How to use the sequence memory test
- Press Start and watch: one of the nine squares lights up.
- Tap the same square. If you're right, the sequence plays again with one more square added.
- Keep going. The same square can come up more than once.
- One wrong tap ends the test. Your score is the longest sequence you repeated correctly, and the square you should have tapped is shown.
How long each sequence takes to watch
Each square lights for half a second with a quarter-second pause after it, so every square adds 0.75 seconds.
| Squares | Working | Time to watch |
|---|---|---|
| 4 | 4 × 0.75 | 3 seconds |
| 8 | 8 × 0.75 | 6 seconds |
| 12 | 12 × 0.75 | 9 seconds |
Tips to remember longer sequences
- Give the squares names, like numbers 1 to 9 or positions ("top left, middle, bottom right"), and say them in your head.
- Look for shapes. A sequence often traces a line or a corner you can picture.
- Break it into chunks of three or four, the same way you'd remember a phone number.
Frequently asked questions
Is this a medical memory test?
No. It's a game for fun and can't tell you anything about your health. If you're worried about your memory, speak to a doctor.
Can I play with a keyboard?
Yes. When it's your turn, use Tab to move between the squares and Enter or Space to choose one.
