Chimp Test
Memorize the number tiles, then tap them in order from memory.
How to play
- Numbered tiles appear at random spots on a 5×8 board. Take as long as you need to memorize them before tapping 1.
- The moment you tap 1, the rest of the numbers hide. Tap the tiles in ascending order from memory.
- Clear a round and one more tile is added. A wrong tap uses one of your 3 chances and reshuffles the round — lose all three and the game ends.

The Chimp Test is a short working-memory game: numbers appear at random spots on a 5×8 board, and as soon as you tap 1, the rest turn into blank tiles. Then you tap them in ascending order from memory alone. You start with 4 tiles, each cleared round adds one, and three mistakes end the run. The name comes from a 2007 Kyoto University study in which a young chimpanzee named Ayumu outperformed university students on a similar task.
Frequently Asked Questions
Q. How do you play the Chimp Test?
A. Tap the numbered tiles in ascending order. The numbers stay visible until you tap 1, so there is no timer for memorizing; after that the other tiles go blank and you finish from memory.
Q. How is the score counted, and when does the game end?
A. Your score is the number of tiles in the last round you cleared. Rounds start at 4 tiles and grow by one; a wrong tap costs one of your three chances and reshuffles the same number of tiles. The run ends when all three chances are gone.
Q. Do chimpanzees really have better memory than humans?
A. Not in general. In a 2007 Kyoto University study (Inoue and Matsuzawa), a young chimp named Ayumu was more accurate than university students when the numbers were shown for only about 0.2 seconds, but later studies found that people with practice can come close. This game borrows the task format, without the display time limit.
Q. What counts as a good score?
A. In this game, 12 tiles or more earns grade S, 10–11 A, 8–9 B, 6–7 C, and 5 or fewer D. These are the game's own grade bands, not population averages.
