Sometimes the easiest riddles are the ones that trick us the most. This short IQ test looks simple at first, but it is designed to make people focus on the pattern instead of reading the question carefully.

The riddle says:

Johnny’s father has five sons.
The first son is Zaze.
The second son is Zeze.
The third son is Zize.
The fourth son is Zoze.

So, what is the name of the fifth son?

Most people quickly try to continue the pattern and guess something like “Zuze.” But the answer is already hidden in the first line.

It says Johnny’s father has five sons. That means one of the sons is Johnny.

Answer: The fifth son’s name is Johnny.
