Interesante (cuál es el intruso) que me llega vía @ParaDoppler@twitter.com. ☺️

What's the difference between a strategy and an algorithm?

Find a reason that each of them don't belong!

@virtuosew is a noticing game where there is a plausible reason for each of the options, so no wrong answers - it’s all about the reasons you give. That’s a good choice and a good reason for it. 😀

@robinhouston this was one of his suggested answers!

(, in case you don’t know it, is the game where it could be any of them and it’s all about the reasons.)

@Mathforlove
Bottom right is only one not equal to 5/6
Top left uses only concave polygons (& only one w/hexagons) [& only one whose 1/6 "units" nest -- so connecting 2 vertices crosses another piece.]
Top right 2 colors (also has concave, but mixed w/convex; its 1/6 units are convex.)

@norztech The great thing about is that you can make an argument for any answer. My 5yo says the shape in the lower right doesn't belong because it's the only one that doesn't have four-in-a-row.

I've updated my maker to prompt for image descriptions, and to show you suggested alt text for the final image.
Suggestions for a better format for the alt text are welcome!

I've made a tool for making "Which One Doesn't Belong?" pictures.

You can put text or pictures in each square, and change the colours of the background and text.
