Grid Memory Test
Memorize the highlighted cells, handle a quick symmetry check, then tap the cells back in order.
Frequently Asked Questions
Have another question? Let us know.
How does scoring work?
Your main score is recall accuracy: dots tapped back in the correct positions ÷ dots shown, across all completed rounds. Symmetry answers are shown as a separate accuracy metric.
How long do I have?
You have 5 minutes in total. Each symmetry question also has a 6-second limit — if time runs out it is marked as incorrect automatically.
What if the timer runs out?
Your result is submitted automatically. Completed rounds are scored normally and unfinished rounds are marked as time up, just like a timed screening test.
Do the rounds repeat?
No. Each attempt generates new random dot positions and new symmetry shapes, so you can practice as many times as you like.
Can I undo a tap?
Yes. While recalling, the Undo button removes your last tap so you can correct mistakes before confirming the round.

Why grid memory matters
Grid memory tasks combine visual-spatial memory, divided attention and ordered recall — the same mental processes behind reading maps, following multi-step instructions and working under distraction.
Visual-spatial memory
Holding the exact position of several dots in mind trains the working memory that supports navigation, design and learning new layouts.
Sustained focus
Each dot appears only briefly. Staying alert through the whole sequence builds the sustained attention used in detail-heavy work.
Divided attention
Answering a symmetry question between dots forces you to hold the memory while switching tasks — a core skill for real-world multitasking.
Ordered recall
Tapping cells back in the exact order strengthens serial-position memory, the foundation of following procedures correctly.
