About the gameHow Chimp Test works,
How Chimp Test works,
in short.
- Step 0114253
The numbers stay until you tap 1.
A handful of numbers appears scattered across the grid and stays put — there is no timer. Take your time to memorise where each one sits; the only rule is order, starting from 1.
- Step 02
Tap 1, and the rest hide.
The instant you tap 1, every other number turns into a blank dark tile. Now tap the blank tiles in order: 2, then 3, and on up. A single wrong tap ends the round.
- Step 03253
Spend lives, climb levels.
A failed level shows the numbers you missed in peach, costs one of your three lives, and replays with a brand-new layout. Lose all three and the run ends — your score is the highest level you completed.
Questions
Chimp Test questions, answered.
It is a working-memory test made famous by Ayumu, a chimpanzee at Kyoto University’s Primate Research Institute, who could glance at numbers flashed on a screen and tap them back in order far faster than most people. This version keeps the same idea: memorise where the numbers sit, then tap them from 1 upward once they hide.
Press Start and a few numbers appear scattered on the grid. They stay on screen with no timer, so memorise the layout. Tap 1 when you are ready — every other number hides — then tap the blank tiles in order: 2, then 3, and on up. Clear them all to advance to the next level.
That is the test. While the numbers are visible you are only memorising; tapping 1 commits you and hides the rest, so from 2 onward you are working purely from memory. It is the same one-glance challenge the famous chimp faced.
The round ends immediately — the Chimp Test allows just one mistake. The tile you tapped flashes red, the numbers you had not yet found are revealed in peach, and you lose a life. Tapping a number out of order during the memorise phase counts as a wrong tap too, because the rule is always 1 first.
You have three lives per run, shown as hearts in the toolbar. Each failed level costs one life and replays the same level with a fresh layout. When the last heart is gone, the run is over and your score is locked in.
No. Every attempt deals a brand-new random layout, so a level you just failed comes back with the numbers in different places. You cannot clear a level by memorising it across tries — each one is a fresh test.
The famous chimp, Ayumu, could hold around nine numbers at a single glance. Most people comfortably reach seven to ten before the layouts outpace their memory, so anything in that range is a strong human result — and every level beyond is genuinely impressive.
