Chimp Test
Numbers appear scattered across the board — click them in ascending order starting from 1. The instant you hit 1, every other number turns invisible and it's all position memory from there. A wrong pick is a strike; three strikes end the run.
HOW TO PLAY
- 1Memorize where each number sits on the board
- 2Click 1 — every other number hides immediately
- 3Finish the sequence from memory; each level adds a number

About this game
Chimp Test is modeled on the classic primate digit experiment: positions are random and never overlap, everything hides after the first hit, and the whole load lands on spatial working memory. The last few numbers are where runs usually die.
A miss reshuffles the level so you can't memorize the answer, and you get three strikes before the run ends. Leaving the tab pauses and restarts the level fresh. Your score is the largest count you completed.
How scoring works
- Score = the largest number count fully completed — higher is better.
- Every level places numbers at random, non-overlapping cells, always solvable.
- A wrong pick reshuffles the level; three strikes end the run.
- Most people slip around 7–9 numbers; top chimp scores beat 9.
Frequently asked questions
Why is it called the Chimp Test?
It's modeled on the classic primate cognition experiment: scattered digits are clicked in order and everything hides after the first hit — young chimps famously outscored humans at it.
How does it work?
Numbers 1 through N appear at random spots. Click them in ascending order starting from 1; the instant you hit 1, the rest go invisible and you finish from memory. Clearing a level adds a number. A wrong pick reshuffles the level and costs a strike — three strikes end it.
Can numbers overlap or land unreachable?
No. Each level draws distinct cells from the grid, and the count never exceeds available cells — every level is completable in order.
What if I switch tabs mid-level?
The game auto-pauses and covers the board; resuming reshuffles the current level so pausing can't be used to memorize positions.
Where is my record stored?
Only in this device's browser — nothing is uploaded, no account, no global ranking. One tap on the result screen clears it.
What's a good count?
Most people clear 5–7 numbers; the best lab chimps topped 9. Tracing the positions as a route works better than memorizing digits raw.
