About Testing my IQ
A free, mobile-first playground for the parts of your mind that matter — speed, memory, reasoning, and pattern recognition.
What it is
Testing my IQ is a collection of ten short, adaptive cognitive games. Each one is mapped to a broad ability from the Cattell–Horn–Carroll (CHC) model — the framework that underpins virtually every modern professional IQ assessment.
What it isn't
It is not a clinical IQ test. A real assessment requires a trained psychologist, controlled conditions, and standardised norms. Your Cognitive Index here is a personal practice score — useful for tracking your own progress, not for comparing yourself to others or making any decisions about your life.
Why it's free
Brain training shouldn't be gated. We keep the games free and ask only that you create an account if you want your scores saved across devices.
