Six tests · about six minutes
Full benchmark
All six tests in order, one after another. Your scores are collected as you go and shown together at the end. Nothing is uploaded — the run lives in this browser, and you can stop after any test.
What you get
Reaction time and sequence memory are placed on distributions published in peer-reviewed research, so those two come with a percentile. The other three show your score alone, because no published norm matches how they are played here. The methodology page lists every source.
