Affiliate & Advertising Disclosure

Last updated: September 2026. In the interest of transparency, here's how IQ Challenge makes money.

Affiliate links

Some links on this site — including the brain-training recommendations on the results page — are affiliate links. That means if you click through and sign up or make a purchase, we may earn a commission at no extra cost to you. We only recommend products we think are genuinely worth a look, and a commission never influences quiz questions, scoring, or results.

Advertising

This site displays advertising, which may include ads served by third-party networks such as Google AdSense. These advertisers may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising through your browser settings or Google's Ads Settings.

Not professional advice

The IQ Challenge quiz, scores, score bands, estimated IQ values, and percentiles are provided strictly for entertainment. They are not a clinical or professional IQ assessment, and nothing on this site should be taken as psychological, medical, or educational advice. If you need a genuine cognitive assessment, please consult a licensed psychologist.
