Ksa Issues Binding Instruction to Endorphina Over Illegal Dutch Sites

Regulator Orders Supplier to Block Access

The Kansspelautoriteit (Ksa), the Netherlands’ national gambling regulator, issued a binding instruction to slot developer Endorphina on November 4, 2026. The order compels the company to take adequate measures to ensure its games do not appear on websites that are illegal in the Netherlands. The instruction specifically covers both Endorphina’s Maltese and Cypriot entities.

The Ksa board determined that Endorphina failed to take sufficient steps to keep its titles off unlicensed platforms. According to the regulator, this failure promoted unlicensed gambling, which constitutes a breach of Article 1(1)(b) of the Betting and Gaming Act (Wet op de kansspelen). The Ksa had previously announced its intention to issue this instruction in July and September 2026. On the same date as the binding instruction, the Ksa published a separate decision ordering that the instruction be made public.

Inspections Find Titles on 28 Unlicensed Sites

The decision follows a series of inspections conducted by Ksa staff over several months. Between January and February 2026, inspectors using Dutch IP addresses discovered Endorphina titles on sites operating illegally in the country. Follow-up checks conducted in June 2026 identified Endorphina games on 19 such websites.

Across the period from January to September 2026, the regulator found that Endorphina games appeared on at least 28 different unlicensed sites. In response to the initial findings, Endorphina stated in July 2026 that it had tightened its arrangements with distribution partners and implemented preventive restrictions. Despite these changes, the regulator concluded that the company had not met its obligations under Dutch law.

Endorphina Disputes Liability and Entity Scope

Endorphina has publicly disputed the regulator’s findings. The company maintains that it is a business-to-business (B2B) supplier and does not offer gambling services directly to players. Endorphina argued that its Maltese entity serves the licensed Dutch market and therefore should fall outside the scope of the instruction. The company also stated there is no proof it knowingly supplied illegal operators.

The Ksa rejected the argument regarding the distinction between Endorphina’s entities. The regulator emphasized that the binding instruction applies to the company’s operations as a whole in relation to the Dutch market. Endorphina has six weeks to lodge a formal objection to the decision. The Ksa noted that lodging an objection will not pause the company’s obligation to comply with the instruction in the meantime.

Separate Fine Issued to Operator EOD Code SRL

The action against Endorphina is part of a broader enforcement campaign by the Ksa against unlicensed gambling in the Netherlands. Three days before the instruction to Endorphina, on October 22, 2026, the Ksa issued a fine to operator EOD Code SRL. The €37 million fine targeted EOD Code SRL for offering gambling in the Netherlands through websites including Instantcasino and Skyhills.

Enforcement actions against suppliers are not unique to the Netherlands. In the United Kingdom, the Gambling Commission reached a settlement with Evolution over the supply of games to unlicensed sites. These recent moves indicate a continued focus by regulators on the distribution chain of gaming content, targeting both operators and the suppliers who provide the underlying software.
