The register of domains used to offer gambling games in breach of the Act — that is the full name of the tool that has shaped access to online casinos in Poland more than anything else since 2017. It is kept by the Minister of Finance under art. 15f of the Gambling Act, and it is public and free to search. You will find it at hazard.mf.gov.pl.
For a player it is the most practical source of information on the whole market: one search settles whether Polish authorities consider a given domain to be offering games in breach of the Act. No review, and no banner reading “licensed casino”, is a substitute. The register interface is in Polish, but the search box works the same whatever language you read it in — you type a domain and get a yes or no.
How to check a domain, step by step
- Go to the register at hazard.mf.gov.pl.
- Copy the domain alone out of the address bar — no “https://”, no “www”, no path. For example example-casino.com.
- Paste it into the register’s search field and run the search.
- Read the result: a hit means the domain has been listed as offering gambling games in breach of the Act.
- Check the variants too. Operators run mirrors and backup domains (different endings, digits in the name) which are sometimes listed separately.
The register currently holds tens of thousands of entries and is topped up regularly — we do not quote an exact number, because it changes from week to week. The practical version of this walkthrough, with the traps, is in the guide what an MF register entry means.
What a listing does
| Mechanism | Who carries it out | What the player sees |
|---|---|---|
| DNS block | Telecoms providers (ISPs) | A Ministry of Finance notice instead of the casino site |
| Payment block | Payment service providers | Rejected deposits and trouble withdrawing to a Polish account |
| Indirect effect | The operator itself | A move to a new domain, and messages about the “current address” |
That last effect explains why searches like “current address”, “new site” or “mirror” carry such volume in Poland. Domains change because the previous ones were blocked.
What the register does not mean
- No entry does not equal legal. The domain may simply not have been reported yet — especially if it is new. A foreign-licensed online casino holds no Polish licence regardless.
- A listing is not aimed at the player. The register imposes duties on internet and payment providers; the player’s own position is governed separately by art. 107 of the Fiscal Penal Code.
- A listing is not a court judgment. It is an administrative act; the entity may object and seek removal.
- A DNS block does not delete the site from the internet. It restricts access from Polish connections — which in practice makes both playing and recovering funds considerably harder.
Objection and removal
An entity whose domain has been listed may lodge an objection with the Minister of Finance. If the objection succeeds, or the grounds for the entry cease to apply, the domain is removed from the register and the blocks are lifted. The procedure is administrative and runs without the player’s involvement — all that matters to a user is the state of the register at the moment they check.
Why this matters when choosing a casino
A listing changes the player’s position on three fronts at once: access (the site stops loading), money (payments are halted and a balance becomes harder to recover) and risk (the authorities have taken an unambiguous view of that site). This is why every one of our reviews states the domain’s register status together with the date it was checked — see the online casino reviews archive.
Exactly one site in Poland cannot end up in the register: Total Casino, operating under the state monopoly. The legal context for the whole mechanism is on is online gambling legal in Poland and the Gambling Act. Gambling is 18+ and can be addictive; the free helpline in Poland is 801 889 880, and support is listed on responsible gambling.
Frequently Asked Questions
Where is the MF domain register?
At hazard.mf.gov.pl. It is public, free and requires no login; the Minister of Finance keeps it under art. 15f of the Gambling Act.
How many domains are in the register?
Tens of thousands, and the number keeps rising. We do not quote an exact figure because it goes out of date within days — check the register itself for the current state.
What happens once a domain is listed?
Internet providers block access to it and redirect the user to a Ministry of Finance information page, while payment service providers halt transactions in favour of that entity.
Does the absence of a domain from the register mean the casino is legal?
No. It only means that particular domain has not been listed yet. There is one legal online casino in Poland — Total Casino, operating under the state monopoly.
Can a domain be removed from the register?
Yes. The entity may object to the Minister of Finance; if the objection succeeds or the grounds cease to apply, the domain is removed and the blocks lifted.
Is a player liable for using a listed domain?
The listing itself imposes duties on service providers, not on players. Liability for taking part in games run in breach of the rules comes separately from art. 107 of the Fiscal Penal Code. This is not legal advice.
