Usually, a game of baccarat uses between 6 to 8 decks, depending on the variant being played. The decks contain 52 cards each, which means that there are a total of 416 cards in 8-deck variants and 312 cards in 6-deck variants.
There is also a rare 7-deck variant (364 cards in total) that's played, but it's not as common as the 6 and 8-deck variants. The odds of the game depend on the decks of cards being used, and techniques like card counting are harder to pull off because of the numerous decks involved.
Before you start playing a game of baccarat, it is important for you to learn the number of decks that will be used per game. This will allow you to plan accordingly and use the most effective strategy to get the advantage over the dealer.
