Chimp Test — Can You Beat a Chimpanzee's Memory?

The chimp test recreates Ayumu the chimpanzee's famous Kyoto University experiment: numbers appear scattered on a grid, you memorize their positions, then after tapping "1" the rest hide — and you must continue in order. Chimps routinely beat humans at this (reaching 9+); most adults peak at 5-7 numbers. Three strikes end the game.

Chimp Test
Memorize the numbers, then tap them in order
Chimps beat humans at this. 3 strikes and you're out.

Formula

score = highest number-count level completed
Typical human: 5-7 · Ayumu the chimp: 9+ · Exceptional: 10+

Example

Completed 3, 4, 5, 6 numbers; struck out at 7 → score = 6

How to Use

  1. 1. Press Start — numbers 1..N appear scattered on the grid.
  2. 2. Memorize every position, then tap 1 — the rest hide.
  3. 3. Continue tapping in ascending order.
  4. 4. Finish a level → one more number next round. Three mistakes end it.
