What Is the 21 3 in Blackjack?

In blackjack, 21 3 is a side bet that the player’s first two cards will total 21. The odds of this happening are about 1 in 36, so it’s not a very good bet.

PRO TIP:In Blackjack, 21 3 is a special hand consisting of an Ace, a 10-value card (10, Jack, Queen or King) and any other card. It is the best hand in the game and beats all other hands.

The 21 3 side bet is found in some online casinos and in some live casinos. It’s not a very popular bet, because the odds are so poor.
