To play the mobile version of Blackjack, a player usually places a bet before the game begins and is then dealt two cards (face-up) and the dealer gets two cards (one of which is face-up). The player can then hit (ask for an extra card) or stand (keep the hand they have). The player must try to make a hand closer to 21 than the dealer's hand without exceeding 21. If the player's hand exceeds 21, they are said to 'bust' and the dealer will win.
After the player stands, the dealer will draw cards to their hand until they reach 17 or above. Once the dealer has reached 17 or above, they will no longer draw any cards. If the dealer busts, the player will win. If the dealer's cards total the same as the player’s, it is a ‘push’ and the bet will be returned to the player. If the player’s cards total closer to 21 than the dealer’s, then the player wins.
