You’ll hear about big blinds frequently, and there’s a lot to know about this bet. Whether you play at casinos, in poker tournaments, or in informal cash games, it’s important to be familiar with big blinds (and a few other common terms and poker rules). The big-blind bet helps make the game more interesting. At the start of each round, the big blind position rotates around the table so at some point every player will have their turn to make this forced bet. In poker games, the big blind is a mandatory bet placed by one player in each betting round.
