Gambling is not a legal concept in accordance with Brazilian law. In fact, gambling doesn't even have a perfect translation in Portuguese. We can say that it can mean a bet or a game, involving a consideration, a prize and a chance.
Since only licensed casinos domiciled in Switzerland may offer online gaming services, access to gaming services not licensed in Switzerland by organisers that are domiciled or resident abroad is blocked (Article 86 of the Money Gaming Act).
