What is 21+3 in blackjack?

21+3 is a side bet that can be played in addition to the main blackjack game. In this side bet, players are betting on whether their two initial cards, plus the dealer's upcard, will form a poker hand ranking. The possible winning poker hands in 21+3 include straight flush, three of a kind, straight, and flush.

The payouts for a winning 21+3 side bet can vary depending on the casino, but typical payouts are as follows:

  • Straight Flush: 40 to 1
  • Three of a Kind: 30 to 1
  • Straight: 10 to 1
  • Flush: 5 to 1

21+3 can add an extra layer of excitement to the game of blackjack, but it is important to note that it is a purely luck-based side bet and does not affect the outcome of the main blackjack game. It is always recommended to play 21+3 in moderation and within your budget.
