Digit Memory 🧠
A number appears for a few seconds. Remember it, then type it. Each round adds one more digit. How far can you go?
What is digit span?
The longest number you can repeat back is called your digit span. It's a classic measure of short-term (working) memory, the kind you use to hold a phone number, an OTP or a sum in your head. Most adults remember about 7 digits, and anything from 5 to 9 is normal.
Tricks to remember more digits
- Chunking: read 4 9 1 7 2 0 3 as "491 · 720 · 3". Three chunks are far easier than seven separate digits. This is why phone numbers are written in groups.
- Say it in your head: silently repeating the number keeps it fresh until you type it.
- Find patterns: dates, ages, pin codes or a rise-and-fall rhythm make digits stick.
