What is the 21+3 side bet in blackjack?

The 21+3 side bet in blackjack is an attractive option for players looking to increase their winning potential. This bet, available in many casinos, focuses on the player’s first two cards and the dealer’s upcard. To win, these three cards must form a specific combination, such as a pair, three of a kind, a straight flush, or a flush. This strategy adds an extra dimension to traditional blackjack, offering an additional chance to win. It is essential to understand that this bet is settled independently of the initial stake in the blackjack game.

How does the 21+3 blackjack variant work?

The 21+3 blackjack variant combines elements of blackjack and poker, offering an enhanced experience for casino players. In this version, alongside the main blackjack wager, players can place a side bet on 21+3. This side bet is based on the player’s first two cards and the dealer’s upcard. To learn more about side bets and blackjack rules, feel free to check out our articles on side bet blackjack and blackjack rules.

To win the 21+3 bet, the three cards must form one of the recognised poker hands, such as a pair, three of a kind, flush (same suit), or straight flush (consecutive cards of the same suit). The payout varies based on the winning combination, often displayed on a payout table at the casino. This bet is entirely separate from the main blackjack wager; therefore, even if a player loses their blackjack hand, they can still win the 21+3 bet.

This variant adds an extra layer of suspense and potential rewards while requiring a distinct strategy from traditional blackjack.

Card combinations in 21+3 blackjack

In 21+3 blackjack, card combinations are crucial in determining winnings from the side bet. This game blends aspects of blackjack and poker, focusing on the player’s first two cards and the dealer’s upcard. The following combinations are typically recognised:

Flush Blackjack

Flush: Three cards of the same suit (clubs, diamonds, hearts, spades) but not in sequence.

Straight Blackjack

Straight: Three cards in sequence, but not of the same suit.

Three of kind Blackjack

Three of a kind: Three identical cards, such as three queens.

Straight Flush Blackjack

Straight flush: Three sequential cards of the same suit.

Suited Three of kind Blackjack

Suited three of a kind: Three identical cards of the same suit, the rarest and most rewarding hand.

Each combination offers a different payout, potentially increasing the player’s total winnings. It is important to note that these combinations apply only to the 21+3 side bet and do not affect the outcome of the main blackjack game.

Winning strategies for the 21+3 side bet in blackjack

21+3 blackjack is an exciting variant that combines traditional elements of blackjack and poker. To maximise your chances of winning, certain strategies are essential.

First, understanding card counting is crucial. This technique helps evaluate the remaining cards in the shoe, influencing your decisions. For example, if many high-value cards are still in play, your chances of getting blackjack (a total of 21 points) increase.

Next, mastering basic blackjack strategy is essential. This includes knowing when to double your bet (blackjack double), when to split pairs (split blackjack), and when to request blackjack insurance against a dealer’s blackjack.

The 21+3 payout line, based on your first three cards (your first two cards and the dealer’s upcard), requires a different approach. Here, the focus is on forming specific combinations such as pairs, flushes, straights, or three of a kind.

Finally, bankroll management and betting systems also play a role. Some players use progressive betting systems, where the wager is adjusted based on game progress.

21+3 blackjack vs traditional blackjack: what are the differences?

21+3 blackjack and traditional blackjack offer two distinct experiences, each with unique characteristics.

In traditional blackjack, the main objective is to achieve a total of 21 points or get as close as possible without exceeding it. Strategic decisions such as taking an extra card, standing, doubling down, or splitting pairs are at the heart of the game.

21+3, on the other hand, introduces a secondary bonus element. This optional bet focuses on the first three cards dealt: your first two cards and the dealer’s upcard. The winnings from this bet are based on the formation of specific combinations such as flushes, straights, three of a kind, or pairs. This variant adds an extra betting option, blending blackjack strategy with poker-style luck.

While traditional blackjack focuses on a pure strategy to reach 21, 21+3 enhances the experience with a poker-inspired side bet, offering variety and greater potential rewards through bonus payouts.
