What this test measures
The chimp test measures working memory the way it is tested in primates. Numbered tiles appear, then the numbers vanish; you click the tiles in ascending order from memory. Each round adds one more number. Your score is the highest count you clear.
How to play
Numbers 1 to N appear on the grid, then turn blank. Click them in order from 1 upward. Clear a round and the next adds one more number.
How to improve
- Memorise positions in number order, not by scanning the grid.
- Lock in the first few before the numbers hide.
- Famous chimps beat most humans past nine — treat that as the bar.
