How Do Blackjack Side Bets Work? A Step-by-Step Guide
Placing a side bet is a simple addition to the standard flow of a blackjack hand. Here’s exactly how it works, from sitting down to cashing out.
- Find a Table: Choose a blackjack table, either online or in a land-based casino, that offers side bets. The available bets and their corresponding betting circles will be clearly marked on the felt.
- Place Your Main Bet: Before any cards are dealt, you must place a standard bet in the main blackjack betting area. You cannot play a side bet without playing the main hand.
- Place Your Side Bet(s): At the same time, place your chips in the designated side bet circle(s), such as “21+3” or “Perfect Pairs.” You can often play more than one side bet per hand.
- The Deal: The dealer proceeds with the hand as normal, dealing two cards to each player and two to themselves (one face up, one face down).
- Side Bet Resolution: The outcome of your side bet is determined and settled immediately based on the initial cards dealt. You can win your side bet and lose your main hand, or vice-versa. The dealer will pay out any winning side bets before the main game continues.
- Continue the Main Hand: After all side bets are settled, the main blackjack hand is played to completion according to standard rules.
The Most Popular Blackjack Side Bets Explained
While hundreds of side bets have been invented, a few have become fan favorites due to their simple rules and exciting payout potential. Here are the ones you’ll see most often.
21+3 (Also known as Top 3 / Trilux)
This is arguably the most popular side bet in the world. The name says it all: it combines the world of Blackjack (21) with Three-Card Poker (3). The bet uses your first two cards and the dealer’s up-card to see if you can form a winning three-card poker hand.
| Hand | Typical Payout |
|---|---|
| Suited Three of a Kind | 100:1 |
| Straight Flush | 40:1 |
| Three of a Kind | 30:1 |
| Straight | 10:1 |
| Flush | 5:1 |
Perfect Pairs
This is a simple and fast-paced bet on whether your first two cards will form a pair. The payout gets bigger and better depending on the quality of the pair, which can be a point of confusion for new players. Here’s the breakdown:
| Hand | Description | Typical Payout |
|---|---|---|
| Perfect Pair | Same rank, same suit (e.g., two Queens of Spades) | 25:1 or 30:1 |
| Colored Pair | Same rank, same color, different suits (e.g., Queen of Hearts, Queen of Diamonds) | 12:1 |
| Mixed Pair | Same rank, different colors (e.g., Queen of Hearts, Queen of Spades) | 6:1 |
Insurance
Insurance is a unique side bet offered only when the dealer’s face-up card is an Ace. You are betting that the dealer’s hidden card is a 10-value card, giving them a blackjack. The bet costs half of your original wager and always pays 2:1 if it wins. Critically, despite its name, it’s not a “safe” bet. With a house edge often over 7% in a standard 6-deck game, nearly all blackjack strategists recommend you never take insurance.
Other Common Side Bets
To show you the breadth of options available, here are a few other side bets you might encounter:
- Buster Blackjack: You win if the dealer busts. The payout increases based on the number of cards in the dealer’s busted hand.
- Lucky Ladies: This bet wins if your first two cards total 20. The top payouts are for getting two Queens of Hearts, especially if the dealer has a blackjack.
- Hot 3: Similar to 21+3, this bet uses your first two cards and the dealer’s up-card, but it pays based on the point total (19, 20, or 21), with the top prize for a 7-7-7 combination.
Blackjack Side Bets: Odds, Payouts, and House Edge Compared
Understanding the numbers behind side bets is key to managing your bankroll. This table shows the average house edge and hit frequency for the most popular options. Remember that these are average figures and can change based on the specific casino and its payout table.
| Side Bet | Typical House Edge | Hit Frequency (Approx.) | Why It’s Popular |
|---|---|---|---|
| 21+3 | 2.7% – 7.5% | 1 in 9 for any win | Combines Blackjack and Poker elements |
| Perfect Pairs | 2% – 11% | 1 in 13 for any pair | Simple to understand, frequent small wins |
| Insurance | ~7.4% (6 decks) | 1 in 3 (approx.) | Misleadingly seems like a “safe” bet |
| Buster | ~6.2% | Dealer busts ~28% of the time | Exciting when the dealer draws multiple cards |
The Best Blackjack Side Bet Strategy & Tips
While side bets are 100% luck, a smart approach can protect your bankroll and maximize your enjoyment. Here is the best strategy for playing them responsibly.
- Acknowledge the Math: The number one strategy is to understand that all side bets have a high house edge and are designed to favor the casino. From a purely optimal, long-term perspective, the best strategy is to not play them.
- Treat it as Entertainment: If you do play, view the cost of the side bet as a payment for entertainment and the thrilling chance at a big win, not as a reliable way to make a profit.
- Keep Wagers Small: Your side bet wager should always be a small fraction of your main bet. Sticking to the table minimum ($1 or $5) is a great rule of thumb to protect your bankroll.
- Set a Side Bet Budget: Before you start playing, decide on a specific, small amount of your total bankroll that you’re willing to risk on side bets. If you lose that amount, stop playing them for the rest of the session.
- Know the Payout Table: Payouts can vary wildly between different casinos and even different tables. Always check the specific rules and payouts before placing a bet. An online game with a 100:1 payout is much better than one offering only 30:1 for the same hand.
- Don’t Chase Losses: This is a golden rule of all gambling. Never increase the size of your side bets to try and win back money you have lost. This is the fastest way to deplete your bankroll.
Are Blackjack Side Bets Worth It? The Pros and Cons
This is the ultimate question for most players. The answer depends entirely on your goals. Here’s a direct comparison to help you decide.
Pros:
- High Payout Potential: This is the main attraction. A small $5 bet can instantly turn into a $250 or even $500 win on a lucky hand.
- Increased Excitement: Side bets add a lottery-style thrill to every hand, giving you something to root for even if your main hand is weak.
- Breaks Monotony: For players in a long session, side bets can make the standard grind of blackjack more engaging and varied.
Cons:
- Very High House Edge: This is the crucial downside. They significantly increase the casino’s overall mathematical advantage against you.
- Fast Bankroll Drain: Even though the bets are small, frequent losses add up quickly and will deplete your funds much faster than playing standard blackjack alone.
- No Skill Involved: Unlike the main game where you can use basic strategy, you have zero control over the outcome of a side bet. It is pure chance.
Conclusion: For serious players focused on optimal strategy and maximizing long-term returns, side bets are not worth it. For casual players seeking extra fun, a shot at a jackpot, and more excitement, they can be an entertaining addition if played responsibly with a strict budget.

Common Mistakes to Avoid
Players new to side bets often make the same costly errors. Avoid these common pitfalls to protect your chips and have a better experience.
- Betting Too Much: Wagering a significant portion of your stack on a high-risk, high-reward bet is a recipe for disaster. Keep side bets small.
- Ignoring the Rules: Assuming the 21+3 or Perfect Pairs payouts are the same at every casino. Always check the felt for the specific pay table.
- Thinking It’s a “Smart” Bet: Believing that side bets can be beaten with a strategy or that they are connected to the skill of the main game. They can’t be.
- Chasing: Doubling your side bet amount after a series of losses in an attempt to get “even.” This rarely works and often leads to bigger losses.
- Routinely Taking Insurance: Making this high house edge bet on a regular basis is one of the biggest leaks in an amateur player’s game.
Frequently Asked Questions (FAQ)
What is the top 3 side bet in blackjack?
“Top 3” is another common name for the extremely popular 21+3 side bet. It wins if your first two cards and the dealer’s up-card combine to form a three-card poker hand like a Flush, Straight, or Three of a Kind.
Are side bets worth it on blackjack?
From a purely mathematical and strategic standpoint, no. They all carry a high house edge that favors the casino more than the base game. However, they can be “worth it” for players who prioritize entertainment and the chance for a large payout from a small stake, as long as they are played responsibly.
How often do side bets hit in blackjack?
This varies greatly depending on the specific bet. For Perfect Pairs, the odds of getting any winning pair are about 7.4%, or roughly 1 in every 13 hands. For 21+3, the odds of getting a high-paying hand like a Straight Flush are much lower, often less than 1%.
What’s the Perfect Pairs side bet?
Perfect Pairs is a simple side bet that your first two cards will be a pair. You receive a higher payout for a “colored pair” (same rank and color, e.g., 8 of Hearts and 8 of Diamonds) and the highest payout for a “perfect pair” (two identical cards, e.g., two Jacks of Clubs).
Can I play blackjack side bets for free online?
Yes. Most reputable online casinos offer a “demo mode” or “free play” version of their digital blackjack games. This is an excellent way to see how side bets work, learn the rules, and experience the payout frequency without risking any real money.
Responsible Gambling Reminder: Always play within your means and set limits for yourself. Side bets are a form of entertainment, not a source of income. If you feel you might have a gambling problem, please seek help from a professional organization.
