This IQ test contains 30 questions and gives a score between 75 and 170 !
It was validated on some persons with known IQ.
For each question, you must choose the domino which is not like the others.
Three examples help you understand the rules of the test.
Example 1 / 3
The third domino is obviously the odd-one-out
Example 2 / 3
The first and third dominoes form a pair, the second and the fifth dominoes form an other pair. That's why the fourth domino is the odd-one-out.
Example 3 / 3
The fourth domino is odd because it breaks the sequence 1 2 3 4 5.
