In mobile Blackjack, also known as 21, players compete against the dealer to achieve a higher score of 21 or as close to it as possible. The difference between Blackjack and other casino card games is that the player's hand is compared to the dealer's; the game isn't about competing against other players.
Mobile Blackjack is played by at least two participants, but can include up to seven players. The dealer gives each player two cards that are randomly selected from a standard deck of 52. The cards are dealt from left to right beginning with the player on the left. The game follows a series of rounds in which the players must decide when to take a hit or when to stand; each player makes these decisions independently. The aim of the game is to get a higher score than the dealer without exceeding 21. If the player achieves a score of 21 with their first two cards, it is known as a 'Blackjack' and they automatically win.
