Four Digits to Memorize: NYT’s Secret Formula

When it comes to recalling long sequences of numbers, the task can seem daunting. However, there exists a fascinating four digits to memorize nyt technique that simplifies this process dramatically by breaking it down into manageable four-digit chunks. Let’s dive into this method, often highlighted by enthusiasts of mental agility, and discover how you can master it too.


Memory is an extraordinary but often underutilized tool. Our brains are naturally wired to recall certain types of information better than others. While names, faces, and places often stick with us, long sequences of numbers tend to slip away. But with the right technique, even lengthy number sequences can be easily remembered.

Why Four?

Why focus on four digits? Research suggests that our working memory can comfortably handle about four chunks of information at a time. This principle, often referred to as Miller’s Law, indicates that we can hold 7±2 pieces of information in our short-term memory. By chunking information into four-digit segments, we leverage this natural capacity, making it easier to remember and recall numbers.

Historical Insight

The technique of breaking down numbers into smaller segments isn’t new. It has roots in ancient memory techniques used by scholars and orators. They would often break down complex information into smaller, memorable chunks, using patterns, rhythms, and associations to recall them. This age-old method has stood the test of time, proving its effectiveness even in our modern digital age.

The NYT Technique

The New York Times, known for its wide array of puzzles and brain games, has often featured techniques to improve memory. Among these, the four-digit method stands out for its simplicity and effectiveness. Let’s explore how you can apply this method in practical scenarios.


Imagine you need to remember the number sequence: 438729154638. At first glance, this 12-digit number seems overwhelming. However, by breaking it down into four-digit segments, it becomes more manageable:

  • 4387
  • 2915
  • 4638

Instead of one long sequence, you now have three smaller segments to remember. This chunking process reduces cognitive load, making the number easier to recall.


A crucial part of the four-digit mnemonic technique is visualization. By creating a mental image for each four-digit segment, you enhance your ability to remember the sequence. Let’s break down the previous example with visual associations:

  • 4387: Imagine a clock showing 4:38 PM with a calendar date of the 7th.
  • 2915: Visualize a house number 2915 on a familiar street.
  • 4638: Picture a locker combination 46-38.

These vivid images create mental anchors, making the number segments easier to recall.


Practice is essential to mastering any mnemonic technique. Here are a few steps to get you started:

  1. Break Down Numbers: Start with shorter sequences and gradually work up to longer ones. Consistently practice breaking down numbers into four-digit segments.
  2. Create Associations: Develop strong, vivid images or stories for each segment. The more unique and personal these associations, the better.
  3. Review Regularly: Periodically review the numbers you’ve memorized to reinforce your memory.

Real-World Uses

The four-digit method isn’t just for puzzles or games. It has real-world applications in everyday life. Here are a few examples:

  • Passwords: Secure passwords often consist of long sequences of numbers and letters. By breaking them into four-digit segments, you can create strong, memorable passwords.
  • Phone Numbers: While modern smartphones store contacts, remembering key phone numbers can be useful in emergencies.
  • Banking Information: Account numbers and PINs are often lengthy. The four-digit method makes them easier to recall accurately.

Advanced Techniques

Once you’ve mastered the basic four-digit mnemonic technique, you can explore advanced methods to further enhance your memory:

  • The Method of Loci: Also known as the memory palace technique, this involves associating information with specific locations in a familiar place. You can place each four-digit segment in different rooms of your mental palace.
  • Rhymes and Rhythms: Creating a rhyme or rhythm can make the number sequences even more memorable. Think of how you remember song lyrics or poems.
  • Chunking Variations: Experiment with different chunk sizes based on your comfort level. Some may find three-digit or five-digit chunks more effective.


While mnemonic techniques are powerful, technology can also assist in memory improvement. There are several apps and tools designed to help you practice and enhance your memory skills:

  • Memory Apps: Apps like Lumosity and Elevate offer a variety of brain games and exercises, including number memory games.
  • Digital Flashcards: Tools like Anki and Quizlet allow you to create digital flashcards for practicing number sequences.
  • Virtual Memory Palaces: Some apps provide virtual environments where you can practice the method of loci and other advanced techniques.

Final Thoughts

The four-digit mnemonic technique is a simple yet powerful tool to enhance your memory. By breaking down long number sequences into manageable chunks, creating vivid mental associations, and practicing regularly, you can significantly improve your ability to recall numbers. Whether you’re solving puzzles, securing passwords, or simply wanting to boost your mental agility, this method offers a practical and effective solution.
