Swiss gambling authorities have significantly broadened their enforcement against unauthorised online gambling by adding 376 new web domains to the country’s blacklist of unlicensed betting and gaming platforms. The move underscores Switzerland’s continued efforts to limit access to offshore gambling operators and protect local consumers within the framework of its federal gambling law.
Under Swiss regulation, internet service providers are required to technically block access to gambling websites that operate without a valid Swiss licence. The list of blacklisted domains, regularly updated and published as part of official rulings, now includes hundreds of additional offshore casinos, sportsbooks, and affiliate sites that remain unauthorised under the Geldspielgesetz (Money Games Act).
Growing Blacklist Reflects Enforcement Priorities
The Eidgenössische Spielbankenkommission (ESBK) and the Intercantonal Gambling Supervisory Authority (Gespa) maintain and update multiple blacklists of unauthorised platforms that are prohibited from serving Swiss players. Any website that accepts wagers from Swiss residents without a licence or conceals its operator’s jurisdictional identity is subject to blocking.
Swiss law requires that operators seeking to offer online casino games must either be licensed Swiss entities or, in the case of land‑based casinos, receive an extension of their licence to include online offerings. Foreign operators that fail to obtain authorisation are added to the blacklist, and domestic internet providers are legally obligated to ensure access is prevented via DNS and other blocking mechanisms.
Authorities regularly publish blacklist updates in the Federal Gazette, and internet service providers implement these access restrictions accordingly. Swiss residents who play on unauthorised sites are not criminally liable for accessing them; doing so remains risky and unregulated.
Regulatory and Market Context
The expanded blacklist comes amid broader enforcement activity in the Swiss gambling landscape, where regulators have periodically blocked thousands of illegal domains since the Geldspielgesetz’s anti‑gambling provisions came into full effect in 2019. Estimates suggest that thousands of such illegal sites remain blocked as authorities strive to keep the regulated market distinct from the offshore ecosystem.
Swiss regulators have also focused on updating their legal interpretations around how operators must actively prevent access by players residing in Switzerland if they wish to avoid being placed on the blacklist. This follows rulings that active exclusion measures are required beyond mere technical IP blocking to meet legal thresholds.
Impact on Players and Operators
For Swiss consumers, the expanding blacklist is intended as a consumer protection tool, reducing exposure to offshore operators that do not offer regulated safeguards. These protections include verified age and identity checks, responsible gambling tools, and compliance with anti‑money laundering standards required of licensed operators.
Operators targeting the Swiss market without proper licensing risk domain blocks, reputational damage, and enforcement actions that tighten the window for compliant market entry. The threat of being added to Switzerland’s expansive blacklist, now numbering into the thousands over several years of updates, remains a significant deterrent for unlicensed offshore gambling services.
Enforcement and Prevention Trends in Europe
Switzerland’s aggressive approach to combating illegal online gambling sits within a broader European anti‑illegal gambling drive. For example, the Netherlands Gambling Authority (KSA) has recently set out its 2026 agenda around player protection and enforcement against unauthorised gambling activities, highlighting increased regulatory focus across jurisdictions.
Elsewhere, Luxembourg has proposed draft legislation to seize illegal gambling terminals in a bid to curb unauthorised gambling access domestically, indicating a wider continental shift toward stronger enforcement.
As digital access continues to blur borders, national regulators are deploying coordinated blacklists, ISP blocking orders, and legislative reforms to safeguard regulated markets and mitigate the risks posed by unlicensed operators offering gambling products outside approved frameworks.
