poker é um jogo de azar

Put simply, it's not against the rules, but it's not a particularly nice thing to do. Poker players see slow rolling as a classless act and, therefore, against the spirit of the game (see video above). That's why people don't slow roll in poker.

Slow rolling is considered a breach of poker etiquette and should be avoided in most situations, while Hollywooding is just a part of a poker strategy you could adopt.
