Illegal gambling is rising, mainly among young people. We prepared the largest market analysis and a plan to do something about it.
14 July 2026

For the past few months, the same topic kept coming up in our meetings with online gambling operators. Illegal foreign casinos.
Practically every operator senses that their influence on the Czech and Slovak market is growing. Yet we felt the issue was being discussed mostly on gut feeling. Data was missing, a comprehensive overview was missing, and above all a plan for what to do about it was missing.
That is exactly why we decided to prepare our own market analysis. Not to count how many foreign casinos exist. We wanted to understand how the whole ecosystem works, who controls it, and where its weakest points are.
Young players are the most vulnerable
The debate about illegal gambling often revolves around a few blocked domains or the Ministry of Finance blacklist. The reality, however, is far more complex.
In recent years, foreign operators have learned to target Czech and Slovak players very effectively. They use localized website versions, the local currency, Telegram, Discord, YouTube, TikTok, streamers, and affiliate sites. And the most exposed group is young players.
Legal operators have very strict rules for marketing communication. Illegal operators respect no such limits. The result is a situation where a young person often encounters an illegal casino first and only later discovers that licensed operators even exist. We consider this a problem for the entire market.
What we analyzed
As part of the project, we went through more than 10,000 foreign casino and betting brands. We were not only interested in whether they have a Czech version. We analyzed, for example:
- language versions,
- availability from Czech and Slovak IP addresses,
- supported currencies,
- payment methods,
- affiliate programs,
- organic traffic,
- ownership structures,
- platforms used,
- licenses.
This created the most extensive internal database we have ever put together at Affilmaster.

What we found
The results surprised us in some respects.
- 345 foreign brands actively target the Czech or Slovak market. They offer a Czech or Slovak version, or support CZK or EUR.
- The real number is, by our estimate, 4 to 5 times higher. The limit was external data sources (Ahrefs, Similarweb), which restrict the scope of the analysis.
- A further 2,200+ brands operate in English only. For the young generation, however, that is practically no barrier today.
- Most of the market uses the same B2B platforms, the same game providers, and often the same licensing jurisdictions.
That means one thing. At first glance the market seems very fragmented. In reality, however, it is far more concentrated than it may appear.

Soft2bet as the biggest player
The most striking finding of the whole analysis is the company Soft2bet. Under its group we identified 131 different brands, roughly nine times the second-largest entity in our dataset. Its better-known brands include, for example:
- Sportaza
- Wazamba
- Neon54
- Frumzi
- Casombie
- Rabona
- ZetCasino
- Amunra
In our experience, most of these brands have a Czech version ready or directly target Czech players. Soft2bet has also appeared in several international investigative articles in recent months in connection with running unlicensed casinos.
If pressure can be built on one such operator, it can have a far greater impact than blocking individual domains.
Two new projects
We didn't want to close the whole project with an internal analysis alone. That is why two new websites were created.
Nelegalove.com
An internal B2B portal for Affilmaster clients. It contains a database of more than 10,000 brands, an overview of ownership structures, providers, licenses, filters, and recommended steps.
VíšKdeHraješ.cz and ViešKdeHráš.sk
A public educational project aimed at ordinary players. Its goal is neither to moralize nor to discourage play. We simply want to explain the difference between a legal and an illegal environment and show the risks that many players are not even aware of — in Czech and Slovak versions.
Education, not advertising. Why illegal foreign casinos are a trap.

Illegal gambling is not the problem of a single operator or a single company. It is a problem for the entire market. If we each proceed on our own, the situation will keep getting worse. At the same time, we don't think that blocking domains alone is a long-term solution — we see greater potential in a coordinated approach by the whole market. That is why we have prepared a concrete course of action that can largely be handled systematically and in bulk.
1. Notice of illegal activity
A standard notice requesting that the operator cease its activities in the Czech Republic and Slovakia within a set deadline. Otherwise, legal steps and damage claims follow. This step can be prepared systematically and sent out in bulk.
2. Pressure on the operator's partners
If the activity does not stop, the notice targets the entities without which the operator cannot function — that they are supporting illegal activity:
- Game providers — they do not want trouble or reputational damage over a market like the Czech Republic and Slovakia.
- Payment providers — the same as game providers; even crypto casinos have fiat payment gateways at the entry point.
- VISA / Mastercard — related to payment providers; we handle this as separate communication and a report.
- Licensing jurisdictions.
- Banks — identifying an offshore casino's bank is not difficult, and banks do not want problems. This is where we see the greatest potential, because everyone listed above wants good relationships with banks.
Back office
This work requires administration, most of which can now be handled systematically. We see it on three levels:
- Analysis and data — application-based collection and market controlling; this app itself hints at the direction.
- Execution and pressure — a law firm; after the analysis it will mainly be about template documents and models.
- Administration — a part-time person, outputs from the systems, notices, and a link between the legal team and the association.
Education
We can agree that education is essential, especially for young players. We have outlined a direction and a form it could take. On top of that, we see potential for a joint promotional campaign with you, our partners.
We have taken the first step. We prepared the data, mapped the market, and proposed a concrete solution. We believe that cooperation will be the most effective weapon in the fight against illegal gambling. Now is the time to act.
