- When it says "Your turn", tap the squares in the same order.
- Each level adds one more square to the sequence. One wrong tap ends the game. Share your level and challenge friends.
What this test measures
This is a version of the Corsi block-tapping test, used by psychologists since the 1970s to measure visuospatial working memory: how many locations in a sequence you can hold in mind at once. Most adults reach a span of about 5 to 7 in the classic test; in this game, where the sequence keeps growing from one round to the next, typical scores are around level 8 to 10, and scores in the teens are excellent.
Strategies help: some people chunk the sequence into patterns or shapes, others say positions to themselves ("top left, middle, bottom right"). Like other memory tests, scores improve with practice and are affected by tiredness, distraction and screen size. Treat it as a game and a fun benchmark rather than a medical test.

What is a good score?
Around level 8 to 9 is typical; 12 or more is very good.
Can the same square light up twice?
Yes. Squares are chosen at random, so repeats happen, just as in the classic Simon game.
Is this the same as the Simon game?
It works the same way: watch a growing sequence and repeat it, using nine squares instead of four colours.
