The Mega-Sena is the largest lottery in Brazil, organised by the Caixa Econmica Federal bank since March 1996.

Casino games are prohibited in Brazil. Poker, either land-based or online, is unregulated in Brazil as it is considered a game of skill and, therefore, falls outside of the scope of Decree-Law No.

Casinos have been considered illegal in Brazil and considered a criminal misdemeanour since 1946, by a decree signed by President Eurico Gaspar Dutra, who would have been influenced by his wife Carmela Teles Dutra, who was known for her strong religiosity to Catholic Church.
