HOW SCORES WORK

A score should say what happened — nothing more.

We show task-level measurements such as correct answers, elapsed time, and response time. These describe a session, not your intelligence or health.

Compare like with like

A larger grid, longer timer, or different rule set changes the task. Personal trends only make sense across similar settings.

There is no brain age, IQ estimate, percentile, diagnosis, or global cognitive score.
