Memory Tests

Six short tests of working memory, each with one number to beat. The chimp test flashes numbered squares, hides them, and asks you to tap them in order.

Chimp TestPress Start, click or tap 1, then tap the numbers it hides in order: your biggest board is your score. Study before you tap 1 · Glance climb · Levels 7 to 9: split the route in two
Sequence Memory TestPress Start, watch the tiles flash one at a time, then click or tap them back in the same order, one flash longer every level. 8 to 10 flashes: three groups · Give every return its own word · One-slip growing sequence
Number Sequence Memory GamePress Start, read the number, then type it back once it hides, one digit longer every time you get it right. Quick-look digits · Long-look digits · Forward digits from 10
Visual Memory TestPress Start, watch a pattern of tiles light up and go dark, then click or tap the same tiles back from memory, in any order. 7 by 7 grid: patterns of 18 to 24 tiles · Store the simpler picture, lit or dark · Up-down mirror pattern climb
Photographic Memory TestPress Start, take one look at the lit tiles, then tap the same tiles back once the grid goes dark. Ten-second study, thirty-second wait · Even eidetic recall is not a copy · A random-dot test passed once
Pi Typing TestPress Start, then type the decimals of pi from memory until the first wrong digit, and see exactly how far you got. 98336 73362 · 86280 34825 · 89122 79381

More about these tools

Sequence memory lights a growing pattern of tiles for you to repeat. Number memory shows a longer number each round and asks for it back. Visual memory shows a whole pattern of tiles at once and asks which ones were lit. The photographic memory test gives you one look, or a long study and a wait, before you rebuild the pattern. The pi test is different: it checks how many digits of pi you can type from memory before the first slip. Scores are levels or digits reached, saved in this browser. These are games of practice and attention. They do not measure intelligence and cannot tell you anything about your health. For sums against the clock, try mental math practice.
