At casinos, blackjack is typically considered a 21 game. This is because the deck of cards has 21 ranks, and a blackjack hand must have at least one card of each rank.
If a player exceeds 21, the hand is considered a blackjack and the player is awarded either a point or a kickback. .
There is some debate about whether blackjack should be called 21 or not. Some people argue that the game should be played as 21, because that is how it is traditionally played at most casinos.
Others believe that the game should be played as the dealer chooses, so that players have more control over their chances of winning. Ultimately, the choice is up to the casino operator.
