2005 brought many changes to the regulation of lotteries and betting. On January 7, 2005, the Conference of Cantonal Lottery Directors approved the Intercantonal Agreement on Supervision and Licensing of, as well as Distribution of Profits from Intercantonal or National Lotteries. The agreement harmonises the licensing and supervision of the Swiss lottery and betting market. Until 2005 these activities were monitored by each canton individually. Comlot assumed its duties on July 1, 2006, which is when the fully ratified Intercantonal Agreement on Lotteries came into effect.
The Agreement between the twenty-six Swiss cantons expresses the wish of the cantons to modernize the legal and administrative context of lottery and betting market in Switzerland.
