21+3 Blackjack Side Bet Guide

The 21+3 blackjack side bet is a popular bet that combines elements of poker with traditional blackjack. This bet is based on the player’s two initial cards and the dealer’s upcard, forming a three-card poker hand. Winning combinations include flush, straight, three of a kind, straight flush, and suited three of a kind, with payouts increasing based on hand rarity. The 21+3 bet adds excitement and bigger payout potential, but it comes with a higher house edge compared to standard blackjack. While fun for casual play, it’s important to understand the odds before placing this bet regularly.

What is the Blackjack 21+3 Side Bet?

The 21+3 side bet is one of the most popular side bets for blackjack, using the player’s first two cards and the dealer’s upcard to form a three-card poker hand. Payouts vary depending on the hand, with suited three of a kind typically offering the highest reward. It’s an exciting side bet to play; however, it carries a high house edge, which means the risk is higher.

Possible Winning Hands

Possible winning blackjack hands in the 21+3 side bet include a flush (three cards of the same suit), straight (three consecutive ranks), three of a kind (three cards of the same rank), straight flush (three consecutive cards of the same suit), and suited three of a kind (identical cards in suit and rank).

Suited Trips

Suited trips in the 21+3 side bet in blackjack refer to three identical cards in both rank and suit – for example, three Queen of Hearts. It’s the rarest and highest-paying hand, typically awarding 100 to 1. Suited trips combine the features of a three of a kind and a flush, making it extremely difficult to hit.

Straight Flush

A straight flush in the 21+3 side bet is a winning hand composed of three consecutive cards of the same suit. This combination is rare and ranks just below suited trips in value. It typically pays 40 to 1, though payouts can vary by casino. The odds of hitting a straight flush are low, which is why it offers such a high payout. It’s a mix of both luck and timing.

Three of a Kind

Three of a kind in the 21+3 side bet occurs when the player’s two cards and the dealer’s upcard are all the same rank, such as three Kings. This hand is less rare than suited trips or a straight flush, but it still offers a generous payout, typically around 30 to 1. It’s a strong winning combination that significantly boosts your side bet winnings when it hits.

Straight

A straight in the 21+3 side bet is formed when the player’s two cards and the dealer’s upcard create consecutive ranks, regardless of suit. This hand usually pays 10 to 1. While not as rare as a straight flush or three of a kind, it’s still a valuable win. Straight hands offer a good balance of decent payouts and reasonable odds, making them one of the more common winning hands in 21+3.

Flush

A flush in the 21+3 side bet occurs when the player’s two cards and the dealer’s upcard are all of the same suit. The cards don’t need to be in order; only the suit must match. This is one of the more frequent winning hands and typically pays 5 to 1. While the payout is lower than the other combinations, flushes offer better odds of appearing, adding steady excitement to the game.
