Memorize the number, then type it back
Test the limits of your short-term memory with this number sequence recall game. Starting with a single digit, the challenge progressively increases as you advance through levels. Each number sequence is displayed briefly, then you must type it back from memory. How many digits can you hold in your mind at once? For a similar challenge comparing your memory to primates, try our chimp test.
The average person can remember 7 digits (plus or minus 2), known as Miller's Law. This test helps you discover your personal digit span and track improvement over time. The display time scales with difficulty, giving you adequate time to encode longer sequences while maintaining the challenge. You can also test your spatial memory with our visual memory grid test.
Number memory is essential for everyday tasks like remembering phone numbers, PINs, and addresses. Training your digit span can improve working memory capacity, which research links to better reading comprehension, mathematical ability, and overall cognitive function. Expand your memory training with our sequence memory test for a pattern-based variant. Regular practice may help expand your natural memory limits.
