BLACKJACK CHEAT SHEET: ULTIMATE BLACKJACK STRATEGY CHART

1. What is Blackjack?

New to blackjack? Here's an introduction along with some key terms. If you're already familiar with the game, feel free to skip ahead to section 3! 

Blackjack, also known as ‘21’, is a game in which players have to try to get a hand of cards with a higher total value than the dealer’s without going over 21. 

2. What are the Rules of Blackjack?

Blackjack rules themselves are fairly simple. See below for a quick overview of blackjack rules below, or check out a more detailed rundown of how to play blackjack here. 

The Key Takeaway:

Blackjack is an easy game to pick up and learn the rules of, but without the right tools it can take forever to become a pro. To become a winning player, you need a good strategy. You need to learn how to play every possible combination of cards and have a super-sharp memory. 

That's where a blackjack cheat sheet or blackjack calculator comes in.

3. What is a Blackjack Cheat Sheet?

A blackjack cheat sheet is a quick-reference chart that tells you the best move—hit, stand, double down, split, or surrender—based on your cards and the dealer’s upcard. It helps players make mathematically optimal decisions and reduce the house edge.

• Designed using probability and basic strategy.

• Typically shows actions for hard hands, soft hands, and pair splits.

• Improves long-term odds by minimizing player mistakes.

• Best used as a learning tool or during online play.

• Not allowed at most physical casino tables.

Lucky for you, ProfitDuel experts have created the best Blackjack cheat sheet (which you can get sent direct to your inbox), ready for you to get started and begin building up your winnings.

4. Why Use a Blackjack Cheat Sheet?

A blackjack cheat sheet is your best ally at the table—whether you're new or experienced.

But why use one in the first place? Because it removes the guesswork.

Blackjack is a game of probabilities, and every move matters. A cheat sheet gives you instant access to basic strategy decisions, helping you make the mathematically best play every time. This isn’t about gut feeling—it’s about data-backed moves.

When used correctly, a blackjack cheat sheet can cut the house edge to under 1%, especially in online games. It’s also ideal for practicing strategy without memorizing complex charts right away. If you're serious about improving your odds, using a blackjack cheat sheet consistently is the smartest first step.

Combine it with a blackjack simulator, and you’ve got a powerful toolkit for smarter, faster, and more profitable play.

What Our Experts Say

"Using a blackjack cheat sheet isn’t about taking shortcuts—it’s about playing the odds the smart way. By following basic strategy, players can reduce the house edge to under 1%, especially in games where doubling down and splitting are allowed."

- Monika Kazimierczak, Casino & Matched Betting Expert at ProfitDuel

5. What Does a Blackjack Cheat Sheet do?

When people say ‘the house always wins’, they mean that casinos have a built-in advantage, so over time, they’re likely to come out on top. The "house edge" is just that slight edge that helps the casino make money.

At ProfitDuel we can help you reduce or remove that casino advantage, giving you a better shot at winning. One way a cheat sheet can help you do this is by sharpening your card recall. This involves keeping track of the cards that have been played so you can make smarter bets. 

Although we call it a ‘cheat sheet’, it isn’t really cheating- it just helps you play better. It doesn’t guarantee a win, but it can definitely help you improve your chances!

Tip: If you want to save even more time choosing the best hand to play, sign up to ProfitDuel to use our Blackjack Simulator, the market-leading blackjack calculator that instantly does the hard work for you.

6. Types of Blackjack Cheat Sheets

Not all cheat sheets are the same. In fact, there are several types of blackjack cheat sheets, each suited to different situations and player levels. Here's a breakdown:

• Basic Strategy Sheets: The most common type, showing when to hit, stand, double, or split.

• Soft/Hard Hand Sheets: Focus on whether your hand contains an Ace (soft) or not (hard).

• Card Counting Cheat Sheets: Used for more advanced play, helping you keep track of high/low cards.

• Mobile Optimized Sheets: Handy for online players using smartphones or tablets.

• Printable Cheat Sheets: Great for offline practice or as a study aid.

Understanding the differences lets you choose the right sheet for your play style. Whether you're looking to memorize blackjack strategy or just improve your short-term results, choosing the right blackjack cheat sheet gives you a clear advantage at the table.

7. How do I use a Blackjack Cheat Sheet?

To use our blackjack cheat sheet, have the chart open when playing - specifically when you are making a decision about how to play your hand. The chart will tell you whether to hit, stand, double down, or split, depending on your hand and the dealer's up card (which we’ll go into a little more in the next section).

Here’s how to get the most out of the blackjack cheat sheet:

1. Locate Your Hand in the Left Column: Find your hand in the leftmost column of the chart. This will either be your total hand value or a specific starting combination of two cards.

2. Identify the Dealer’s Upcard: Check the top row of the chart to find the dealer’s upcard.

3. Match Your Hand to the Dealer’s Upcard: Move across to the box where your hand and the dealer’s upcard intersect. This box tells you the best move for that situation.

4. Follow the Suggested Move: Depending on the chart’s recommendation, you’ll either hit, stand, split, double down, or surrender.

5. Adjust if Certain Moves Aren’t Allowed: If your game doesn’t allow doubling down or surrendering, simply hit or stand according to the chart.

6. Choose Tables with More Move Options: For the best experience, play at tables that allow doubling down and surrendering, giving you more ways to follow the chart’s strategy.

8. How Does a Blackjack Cheat Sheet Work?

A blackjack cheat sheet is a mathematical guide to optimal play, based on probabilities and expected outcomes for each possible player hand versus each dealer upcard. Using statistical analysis, the chart is designed to minimize the house edge by suggesting the best moves—hit, stand, double down, or split—for any combination of player and dealer cards.

The chart’s recommendations are derived from simulations or probability calculations that consider the likelihood of each action leading to a winning outcome. For example, if the player has a total of 16 and the dealer shows a 10, the chart might advise the player to hit, based on the fact that standing with a low probability hand is less favorable than the chance of improving it. This move recommendation is based on extensive trials, maximizing the expected value (EV) for that specific scenario.

Each cell in the chart encapsulates this optimal EV-based choice, making it a quick-reference tool that simplifies complex probabilities. By consistently following these recommendations, a player can approach the mathematically best possible strategy, reducing losses over time in relation to less optimal play.

9. What is Blackjack Basic Strategy?

‘Blackjack basic strategy’ is just the name of the most effective strategy and order of operations used in blackjack to give the bettor the best chance of winning. It is what is displayed with the help of the blackjack chart.

You don’t need to learn this to use the blackjack cheat sheet, but this basic strategy is based from a few key takeaways: 

1. Always double down on 11 unless the dealer shows an ace.
   
   
2. When the dealer’s upcard is 2-9, always double down on an initial score of ten.
   
   
3. When the dealer’s upcard is a 5- or a 6, always double down on a soft 13-18.
   
   
4. Always split aces and always split eights.
   
   
5. Never split a pair of fives or tens.
   
   
6. Never make the insurance bet.
   
   
7. If the dealer has a 2 or 3 upcard, always hit on a hard 12.
   
   
8. If the dealer shows 9,10, or ace, always hit A-7.
   
   
9. When you are dealt a pair of 2s or 3s, hit against a dealer’s 2 or 3 upcard. 
   
   
10. Always stand with a pair of 9s when the dealer shows 7.

10. Can I Use a Blackjack Cheat Sheet at the Blackjack Table?

You can keep the handy Blackjack Cheat Sheet chart open in your browser while playing online blackjack.

Refer to it to help you understand the best decisions to make and to formulate a strategy for each hand.

Eventually, as you gain experience and confidence, you might not need it anymore. But until then, having it by your side can guide you in making the right calls and moves as you play.

Note: while you can use this tool to help you while playing online blackjack, most physical casinos won’t let you bring a mobile phone to the table in person.

11. What are the Benefits of Using a Blackjack Chart?

Using a blackjack chart can give you a big advantage at the table. Here’s why:

• Reduces the House Edge: A blackjack chart helps lower the casino’s edge to less than 1% in certain versions of the game, giving you a better chance of winning.
  
  
• Makes Optimal Decisions: The chart tells you exactly when to hit, stand, double down, split pairs, or surrender, based on the cards you and the dealer have. No more guessing!
  
  
• Minimizes Mistakes: With a chart, you're less likely to make costly errors, helping you stretch your bankroll and improve your odds over the long run.
  
  
• Boosts Confidence: Knowing you’re following the best possible strategy lets you play with more confidence and stay focused on enjoying the game.
  
  
• Saves Time: Instead of hesitating over tough decisions, you can refer to the chart and keep the game moving smoothly.

Note: Even though the chart won’t make you win every hand, it definitely helps you play smarter!

What The Data Says

Recent data shows that when you use basic strategy—like the moves on a blackjack cheat sheet—the house edge in online blackjack can be as low as 0.5% to 2%, making it one of the best-value games for US players. This means your odds are significantly better than most other casino games, especially when you play smart.

12. Are there any Risks of Using a Blackjack Chart?

Yes, there are some risks to using a blackjack chart:

• Slows Down the Game: Constantly referring to the chart can slow the pace, which might frustrate other players or dealers.
  
  
• Casino Restrictions: Some casinos may not allow players to use charts at the table, or they may frown upon it.
  
  
• Over-Reliance: You might become too dependent on the chart and struggle to adapt to unique situations not covered by basic strategy.
  
  
• Distraction: Focusing too much on the chart can take your attention away from other important aspects of the game, like keeping track of cards.

Despite these risks, a chart can still be a valuable tool if used wisely.

13. What Tips Should I Follow Using a Blackjack Chart?

While a blackjack chart will do most of the heavy lifting for you, there are a few key blackjack tips you should remember when playing the game:

1. Basic Strategy is not Enough
   While using a blackjack chart can help you win occasionally, basic strategy alone won’t beat the house edge. Think of it like a rocket booster—it’ll get you started, but you need advanced techniques like card counting and betting strategies to really win long-term.
   
   
2. Memorize It Completely
   Just looking at a chart won’t cut it. To play effectively, you need to practice and fully memorize basic strategy. Winning requires more than a quick glance—it takes dedication.
   
   
3. The Chart Evolves
   As you improve, you’ll need to learn additional strategies specific to the game rules you encounter. Mastering the basics makes it easier to adapt to these variations.
   
   
4. Perfection Matters
   In blackjack, even small mistakes matter. To gain a real edge, you need to know the strategy perfectly—there’s no room for errors.
   
   
5. Use Extra Blackjack Tools
   To improve even further, make sure to take advantage of other helpful blackjack tools. These can refine your skills, improve your decision-making, and enhance your overall gameplay.

Blackjack Cheat Sheet FAQs

1. Is it legal to use a blackjack cheat sheet when playing online?
Yes, using a blackjack cheat sheet is completely legal when playing online blackjack. Most online platforms even encourage strategy tools to help beginners learn. However, physical casinos often prohibit external aids or phones at the table, so always check house rules before trying to use one in person.

2. Does a blackjack cheat sheet guarantee you’ll win?
No, a blackjack cheat sheet doesn't guarantee wins—it simply helps you make the statistically best move for every hand. Over time, this reduces the house edge and increases your chances of winning, but luck still plays a role in short-term results.

3. What’s the difference between a blackjack cheat sheet and card counting?
A blackjack cheat sheet helps you make optimal decisions based on your hand and the dealer’s card—no memory needed. Card counting, on the other hand, tracks high and low cards remaining in the deck to adjust your bets. One is legal and beginner-friendly (cheat sheet), while the other is advanced and often banned in casinos.

4. Can beginners use a blackjack cheat sheet effectively?
Absolutely. A cheat sheet is designed for all experience levels. For beginners, it eliminates guesswork and speeds up learning. With consistent use, even first-time players can follow the correct moves and understand basic blackjack strategy quickly.

5. What’s the best way to memorize a blackjack cheat sheet?
Start by focusing on patterns—like always splitting Aces and 8s, or doubling down on 11. Use color-coded charts, spaced repetition apps, or online simulators to practice. The more you use it during real or simulated play, the faster it sticks.

6. Are there different cheat sheets for different blackjack rules?
Yes. Blackjack rules vary slightly by casino or table type, affecting things like when to double or surrender. Some cheat sheets are customized for specific rulesets (like “dealer hits on soft 17” or “6-deck shoe”), so using one that matches your table’s rules gives the most accurate advice.

7. What is a hard hand vs. a soft hand in blackjack?
A “hard hand” is a total without an Ace counted as 11, while a “soft hand” includes an Ace valued as 11. For example, Ace-6 is a soft 17. Knowing this distinction matters because soft hands are more flexible, and cheat sheets treat them differently.

8. How do blackjack simulators work with cheat sheets?
A blackjack simulator lets you play virtual hands while showing the correct move—just like a cheat sheet, but more interactive. It trains your instincts by giving feedback on your choices, helping you learn faster and adapt without always looking at the chart.

9. When should I stop using a blackjack cheat sheet?
When you can consistently play without checking the chart and still make the optimal move every time, you're ready to go chart-free. Many players transition naturally by practicing with simulators or low-stakes games until basic strategy becomes second nature.

10. What’s the fastest way to improve at blackjack using a cheat sheet?
Combine three tools: start with a printable cheat sheet to learn moves, use an online blackjack simulator for practice, and track your results. Consistent use helps you learn faster, avoid common mistakes, and build confidence—all without needing advanced skills like card counting.
