Intelligence tests come and go on the internet; they are viral for a white hot moment before disappearing, often forever. Sometimes they make a comeback every so often when the hungry social media masses are craving a test of their brain capacity.

Whether you solved it – or at least think you’ve solved it – there is a Youtuber who specializes in difficult math questions and viral intelligence tests. He’s got a handy little explanation about this one and how it can work in several ways. So you may have been right, but not necessarily for the right reason. It’s pretty interesting to see how it works.
