First, we need to understand the basic rules. Everyone starts with two playing cards, then it's the next person's turn to deal the cards, and he is also dealt two cards in his hand. However, at this time, the host will publicly display some cards on the board and finally decide whether to give Canada to himself or give up the game. When all the people have their cards, those who want to continue can only use their own extra cards to get a better result (e.g. Ace of Spades, J, Queen). Each player must then make a decision based on his appropriate total and other circumstances: if he feels that his hand is good enough, he can choose not to move and not draw any additional cards; Otherwise, if it's still possible to reach 20, you should draw that last card as soon as possible, hoping that it won't make him score more than 21. If the card boosts his score, then the player's game is over and he loses the game. And if his score is still below 21, then the player's game continues. He can't go past 21 because then he loses the whole game. That's why we say a simple formula for blackjack players to remember "don't overeat". If your total value is close to 20 or 30, then you should consider stopping and don't draw any more cards! So now the question is, how do you go about finding these free online games?
