Seven things to check

Hello, and welcome to Myriora Non-verbal Reasoning! These puzzles use pictures instead of words. Almost all of them ask the same thing: what has changed? Let's learn how to spot it.

Look at two pictures. Something is different between them. It's easy to miss, so we use a checklist, and check one thing at a time.

First, the shape. A square has become a circle. Second, the size. The same shape can grow or shrink. Third, the shading. White has become black. Fourth, the number. Count the dots. Fifth, the position. The red dot has moved. Sixth, the direction. The arrow has turned. Seventh, the line style. A solid line has become dashed.

Let's try one together. What has changed between these two pictures? Here's a tip: go down the list, one thing at a time. Say the answer out loud!

The direction has changed. The arrow pointed up, and now it points down. The shape, the size and the shading all stay the same. Well done if you said direction!

Here's something that catches lots of people. Look at these two pictures. Some people see that the shape got bigger, and stop there. But the shading changed as well! So always finish the whole list.

Your turn! What has changed between these two pictures? Pick the right card. You've got eight seconds, or pause the video. Go!

Time's up! It's the number. There was one dot, and now there are three.

Quick review. Check the shape, the size and the shading. Then the number, the position and the direction. Then the line style. And always finish the list, because two things can change at once. See you next time!
