The regulator’s five-year figures also show a substantial increase in enforcement. Prohibition proceedings rose from 68 in 2022 to 287 in 2025, while around 6,300 websites were reviewed for illegal gambling or related advertising by the end of last year.
The GGL said its approach increasingly extends beyond individual gambling sites to payment providers, advertising partners, affiliate networks, hosting companies and other parts of the technical infrastructure supporting illegal operations.
The scale of that challenge was highlighted recently by a German investigation into a suspected €5.86 billion illegal online gambling network, underlining the compliance and enforcement pressures associated with high-volume unauthorised gambling activity.
By the end of 2025, the GGL said 1,843 illegal websites were no longer accessible from Germany because of prohibition measures or network blocking. Payment measures also cut 178 websites off from established payment channels.
