Decks in Blackjack: One, Four, Eight, or More? It’s easier to keep track of the tens and picture cards that have been in play if there are fewer decks in play, though, and it’s good to make use of that knowledge to your benefit. The fewer decks there are, the better your odds of winning become. So, how many decks of cards do casinos use? The answer is – that depends, but the good news is that each table at the casino will openly inform you of the number of decks. Well, it’s a good question and one that may help you win a little more if you know how many decks you are dealing with. Players who sit at the tables to participate in the almost-ritualistic gameplay that has been around since at least the 1400s seldom ask themselves the question of how many decks are used in blackjack. One of the most popular games out on the casino floor, blackjack is still shrouded in a fair degree of mystery.
