FAQ
Chimp Test FAQ
+ - What is the chimp test?
Numbers appear on a grid. Click them in ascending order (1, 2, 3...). After the first click, the remaining numbers hide. It is based on a famous study of visual working memory.
+ - What is a good memory score?
On level-based modes, 5-6 is casual, 7-10 is solid, and 11+ is excellent.
+ - Does practice help?
Yes. Short, regular sessions can improve focus and working memory performance over time.
+ - Does my best score save?
Yes. Personal bests for each mode and chimp grid size are saved in this browser on this device only.
+ - Which mode should I try first?
Start with the chimp test on 4×4, or try Sequence Memory if you want a simpler pattern game.
