Chimp Test: tap the numbers in order once they disappear

Also known as: chimp test online, number memory test, remember numbers on screen, working memory test

Numbers from 1 to n appear in random cells on the screen. Tap 1: the other numbers are hidden, and you tap the cells in order from memory. With every correct row there are more numbers. Three mistakes end the test. Your result is free once you enter your email: we’ll show it to you and send it to your inbox.

What it trains

What the chimp test measures

The test checks your short-term visual memory for positions: you remember where each number is while they’re visible, and reproduce the order once they’re hidden. Your result is the longest row of numbers you reproduced correctly.

The name comes from studies in which chimpanzees did well at a similar memory task for positions. Adults most often reach 5 to 9 numbers. This is a guide, not a diagnosis: the result depends on attention, tiredness and memory techniques.

Method

Where the test comes from

The task of remembering where numbers are on a screen was studied in research on primate memory: chimpanzees were shown numbers that were then hidden, and the animal tapped the positions in order. After that, the format became popular as a game-style memory check.

In our version the grid has a small number of cells, and the test itself is not a scientific measurement and doesn’t replace an assessment by a specialist. It’s meant for self-observation and practice.

Questions

Frequently asked questions

How many numbers can a person remember?

Adults most often manage 5 to 9 numbers. This is a rough guide that depends on attention and memory techniques.

Why do the numbers disappear after the first tap?

That’s how memory for positions is tested: after “1”, the other numbers are invisible, and you need to reproduce the order.

What happens after a mistake?

A mistake is counted, and the round starts over with the same number of cells. Three mistakes end the test.

How can I remember better?

It helps to group numbers by where they are or to picture a path across the grid.

Is this a medical test?

No. It’s a game-style check for self-observation and for comparing your own attempts. It doesn’t diagnose anything and doesn’t replace a doctor’s advice.
