Blackjack Is Also Called "21"

[MillionBoy]

Blackjack is often referred to as "21" due to the game's objective of achieving a hand value as close to 21 as possible without exceeding it. The name "blackjack" originally came from a bonus payout for a hand containing the Ace of Spades and a black Jack (either the Jack of Clubs or Jack of Spades), which no longer exists in modern blackjack.

It is referred to as "21." This is because the goal of the game is to get a hand that is as close to 21 as possible without going over. The term "blackjack" actually refers to a specific hand, which is an Ace and a 10-value card.
