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: Zaze, Zeze, Zize, and Zoze. Most people try to follow the pattern and guess “Zuze,” but the answer is hidden in the first sentence.

Since it says “Johnny’s father has five sons,” the fifth son is Johnny himself.
