Blackjack is a widely played casino game that can be found in both physical and online casinos across the world. In Blackjack, the player is dealt two cards with the goal of the game being to beat the dealer by getting as close to 21 points as possible, without going over. The player and the dealer can both take additional cards in the hopes of getting closer to the number 21, but if they exceed that number, they will "bust", losing the hand.
The game is often compared to Poker, however whereas Poker is a game of luck and strategy, Blackjack is mainly a game of strategy, using key numerical principles such as probability and expected return to have the greatest chance of winning.
