Memory Grid
Memorize the highlighted squares and repeat the pattern.
What this tool does
The grid lights up a sequence of cells that you must remember and repeat. Each successful round increases the challenge, making it useful for tracking your own progress in spatial recall rather than comparing scores across different devices.
How to use it

A pattern of squares lights up and you must repeat it from memory. Levels advance as you get them right.
Does it measure my memory?
