No, blackjack is not purely a game of luck. While luck plays a role in the cards you are dealt, blackjack is primarily a game of skill and strategy. The decisions you make, such as when to hit, stand, double down, or split, directly impact your chances of winning. Basic strategy, which provides optimal decisions for every situation, can significantly reduce the house edge and improve your odds of winning over the long term. Skilled players who consistently make the right choices can gain an advantage and win more often than those who rely solely on luck.
