In reality, there is no specific age limit for players in Brazil. However, it is important to remember that all regions governed by Brazilian law must have a clear policy on whether or not to allow gambling.
However, some regions of the country have specific policies regarding age limits for gambling. For example, in São Paulo, the 2015 law only allows live gambling games such as casino, poker, blackjack and roulette to players over 21 years of age. However, many of the other regions of the country still have different policies, and it is always recommended to check local rules before signing up at a local casino.
Finally, it is worth highlighting that gambling is regulated and controlled by the Brazilian government. Therefore, it is important to make sure you are playing at a legal and trustworthy casino.
