Denmark keeps cracking down on illegal websites, with 334 blocked in 2025

• The Danish Gambling Authority investigated 695 websites over the course of 2025
• The regulator ended up blocking 334 of those websites with 36 opting for voluntary measure
• Denmark has acknowledged that in certain cases its blocking measure did not reduce some websites' traffic

Denmark continues to target illegal gambling websites, with the country shutting down 334 such operators over the course of 2025. The Danish Gambling Authority’s latest report has detailed the action it has taken against the sector, and the results of its enforcement campaign over the last year, which resulted in court-ordered blocks.

Websites banned but regulator is also going after mirror operators

The scope of the regulator’s investigation was broader than the 334 websites that were blocked in the end, with 695 potentially unlawful operations flagged and investigated further. 36 of those websites voluntarily adjusted their offers to comply with the regulator.

While the number of blocked websites appears small, the Danish Gambling Authority has strengthened its partnership with the trade association of Danish internet service providers, Teleindustrien, which will now allow the watchdog and the trade group’s members to cooperate on blocking websites that use mirrors to restart their operations following a court-ordered block.

The mirror websites will be blocked automatically upon detection, with no further court proceedings necessary to enforce the rule. The regulator has been candid about how its enforcement steps have affected the websites targeted, with 178 of the websites blocked in June 2025 indicating a 34% drop in visitors over the following six months, although some, admittedly, did not register drops in traffic.

Danish regulator focuses on a multi-pronged approach against illegal gambling

Apart from going directly after the websites operating games of chance, the Danish Gambling Authority has similarly focused on targeting the infrastructure behind this, including affiliate websites that specifically promote these services to Danish players and refer them to illegal websites.

The regulator noted that in 2025 there has been an increase in illegal gambling promotion through mobile apps, social platforms, and streaming services, and has expedited measures to work with Apple and Google to ensure that illicit apps and other content are removed from platforms, including Meta’s.
