Blackjack is a game of strategy that pits you against the dealer. You need to score closer to 21 points without going over.
At the beginning of the game the player and the dealer both receive two cards. You can see both of your cards, but can only see one of the dealer's cards.
Take a hit and hope the next card pushes you closer to 21, but doesn't send you over the top - or stand with the cards you have and hope that they will be enough to beat the dealer.
Or dare to double down for that big payout. You might even get lucky and automatically win with Blackjack!
