Frequently Asked Questions
Quick answers about controls, features, accuracy, and local browser saving.
What is the average human digit memory span?
According to George A. Miller's famous psychological principle (Miller's Law), the working memory capacity of the human brain is 7 ± 2 items (typically 5 to 9 digits). Remembering 10 or more digits places you in the top 5% of cognitive working memory.
How do memory champions remember long sequences?
Memory athletes use a technique called chunking (grouping digits into 3s or 4s, like phone numbers) or the Method of Loci (Memory Palace) where each 2-digit combination is translated into a vivid spatial image.
Does holding or pausing disqualify me?
No! Take your time when recalling the number, but do not write it down on paper if you want an accurate benchmark of your organic working memory.
