The European Lotteries association (EL) is the European umbrella organization of entities operating national lotteries and other games of chance, including sports betting. The members of EL are operating their services for the public benefit. EL is the largest and most representative lottery and gambling sector’s organization in Europe, present in 39 European countries with a total of 70 members, including all EU member states (50 members are in the EU and 20 non-EU member states). EL stands for the sound and sustainable activity model for the benefit of society, based on the values of forward-thinking, responsibility and integrity. EL members only operate in those jurisdictions in which they are licensed by the state and where they comply with the legal requirements (e. g. anti-money laundering, responsible gaming policies, etc), and act as the most responsible operators in each jurisdiction. In 2022, EL members secured more than €22 billion for society and directly supported valuable projects related to sport, cultural heritage, art, health care, individuals with disabilities/disadvantages, education, science and many other areas. It is estimated that around half of the European adult population annually participates in the games that are offered by the EL members
