About Number Memory
The Number Memory Test measures your digit span - how many numbers you can hold in working memory at once. This cognitive ability is crucial for everyday tasks like remembering phone numbers, addresses, and mental calculations. The average adult can remember 7 digits, but training can expand this capacity.
How to Play
- 1A sequence of numbers will appear on screen
- 2Memorize the numbers in order
- 3Type the sequence when prompted
- 4Each level adds one more digit
- 5The test ends when you make a mistake
Benefits
- Measure your working memory capacity
- Train digit span for practical applications
- Track memory improvement over time
- Challenge yourself with increasing difficulty
- Compare your memory with average scores
Tips for Better Scores
- Use chunking - group digits into meaningful clusters (e.g., 1234 becomes 12-34)
- Create associations with familiar numbers
- Practice visualization techniques
- Start fresh when you're alert, not tired
- Regular short sessions beat occasional long ones

Frequently Asked Questions
What is the average number memory span?
The average adult can remember 7 digits (plus or minus 2), a finding known as 'Miller's Law'. With training, many people can extend this to 10+ digits.
How does number memory relate to intelligence?
Digit span is one component of working memory, which correlates with fluid intelligence. However, it's highly trainable regardless of baseline intelligence.
Why is it harder to remember numbers than words?
Numbers lack inherent meaning and associations. Memory techniques like chunking and creating meaningful associations can help overcome this challenge.
Does age affect number memory?
Working memory capacity does decline slightly with age, but regular training can help maintain and even improve digit span at any age.
