every score ranked against players in every country.
Your brain makes thousands of decisions a day, most of them in a few hundred milliseconds. We turned those moments into games, scores and a world ranking, so you can finally see how sharp you really are.

A better kind of break.
Mentometry is made for short, focused sessions: a minute or two of absorbing play to step away from stress,
then back to your day. It is not made for hours at a time, and we think that is the point.
Short breaks, lighter mood Early evidence
In controlled studies, casual puzzle-style games have been linked to short-term improvements in mood and lower physiological stress. The effects are modest and differ from person to person.
Practice sharpens the practiced skill Well supported
Research reviews find clear gains on the tasks people train. Whether those gains carry over to everyday life is not established, so we show you your own progress in these games and do not promise real-world results.
Moderation matters Large studies
Large studies of digital engagement suggest moderate use is not intrinsically harmful, while very heavy use shows weak links with lower well-being. That is why Mentometry is built for a few minutes at a time.
Illustration of the idea, not measured data. Moderate use tends to look best; very long sessions add little.
Please note: Mentometry is a game and an educational tool. It is not a medical, therapeutic or financial product, and it does not diagnose, treat or prevent any condition or promise better results at work or in trading. If stress feels overwhelming, please talk to a health professional.
