If the 21+3 Blackjack side bet is available at your table, you will place your bet in a separate area of the box next to each of the hands you are being dealt. This is from where we derive the name of the bet: 21 plus three Blackjack. With the 21+3 side bet, you will still play your main Blackjack hand and aim to reach 21, but you will also look to make a Three Card Poker hand from your hole cards and the dealer’s up card. You will find 21+3 Blackjack offered at a variety of online Blackjack tables, but most commonly in a game of standard Blackjack with six to eight decks. Based on three-card poker hand rankings, 21+3 Blackjack bets can potentially lead to much larger wins than a normal Blackjack hand.
So, what is 21+3? Besides 24, of course… In short, 21+3 Blackjack is simply a side bet that you can place alongside your main bet in Blackjack games.
