21+3 Blackjack Bet
21+3 blackjack side bet that first 2 player cards and dealer up card will make a 3-card poker hand. This bet is an optional one and is made before the cards are dealt. If the player places this bet, the outcome is known as soon as the cards are dealt. Just like in ordinary blackjack, players get two cards face up and dealer gets one card face up and another one face down. This is when the bet is checked and if it wins the payout is made.
