Abstract Pattern Game (Raven's Style)

What are IQ games?
IQ games are puzzle challenges that test the cognitive skills measured by IQ tests — pattern recognition, logical deduction, spatial reasoning, working memory, and verbal reasoning. Unlike simple trivia games, IQ brain puzzles are designed to challenge your ability to think through novel problems you have never seen before.
Research shows that regularly engaging with IQ-style puzzles can improve processing speed and pattern recognition. The games on this page are free, instant, and cover all five major cognitive domains. Each one shows your result the moment you finish — no email or sign-up required.
