The man at the bottom left side of the picture is smiling. The others are way too serious!

Now that the warm-up is complete, it’s time to move on to a more challenging test. This time, you’ll be looking for a silhouette that matches the appearance of the mosquito on the left.

How quickly can you identify the correct shadow? Just imagine that you get a mosquito bite once every 10 seconds you spend looking for the right answer. This should speed things up!

While most people need at least a minute to solve this puzzle, eagle-eyed viewers managed to crack it in less than twenty seconds.
