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. 3,688/1941 (the Misdemeanour Criminal Act of 1941  MCA). No specific regulation applies.
The regulations for sports betting and online casinos are a significant step toward Brazil's modern online gambling landscape. Casinos will also remain illegal for the time being, but further changes are expected in the coming years. I think the ban on bonus bets is an interesting decision.
