21+3 Blackjack Side Bet Guide

The 21+3 blackjack side bet is a popular option among Indian players, combining elements of poker with traditional blackjack. This bet is based on your first two cards and the dealer’s upcard, which together form a three-card poker-style hand. Winning combinations can include a flush, straight, three of a kind, straight flush, or suited three of a kind, with payouts increasing for rarer blackjack hands. 

Similar to other popular blackjack side bets like Perfect Pairs, the 21+3 wager adds extra excitement with higher potential payouts.

Players who want to maximise their edge should also understand proper blackjack betting strategy, as side bets and main bets require different approaches.

What is the Blackjack 21+3 Side Bet?

The 21+3 side bet is one of the most popular blackjack side bets, especially among Indian players looking for extra excitement. It uses your first two cards along with the dealer’s upcard to create a three-card poker-style hand. Payouts depend on the combination you make, with rare hands like a suited three of a kind usually offering the highest rewards.

21+3 Side Bet Rules and Payout

Below are the basic rules and payout details for the 21+3 side bet in blackjack at Casino Days, helping Indian players understand how this exciting wager works and what rewards are available:

1. Optional bet: The 21+3 bet is placed alongside your main blackjack bet, before any cards are dealt
2. Card combination: The bet is based on the player’s first two cards and the dealer’s upcard
3. Poker hands: These cards are evaluated as a poker-style hand. If they form one of the qualifying hands, the player wins the side bet
4. Qualifying hands:

• Flush (all same suit): Payout 5:1
• Straight (consecutive ranks): Payout 10:1
• Three of a kind (same rank): Payout 30:1
• Straight flush (consecutive and same suit): Payout 40:1
• Suited three of a kind (same rank and suit): Payout 100:1

1. Independent outcome: The outcome of the 21+3 bet is independent of whether the player wins or loses the main blackjack hand. This means it does not affect decisions like doubling down, splitting, or hitting in the main game.
2. Payouts: Payouts depend on the hand formed and may vary by casino
3. House edge: The 21+3 bet has a higher house edge than regular blackjack, making it riskier over time.

Note: Always check the specific rules and payout table at the online casino you’re playing, as the 21+3 side bet can vary between platforms.

Possible Winning Hands

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

Unlike baccarat’s structured third card rule, blackjack side bets like 21+3 rely entirely on the first three cards dealt.

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 them 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 card 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.
