About Number Span
Digit-span test: a string of digits flashes up and disappears, and you type it back exactly. One digit longer each round until you slip. Your score is the longest string you returned perfectly — the classic measure of working memory.
- How to play: Type the digits, or tap the keypad, then Enter.
- A go takes about 40 seconds. The daily puzzle is identical for every player and resets at your local midnight.
- Share any score as a challenge link — whoever opens it faces the same puzzle with your number to beat.
