Here’s the riddle: The photograph shows a hand pouring coffee into a set of chutes that each lead to one of four cups. Your goal is to determine which cup will be the first to be filled with coffee.
While that might seem a simple task at first, it has left thousands of people scratching their heads. As a matter of fact, the tweet has gone viral since it was posted, collecting nearly 2,000 retweets and over 4,000 likes.
Initially, you might be tempted to choose the cup with the shortest spout. You wouldn’t be alone; most Twitter users responded with similar answers. Others put their mathematical prowess to the test (although you don’t need to know your numbers to answer this puzzle!)
Need a hint? Take a closer look at the details in each pipe.
If you answered cup number 5, you are correct! Cup 5 will fill up first because the pipes leading to cups 4, 9, and 7 are blocked.
See? Easy! Next, prove your puzzle genius by figuring out where the turtle is in this picture.
