What are IQ games?
IQ games are puzzles that test the skills IQ tests measure: pattern recognition, logical deduction, spatial reasoning, working memory, and verbal reasoning. Unlike trivia, they push your ability to work through problems you have not seen before.
Regular practice with this kind of puzzle can sharpen processing speed and pattern recognition. The games here are free and instant, and cover all five domains. Each one shows your result the moment you finish. No email, no sign-up.
