Test your IQ for free.
Tests designed by Christian Backlund since July 2020. (Copyright.)

Note: Do not take the IQ scores of these tests too seriously. I am merely an amateur making intelligence-challenging puzzles. If you score good on these tests it however means that you'll do good also on other IQ tests. But do not take the IQ score as your valid IQ more like if you scored good or bad. All scores above 120 means that you are intelligent. A score above 120 should be perfectly enough. Good luck and enjoy!
