Raven Progressive Matrices were developed by John C. Raven in 1936 and have since become the most widely used measure of fluid intelligence — the ability to reason and solve novel problems independent of education or cultural background.
Unlike verbal or knowledge-based tests, each question presents a visual matrix with a missing piece. You must identify the underlying pattern and select the correct answer — no vocabulary, no trivia, no prior knowledge needed. Pure cognitive reasoning.
Each matrix follows a logical pattern.
Your task: find the missing piece.
