What Is the 21 3 Side Bet Blackjack?

In blackjack, the 21+3 side bet is a wager that the player’s first two cards and the dealer’s up card will form a flush, straight, three-of-a-kind, or straight flush. The odds of this happening are about 1 in 221, so it’s not a common occurrence.

However, when it does happen, it can be a very lucrative bet for the player.

PRO TIP:The 21 3 Side Bet Blackjack is an additional wager that can be placed on the first two cards of the player’s dealt hand. It pays out based on the player’s total point value and if the first two cards are a pair or suited. The payout increases with a higher total point value and/or a pair or suited combination, but only if the dealer does not have blackjack.

The 21+3 side bet pays out at odds of 9 to 1 for a flush, 12 to 1 for a straight, 25 to 1 for three-of-a-kind, and 100 to 1 for a straight flush. So if you bet $5 on the 21+3 side bet and you hit a flush, you would win $45.

The house edge on the 21+3 side bet is about 2.28%, which is higher than the house edge on most blackjack side bets.

However, it’s still lower than the house edge on most casino games. And if you hit one of the higher paying hands, such as a straight flush, the 21+3 side bet can be quite profitable.
