IQ Mosaic

A 50-question reasoning challenge across five domains, with visual matrix puzzles plus memory and speed tasks. Completely free. No ads, no sign-up, nothing tracked.

How sharp is your reasoning? IQ Mosaic is a clean, timed cognitive challenge: 50 questions in 25 minutes across five kinds of thinking, with real visual puzzles and optional memory and speed tasks.

WHAT YOU GET • 50 questions, one focused 25-minute session • Five domains: verbal, logic, quantitative, abstract, and spatial reasoning • Real visual puzzles: matrix-style 3×3 grids, figure series, and mental rotation, drawn as crisp vector graphics (not stock images) • Optional add-ons: a working-memory task (backward digit span) and a processing-speed task (symbol search), the two abilities a multiple-choice test can't measure on its own • An estimated score with its likely range, and a domain-by-domain breakdown • Review every question you missed, with the correct answer • Share a clean result card

COMPLETELY FREE The 50-question test and the full results report are free: your estimated score, your complete Cognitive Profile, and the domain-by-domain breakdown. No purchase, no subscription, no ads.

BUILT TO BE HONEST Your score is an estimate shown with a confidence range, not a clinical, diagnostic, or accredited measurement, and not a substitute for professional evaluation. Every question is original, with a single verified-correct answer and four distinct choices. Question formats are modeled on well-studied public reasoning paradigms; see how the questions are built and the research behind them at iq-mosaic.pages.dev/methodology.

PRIVATE BY DESIGN No account. No sign-up. No ads. Nothing is tracked, transmitted, or sold. Every result and setting stays on your device.

A FRESH TEST EVERY TIME Questions are drawn from a large bank with no repeats across retakes and a spread of question types, so each sitting feels new.

IQ Mosaic is for entertainment and self-improvement. It is not a clinical assessment and should not be used for any diagnostic purpose.
