Blackjack has been a staple of casino gaming for centuries and it is one of the most popular games in any online casino. Blackjack is a game of comparing cards between players and the dealer, with each receipt an attempt to reach a higher score than the other without going over 21. Each player is dealt two cards face up and the dealer is dealt two cards, one face up and one face down. Players and the dealer can take additional cards (hit) in an attempt to reach 21 or get closer. It is also possible to stand pat and stay with the cards already dealt. The player is allowed to split a pair into two separate hands, double down, or surrender a hand. After all players and the dealer have gone, the hand that is closest to 21 without going over (bust) wins.
