Visual Memory Test
In the Diem app this game is Memory Grid's Lights.
Remember which squares light up, then tap them.
The squares light up for a moment.
This is a game, not a medical or psychological test.
How the visual memory test works
Squares on the board light up together for a moment, then go dark. Tap the squares that were lit. As soon as you have marked as many squares as there were lights, your answer is checked. Get them all and you go up a level: one more light, and every few levels a bigger board, from 3 × 3 up to 8 × 8.
Miss one and the board shows what happened: a light you didn't mark gets a teal ring, and a mark where no light was gets a red ×. You lose one of your three lives and play a new board of the same level. The run ends when the third life goes.
Level 1 shows three lights, and each level adds one. The lights stay up a little longer when there are more of them: 1.2 seconds plus 0.15 seconds for each light, the same timing as Diem's Memory Grid, whose generator makes every board here. A board never lights a whole row or column.
What your level means
Your score is the level you reached: the one you were playing when your last life went. The result also says how many levels you cleared before it. There is no clock in this test, so take the time you need to answer; only the lights are timed.
You won't see an “average” level here. A fair one doesn't exist for a game played on so many screens and devices, so the number to beat is yours. Your best level is kept in this browser, and your last 10 runs show as a line under each result.
Tips for a higher level
- See a shape, not single squares. Three lights in a bent row are one L; a scattered pattern often looks like a letter or a face.
- Split the board into quarters and count how many lights fall in each before they go out.
- Mark the squares you are surest of first. Until the last mark, tapping a marked square takes the mark back.
- Don't hurry the answer. Nothing is timed once the lights are out.
- If you need a break, leave the page. The run pauses, and the board's lights show again when you go on.
FAQ
What is visual memory?
Visual memory is holding on to what you have seen, such as where things were, after it is gone from view. This game plays with one small part of it: keeping a pattern of squares in mind for a few seconds.
How does the visual memory test work?
Squares light up together, then go dark. Tap the squares that were lit. Get them all and the next level shows one more light; miss and you lose one of three lives and get a new board of the same level.
What is a good visual memory test score?
There is no fair average to give you: screens, devices and how a test is built all change the result. Your score is the level you reach, and the one to beat is your own best, kept in this browser with a line of your last 10 runs.
How can I do better at the visual memory test?
Try seeing the lights as one shape instead of single squares, split the board into quarters and count the lights in each, and mark the squares you are surest of first. Your best level shows you which way of looking works for you.
Do I need an account to play?
No. There is nothing to sign in to. Your best level and your last 10 results stay in this browser only.
