Brain Gyms guide

Non-medical disclaimer

Brain Gyms is an entertainment and practice site, not a healthcare service.

No medical or diagnostic use

The games and scores are not designed, validated, or offered to diagnose, treat, prevent, or monitor a medical or mental-health condition. They are not a substitute for advice from a qualified professional.

No IQ or standardized-test claims

A game result is not an IQ score, a standardized assessment, or an equivalent to a professional test such as the WAIS. The site does not claim that playing the games improves cognitive ability.

Session variability

Results are affected by the game rules, device, display, browser, input method, and conditions during play. Treat them only as informal records of individual game sessions.
