About Sequence Memory
Also known as a digit span test — a classic short-term memory challenge. The average person can hold 7±2 digits in working memory. Starting at 3 digits, each correct round adds one more. You have 3 lives — how many digits can you reach?
How to Play
- A number sequence flashes on screen for 1.5 seconds per digit.
- After it disappears, type the sequence back exactly.
- Correct? Next round adds one more digit.
- Wrong? You lose a life. 3 mistakes and the game ends.
