Number Memory Test
The rules in detail
You start with 3 digits. The number stays on screen for 1 second plus 0.6 seconds per digit (2.8 seconds for 3 digits, 7 seconds for 10), and never starts with 0. A correct answer adds one digit; the first mistake ends the game and shows the real number. Your score is the longest number you got right. Spaces are ignored; letters are not accepted.
Tips
- Split the number into pairs or triples and read them as bigger numbers (47 92 18).
- Most people manage around 7 digits; anything above 9 is excellent.
- Repeat the chunks to yourself until the input box appears.
