## How many shapes?

Shapes—they’re simple, basic things that we learn as babies, right? They’re a piece of cake to identify, right? Well…maybe not. Lenstore has put together a series of shape identification puzzles, and they’re anything but easy—in fact, only 0.6% of people who took it got every question right. Yes, less than one percent of people aced it! Are you up for the challenge? Here’s how it works. For each puzzle, you’ll see a large shape with a bunch of lines drawn through it to form smaller shapes. Your goal is to correctly count how many of a certain type of shape are present inside the larger shape. (And it won’t be a total shot in the dark; the puzzles are multiple choice!) Ready to give it a try? And for more think-outside-the-box challenges, see if you can identify these everyday objects from their close-up pictures.
