Worldwide IQ Challenge

Are you the most intelligent person in your hometown and do you want your neighborgs, co-workers, employers, family, friends, and the whole world to know it? Take the IQ test and make your name and score public to anyone, only if at the end of the test you wish to do so.

IQ World offers a unique opportunity to join a large community with over 155,000 members and to compete against the brightest brains on the planet. Even if you take this challenge, you won't need to make your score public until you have finished our IQ Test and your score has been revealed to you.

In order to guarantee a fair competition, we keep an eye on every single test that is being taken and we delete user accounts and test results if we detect that a specific user has not followed our given set of rules. Instructions for the challenge are provided right before the Intelligence Quotient test starts. Have fun and good luck!
