The objective of Blackjack is to have a hand value closer to 21 than the dealer without going over.
Each card has a value, and your goal is to make the strongest possible hand while deciding whether to take additional cards or keep your current hand. If your hand exceeds 21, you bust and lose the round.
You win if your hand is higher than the dealer's hand without going over 21, or if the dealer busts. If your hand and the dealer's hand have the same value, the round ends according to the game's tie rules.
