First spotted on Twitter, this riddle has since become a sensation over the internet, and if you haven’t tried it yet, you are missing out!

Many people who have tried it thought they got it right at first but were surprised to find out the correct answer was something different.

The riddle in question is a simple picture of coffee flowing into mazes of containers and pipes leading into 4 coffee cups with number labels. You need to carefully assess the image to find out which coffee cup will get filled up first.

Remember, the faster you work it out, the better your observation abilities are. So, are you ready for the challenge? Well, let’s get started.

How did you perform? Were you able to get the right answer in your first attempt? Most of those who tried it could only get the correct answer after a second or third trial. But why are many people failing in their first attempt on such an easy riddle to crack? Well, they are not looking into the image closer enough to discover the problem.

Look closer. Do you recognize the problem?

From this second image, you can now see that only one cup is going to get filled. So, the cup that will get filled first is the only cup with an opening, and that’s cup number 5. Easy, isn’t it?
