Sequence memory test

Squares on a 3×3 grid light up one after another. Tap them in the same order. Each level shows the whole sequence again and adds one square at the end.

In the Corsi block test, a similar task used in psychology, adults usually remember about 5 to 7 positions. Here the sequence repeats every level, so longer runs are possible.

Yes, it works the same way: the sequence grows by one step each level and you repeat it from the start. All squares look the same, so you remember positions, not colors.

Yes. The keys 1 to 9 match the squares row by row, from the top left to the bottom right.
