Laws and regulation
Senegal is one of the most structured jurisdictions in West Africa.
The National Lottery operates under state mandate (LONASE), betting on races - through PMU Sénégal.
Land casinos and sports betting are allowed under licenses (including in the tourist areas of Dakar/Sali), with requirements for capital, reporting, control systems and player protection.
The age minimum is 18 +, AML/KYC is required, transaction logging and regulator access to data.
Online segment is allowed only within the limits of issued permits (for local licensees); offshore sites are considered illegal without permission, their advertising is prohibited.
Bottom line: you can legally work through licenses (or state mandates for lotto/horse racing), with strict observance of the rules of responsible play and compliance.
