Where Online Casinos Are Legal (and Where They’re Not)

To help players navigate the complex legal landscape of online casinos, we classify countries into three key categories.

Regulated countries — such as the United Kingdom, United States, Greece, and Italy — have official licensing authorities and legal frameworks that ensure player protection, fair play, and responsible gaming.

Unregulated countries — like Norway, India, and Hungary — allow access to international casinos but lack formal local oversight. Most casinos in these regions operate under offshore licenses such as Anjouan or Curaçao, which offer limited player protection compared to national regulators.

Prohibited countries — including North Korea, Turkey, and the UAE — ban online gambling entirely, and access to casino sites is often restricted or blocked.

Our system helps you discover the best online casinos using verified data provided directly by the operators. We know exactly which countries each casino accepts and where it is legally available

How We Rank Online Casinos

We rank online casinos based on real traffic and player activity. This means you see which brands are genuinely popular and trusted by players worldwide — not just who spends the most on advertising. Our rankings are transparent and unbiased, focusing on actual user engagement and reliability.

Licensed and Legal in Your Country

Our smart system adapts to your location, showing only casinos that are legally available in your region.

We constantly process official records from licensing authorities worldwide to keep track of:

  • Newly issued licenses for regulated casinos

  • Suspensions and revocations of dishonest operators

  • The number and type of licenses each casino holds

  • The specific markets and jurisdictions where each license is valid

This way, you always see a reliable list of licensed casinos that are safe and compliant with the rules of your country.

Our Mission: Protecting Players From Scams

Fake games and dishonest operators are everywhere. As experts in slot machines and casino games, we carefully verify the authenticity of every title and its certification by official gaming regulators. Our goal is to make sure that no casino with fake or manipulated games ever makes it into our listings.

We collaborate with hundreds of game providers and closely track the industry — knowing exactly who the established giants are and who the emerging newcomers. This allows us to rank casinos with greater accuracy and objectivity, based not only on popularity but also on the quality and legitimacy of their game libraries.

Payments, Deposits & Withdrawals

We know that payment options are one of the most important factors for players. That’s why we compare the variety of available methods (Visa, Mastercard, Skrill, Neteller, bank transfer, and more), as well as deposit and withdrawal limits and the speed of transactions at each casino.

Our goal is to give you a clear picture of how fast and convenient it is to move your money in and out, so you know exactly what to expect before you start playing.

Player Reviews & Complaints

For several years we have been helping players resolve disputes with casinos by collecting complaints into a unified database. This makes Gamblescope not only a ranking system but also a platform for player voices.

We analyze the overall number and nature of complaints: casinos that receive too many unresolved issues are either removed from our listings or their ranking is lowered within our system. By doing this, we bring more transparency and fairness to the online gambling industry and ensure that player feedback has a real impact.

Transparent & Unbiased Rankings

We scan multiple trusted traffic hubs in real time to collect independent data on the actual popularity and player activity of every online casino.

Our ranking cannot be bought — no casino can pay for a higher position. We are not interested in promoting specific brands. Instead, every casino is evaluated under the same system, with a curator’s final verdict ensuring accuracy and fairness.

Growing Global Database

Our database is constantly expanding to reflect the real online casino market:

  • 1,217 casinos already listed

  • 20–30 new casinos added every week

  • Goal: 3,000 casinos by the end of this year

We track every new licensed brand, update existing profiles, and remove operators that lose credibility — keeping the database fresh, accurate, and trustworthy.

Online Casinos, 2006–2025 — A Sevenfold Expansion

Online Casinos, 2006–2025: a ~7× expansion to ~5,000 sites by 2025, driven by mobile adoption, the EU licensing wave, and a 2020 pandemic bump.

Why GambleScope?

  • Honest rankings based on real traffic and player activity.

  • Verified licenses and legal status in your country.

  • Transparent information about terms and game providers.

  • Trusted by thousands of players worldwide.

Unregulated Countries

In countries without local regulation, players often access international casinos licensed in offshore jurisdictions (such as Curaçao or Malta). While gambling is not explicitly illegal, it is not supervised by national authorities. Examples include Brazil, India, and most African markets. Players should be aware of the risks: fewer protections, weaker enforcement, and a higher chance of disputes.

The casino is entertainment – not a way to make money

Online casinos are not a means to profit, but a form of entertainment – like going to the movies or taking a trip. Play only for fun and for the experience. Don’t try to make money – the casino always wins in the long run and acts like a vacuum cleaner for your money. Never gamble under the influence of alcohol or drugs – you lose control and increase your risk. Gambling addiction is a serious dependency that can ruin your life. Play responsibly and in moderation.
