Brain Score
A site-designed game score out of 1000, calculated from your personal bests. It is not an IQ score, population ranking or clinical assessment.
About Brain Score
How It Works
Each of the 40 scored activities uses a conversion chosen for this site to map your personal best to 0–100. Completed results are averaged, rounded and multiplied by 10. Unplayed activities are left out.
Comparing Your Results
Playing more activities changes which results contribute to the index. Device, browser and input differences also affect results. Compare your own attempts on the same setup; a higher game score does not establish improved cognitive ability.
