The aim is to get a total of 21 or as close to 21 as possible (without going over) on your hand. All numbered cards are worth their face value, picture cards (J, Q, K) are all worth 10, and ace (A) can be used as 1 or 11. The dealer also starts with two cards, where you can see one of them. In its essence though, the game is very straightforward: You get dealt two cards and can after that decide if you want more cards or not. That's because this is a game where strategy and tactics are key. It is a game that is quite easy to get started with, but more difficult to become really good at.
When playing blackjack, the dealer is your only opponent and your goal is to beat him. There might be several players seated around the blackjack table, but in this game, it is all about the dealer only. Blackjack is a card game that is often found at land-based casinos.
