Sequence Memory Test

Watch the grid light up, then repeat the order.

A free sequence memory game. Cells on a 3 × 3 grid light up one at a time, and you repeat them in the same order. You score one point for each sequence you repeat exactly. It is a memory challenge, not an assessment of memory health.

How the score works

One point for each sequence repeated in exactly the right order.

Worked example

In Entry you see 8 sequences of 3 to 6 steps. If you repeat 6 of them exactly and slip on one step in the other 2, your score is 6 / 8. A sequence with one wrong step scores zero, so the result counts only exact repeats.

Entry, Regular and Hard

Entry: 8 sequences of 3 to 6 steps at a steady pace.
Regular: 20 fixed sequences of 5 to 7 steps, with more repeated cells.
Hard: 20 fixed sequences of 7 to 9 steps shown at a faster pace, with more back-and-forth moves between neighbouring cells.

Each level has its own fixed set of items and its own score, so results are only compared within the same level. How levels are designed

Limits

Memory scores vary with attention, fatigue and practice. This activity does not assess memory health.

For education, entertainment and general self-exploration only. These activities are not medical or psychological assessments and do not diagnose, prevent or treat any condition.

Questions

How long a sequence can most people remember?

It varies a lot with attention, practice and the kind of material. Use your own results over time on the same level rather than comparing with others.

Can the same cell light up twice?

Yes. Repeats are allowed, and the Regular and Hard levels use them on purpose.

Does practice improve memory?

Practice makes you better at this task and this grid. It does not show that your memory in everyday life has changed.
