What Is 21 3 Blackjack Side Bet?

In blackjack, the 21+3 side bet is a wager that the player’s first two cards and the dealer’s upcard 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.

The 21+3 side bet pays out at different odds depending on which hand is formed. A flush pays out at 7 to 1, a straight pays out at 10 to 1, three-of-a-kind pays out at 30 to 1 and a straight flush pays out at 40 to 1.

So, if you were to bet $5 on the 21+3 side bet and you hit a flush, you would win $35 (7 x $5). If you hit a straight flush, you would win $200 (40 x $5).

As you can see, the 21+3 side bet can be a very profitable wager if you’re lucky enough to hit one of the big hands. However, because the odds of hitting one of these hands is relatively low, it’s not a bet that I would recommend making on every hand. But if you’re feeling lucky and want to add an extra bit of excitement to your blackjack game, then by all means go for it!.
