Looking for a fresh twist on your next blackjack session? The 21+3 side bet adds an extra layer to the opening deal, turning your two cards and the dealer’s upcard into a three-card poker hand.
One reason this side bet draws attention is the rare “suited trips” combination, where three cards match in value and suit — a hand that brings the largest payouts on the 21+3 paytable. Read on to learn exactly how suited trips works, what payouts to expect, and how this side bet fits alongside your main play.
What Are Suited Trips in the 21+3 Side Bet?
The 21+3 side bet is an optional wager placed in addition to your main blackjack stake and is judged using your first two cards plus the dealer’s face-up card. It treats those three cards like a mini poker hand, offering payouts for hands such as flushes, straights, three of a kind and, at the top, suited trips.
Suited trips occurs when all three cards are the same rank and the same suit — for example, three Queen of Hearts. Because that exact match is very uncommon, the payout for suited trips is higher than for other qualifying hands.
This side bet is resolved immediately after those three cards are revealed. Outcomes are determined by the card combination itself; player decisions on the main hand do not affect the 21+3 result.
How Does the 21+3 Side Bet Work in Blackjack?
You make the 21+3 wager before the round starts, either by placing a chip in the marked betting area at the table or selecting the side bet in an online game. Once the initial cards are dealt — two to the player, one face-up to the dealer — those three cards are evaluated as a poker hand.
If the three cards form a qualifying combination, the dealer pays the side bet according to the table’s paytable. If they don’t, the side bet is lost and play on the main blackjack hand continues as normal. The side bet is a single-round evaluation; it is independent of subsequent dealing or decisions.
Payouts for Suited Trips: What Can You Win?
Suited trips sits at the top of typical 21+3 paytables because it is one of the rarest possible three-card combinations. Exact payouts vary between games and operators, so it is important to check the paytable wherever you play.
Payouts for side bets are usually higher because the event is less likely to occur, but that also means the house edge on those bets is typically larger than on the main game. Be aware of this increased variance and the lower probability of winning when deciding whether to place a side bet.
Common Payouts for 21+3 Side Bets
Here are typical payout examples you might see for 21+3 hands, shown to give a sense of relative value rather than a guarantee of rates:
- Straight flush: 40 to 1
- Three of a kind: 30 to 1
- Suited trips: commonly around 100 to 1
- Straight: 10 to 1
- Flush: 5 to 1
For example, a £5 side bet with a 100 to 1 suited trips payout would return £500 plus your original stake in games that use that pay rate. Always check the specific game paytable before placing any side bet so you know the exact returns and how they compare to the house edge and probability of the outcome.
How Are Suited Trips Determined at the Blackjack Table?
After the initial deal, the dealer checks your two cards and their own upcard together to see if they form any qualifying 21+3 hand. For suited trips, the three cards must be the same rank and the same suit — for example, three 7 of Spades.
If that match appears, the payout is awarded immediately. If not, that particular side bet resolves as a loss and nothing further affects it during that round. The evaluation is automatic and based solely on the three-card combination.
If you’re curious about frequency and odds, those are driven by the number of cards in play and the particular shoe configuration, which is why paytables differ between tables and operators.
Is the 21+3 Side Bet Worth Taking?
Whether the 21+3 side bet is “worth it” depends on what you want from the game. The attraction is straightforward: a small extra stake can lead to a much larger payout if you hit a top combination like suited trips. But the trade-off is a higher house edge over time compared with regular blackjack play, so the side bet is generally a lower-expected-value option.
Players who enjoy occasional bigger payouts as a form of variety may find it adds interest to a session. Those focused purely on long-term returns usually prioritise the main blackjack strategy and view side bets as an occasional diversion. Consider your budget and how much of your session you want tied up in higher-variance wagers before deciding.
Common Myths About 21+3 Side Bets Debunked
Several misconceptions surround 21+3 wagers. One is that player skill or strategy in the main blackjack hand can change the side bet outcome; it cannot — the result depends solely on the initial three cards. Another is that past rounds influence future results; each deal is independent and does not alter the statistical chances in subsequent rounds.
Some players also believe particular betting patterns or seat choices affect outcomes; there’s no mechanism in standard dealing that would make this true. Finally, while big payouts do occur, they are infrequent — top hands like suited trips are rare, which is reflected in the higher payouts.
Understanding these facts helps set realistic expectations and keeps the side bet in its place as an optional extra.
