Chimp Test

Memorize the number positions. Tap them in ascending order — the numbers vanish after you tap 1.

About the chimp test

The Chimp Test is inspired by Kyoto University research showing chimpanzees outperform humans at short-term spatial number recall. Numbers appear on a grid — memorize their positions, then tap them in ascending order after they blank out. Each level adds one more number.

How it works

  1. 1Numbered tiles appear on a grid — memorize their positions.
  2. 2After you tap the first number, the rest turn blank.
  3. 3Tap the remaining tiles in ascending numerical order.
  4. 4Three strikes end the run. Your highest number is your score.

Tips to improve

  • Glance at the whole grid first — don't fixate on the '1'.
  • Encode number positions as a rough path or shape.
  • Say the coordinates silently to reinforce spatial memory.
  • Blink between rounds to clear afterimages.

Frequently asked questions

Why is it called the Chimp Test?

A famous 2007 study showed young chimpanzees outperform adult humans on this exact task — they recall number positions almost photographically.

What is a good chimp test score?

Reaching level 10 is above average. Level 15+ is an excellent score — most people find it very difficult to reach.

How is this different from number memory?

Number memory tests verbal digit span (remembering a sequence). Chimp Test measures spatial recall of numbered positions.
