## 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 per cent of people who took it got every question right. Yes, less than one per cent 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?
