How to Play
- Watch the number
A number appears on screen for a few seconds.
- Hold it in mind
The number disappears — keep it in your head.
- Type it back
Enter the digits in order, then take on a longer one.
Number Memory
A number appears for a few seconds, then vanishes. Type it back from memory. Every round adds one more digit to remember.
Ready to test your number memory?
Memorize the number while it is on screen, then type it back once it disappears. Each round adds another digit.
Type the number exactly as it appeared. One wrong digit ends the round.
What It Challenges
- Short-term memory
Hold information in mind with nothing to look at.
- Attention to detail
A single wrong digit is the difference.
- Mental rehearsal
Find your own way to keep the digits alive.
