How the test works
- Squares on a 3×3 grid light up one at a time.
- When the pattern finishes, click the squares in the same order.
- Each level repeats the whole pattern and adds one more square to the end.
- One wrong square ends the test. Your score is the longest sequence you repeated.
What it measures
This test measures visuospatial working memory: how many steps of a pattern you can hold in mind and replay. It is similar to the Corsi block-tapping task used by psychologists. Most adults can repeat sequences of 6 to 10 steps.
What is a good score?
| Score | Better than about |
|---|---|
| 15 levels | 99% of people (top 1%) |
| 12 levels | 90% of people (top 10%) |
| 10 levels | 75% of people |
| 8 levels | 50% of people (average) |
| 6 levels | 25% of people |

Tips to improve
- Trace the path as a shape or route instead of remembering single squares.
- Group the pattern into chunks of three or four moves.
- Say the positions to yourself, for example "top left, centre, bottom right".
- Don't rush your clicks; there is no time limit while you repeat the sequence.
Frequently asked questions
What is a good score on the sequence memory test?
Reaching level 8 is about average. Level 11 or more puts you in roughly the top 15%, and level 14 or more is exceptional.
Is there a time limit when repeating the pattern?
No. You can take as long as you need, but the longer you wait the harder it is to keep the pattern in mind.
Does the pattern change each level?
No. Each level keeps the same pattern and adds one square to the end, so you only need to remember one new step each time.
