important factor. It determines what happens to your money if the casino runs into financial trouble, how disputes get resolved, and what regulatory standards the operator must meet.

• MGA (Malta Gaming Authority) — segregated player funds, formal ADR process, regular audits. The gold standard alongside UKGC
• UKGC (UK Gambling Commission) — same tier as MGA with stricter advertising rules
• Curaçao GCA — reformed significantly in 2023–2024. Now requires KYC, AML compliance, and operator accountability. A solid mid-tier license
• Kahnawake and Anjouan — similar tier to Curaçao, less well-known but functional
• No license — walk away. No protections, no dispute resolution, no audits

Among our reviewed casinos, Casumo holds 6 licenses, 888 Casino holds 5, and LeoVegas holds 5. Multi-licensed operators face oversight from multiple regulators simultaneously — that is an added layer of accountability.

Step 2: Look at Withdrawal Speed, Not Bonus Size

A €500 bonus means nothing if the casino takes 7 days to process withdrawals. Withdrawal speed is the most common source of player complaints, and it reveals how an operator treats its customers.

Here is how the casinos we review compare:

• Stake.com — crypto withdrawals in seconds (TRC-20/XRP) to 30 minutes (BTC)
• Bet365 — PayPal and card withdrawals in 1–4 hours
• Betfair — instant bank transfer via Trustly, Visa Direct in 1–4 hours
• Betsson — Skrill and Neteller process immediately
• 888 Casino — standard withdrawals take 4+ business days for non-VIP players

Let's say you win €500 on a Friday evening. At Bet365, that money reaches your PayPal within 4 hours. At 888 Casino, you might wait until the following Wednesday. Same win, very different experience.

Step 3: Evaluate the Game Library

Provider diversity matters more than game count. A casino with 2,000 games from 12 providers offers better variety than one with 5,000 games from 3 providers — many of which may be rebranded filler from unknown studios.

The providers to look for:

• Evolution — the undisputed leader for live casino. If a casino does not have Evolution, its live section is an afterthought
• Pragmatic Play — strong in both slots and live casino, fast release schedule
• NetEnt — classic slot titles with consistently high RTP
• Play'n GO — popular mechanics, reliable performers
• Nolimit City and Hacksaw Gaming — high-volatility specialists, growing fast

Check whether the casino carries your preferred game types. If you play Megaways slots, you need Big Time Gaming titles. If you prefer crash games, look for Spribe or Stake Originals.

Betsson leads our database with 6,153+ slots from 131+ providers. Bet365 offers 2,300+ games from 10 major studios. JackpotCity sits at just 500+ games — a noticeably smaller library.

Step 4: Read the Bonus Terms Before You Deposit

The headline bonus number is marketing. The terms determine whether you will ever see a profit from it.

Here is what to check:

1. Wagering requirement — how many times you must bet the bonus before withdrawing. 25x or lower is player-friendly. 40x+ is aggressive
2. Wagering basis — bonus only or bonus+deposit? The same 35x multiplier on bonus+deposit costs double
3. Game contributions — slots typically count 100%, but table games may count just 10%. Playing blackjack at 10% contribution turns 35x into 350x effective wagering
4. Maximum bet — usually €5 per spin while bonus is active. Exceeding it voids the bonus
5. Expiry window — 30 days is fair. 7 days is tight. 90 days (888 Casino) is generous

Let's say you deposit €100 at Casumo and claim the 10x wagering welcome bonus. You need to bet €1,000 before withdrawing — achievable in a few sessions. The same €100 at Unibet faces 50x wagering on slots and 99x on live/table games. That is €5,000 to €9,900 in required bets. Same deposit, vastly different odds of clearing.

Our wagering requirements guide breaks down the complete math, including clearance probability estimates.

Step 5: Test Customer Support Before Depositing

Open the live chat and ask a simple question: "What is the average withdrawal processing time for PayPal?" The response tells you three things: how fast they reply, how accurate the information is, and whether a human or a bot handles the conversation.

• Betsson — 24/7 live chat with approximately 30-second response times
• Unibet — 24/7 live chat averaging ~30 seconds
• 888 Casino — 24/7 multilingual support via chat, email, and phone
• Betfair — live chat available but wait times can exceed 20 minutes during peak hours

Not a dealbreaker if support is slow during your test — but if you cannot reach anyone at all, that is a warning sign. Support matters most during withdrawal disputes, and that is exactly when you need it to work.

Step 6: Check Payment Method Compatibility

Before signing up, verify the casino supports your preferred deposit and withdrawal method. Key questions:

• Does my method qualify for the welcome bonus? Skrill and Neteller deposits are frequently excluded from bonus eligibility
• Can I withdraw using the same method? Apple Pay and Paysafecard are deposit-only at most casinos — you need an alternative for cashouts
• What are the withdrawal limits? LeoVegas caps withdrawals at €20,000 per month. Some casinos have no cap
• Are there fees? Most casinos do not charge withdrawal fees, but your payment provider might

Red Flags: When to Walk Away

These warning signs indicate an operator you should avoid:

• No visible license number in the website footer
• Withdrawal complaints appearing consistently in player forums — one complaint is normal, a pattern is a problem
• Aggressive bonus pushing — pop-ups pressuring you to deposit more or reverse a pending withdrawal
• Missing responsible gambling tools — no deposit limits, no self-exclusion option, no session time reminders
• Vague or hidden terms and conditions — if the bonus T&Cs are buried three clicks deep and written in dense legal language, the operator does not want you to read them
• No customer support contact visible before registration

How Our Scoring Helps

We built the ClearCasinos scoring model so you do not have to check all of this manually. Every casino is evaluated across 40+ criteria in six weighted dimensions:

• Games & Providers (25%) — game count, provider diversity, live casino quality
• Trust & Licensing (25%) — license tier, track record, terms transparency
• Payments & Withdrawals (20%) — method count, withdrawal speed, crypto and regional support
• Bonuses & Fairness (15%) — wagering, expiry, game contributions, max bet, win caps
• Customer Support (10%) — live chat availability, response time, language support
• Mobile Experience (5%) — native app, responsive design, full game access

The overall score is a weighted average on a 1–10 scale. You can see the full methodology, weights, and calculations on our scoring methodology page.
