Switzerland has blocked another 222 gambling domains

Switzerland has expanded its crackdown on unlicensed online gambling, with regulators adding 222 domains to their latest restriction lists. Because eight addresses appeared on both lists, the number of unique domains affected by the update is 214.

The latest lists were published on August 25 by Switzerland’s two gambling authorities. Gespa added 52 domains, bringing its blacklist to 887 addresses. The Swiss Federal Gaming Board (ESBK), which oversees online casinos, added another 170 domains, taking its list to 3,567.

Swiss internet providers are required to restrict access to the listed websites. The system uses DNS blocking, preventing users in Switzerland from directly reaching domains that regulators have identified as unauthorised. Both authorities regularly update their lists as new sites and mirror domains are identified.

Casino Sites and Affiliates Among the New Additions

The latest ESBK update puts a clear focus on online casino websites and the wider network surrounding them. Among the newly blocked casino-related domains are Spinrise, StarVegas, 20bet, Starda, Wazamba and Need for Spin.

The regulator also added the EPCAffiliates website, while numerous other affiliate domains were included in the update. This shows that the Swiss authorities are not limiting enforcement to the main casino websites themselves. Domains used to promote unlicensed casinos or attract Swiss users can also become targets.

Gespa's list follows a similar approach. Alongside several gambling operators, including N1Bet, Wintino, Golisimo, NovaJackpot, Interwetten and 20bet, the authority added a number of affiliate websites targeting Swiss users through search queries in German, French and English.

Four newly listed domains were also built around the Polymarket name and the Swiss .ch extension. The main Polymarket.com domain had already been blocked in Switzerland in November 2024, while Kalshi.com was added to the blacklist in November 2025.

What the Latest Update Means for Online Casinos

The new additions reinforce a trend that has been developing in Switzerland for years: simply changing a domain is becoming a less reliable way for an unlicensed casino to remain accessible to Swiss users.

Mirror sites, affiliate pages and alternative domains can all be identified and added to the official lists. This makes it increasingly difficult for offshore operators to maintain visibility in Switzerland through a constantly changing web presence.

For affiliates, the update is also significant. A site does not necessarily have to operate a casino itself to attract regulatory attention. If its primary purpose is to direct Swiss visitors toward unauthorised gambling services, its domain may also be blocked.

For licensed operators, meanwhile, the growing blacklist further strengthens the advantage of operating inside Switzerland's regulated framework. The Swiss system is deliberately restrictive: foreign gambling services without the required local authorisation can be excluded from the domestic online market.

The scale of the lists also suggests that blocking individual domains is no longer an isolated enforcement measure. It has become a regular part of Swiss gambling regulation, with authorities continuously monitoring and updating their lists rather than relying on a one-off crackdown.

Another Step in Switzerland's Expanding Blacklist

The latest action follows a much larger update in February 2026, when Swiss regulators added 376 domains to their restriction lists. That earlier move pushed the country's total number of blocked addresses close to the 3,000 mark and also targeted promotional and referral websites alongside gambling domains.

The August update is smaller, but its composition is notable. Rather than simply targeting a handful of major casino brands, regulators have continued to expand the net to include mirror sites, affiliate domains and websites designed specifically to attract Swiss traffic.

Taken together, the two updates show that Switzerland is maintaining steady pressure on the unlicensed gambling market. For casino operators and affiliates targeting Swiss players, the message is increasingly difficult to ignore: changing domains or relying on alternative promotional websites does not guarantee long-term access to the market.
