France’s gaming regulator, the Autorite Nationale des Jeux (ANJ), has unveiled an algorithm designed to better detect excessive gamblers, presenting it to licensed online operators on May 12. Built in-house and validated by a scientific committee, the tool weighs 23 indicators, covering areas such as financial movements and the activity and frequency of play over a six-month period, and sorts players into four categories ranging from recreational to clearly excessive. Its performance was measured against the Canadian Problem Gambling Index.
The ANJ said operators identified about 90,000 excessive players in 2025, while the regulator itself counted more than 600,000, or 8.7 percent of all online account holders. Those players generated 1.2 billion euros in gross gaming revenue, about 60 percent of the total, and the ANJ called the recent trends concerning. It wants operators, which are legally required to identify and support at-risk players, to use the algorithm alongside their own detection tools.
