The side bet is based on the player’s first two cards and the dealer’s face-up card. The goal is to form a three-card poker hand (straight, flush, three-of-a-kind, or straight flush) with those cards. If a player achieves any of these hands, the side bet pays out according to the odds set by the casino, which vary depending on the hand’s strength. This side bet does not affect the outcome of the main blackjack hand but offers an additional way to win.
21+3 Example
For example, if the player is dealt the 8 of hearts and 7 of hearts, and the dealer’s face-up card is the 6 of hearts, the player has a flush (three cards of the same suit), and the 21+3 side bet would win.
