Can someone points out which is the odd one? My guess was E, basis on the number to shapes in each square, only E contains odd number of figure while other contains even.

For content that you did not create yourself, please provide attribution - at minimum you need to let us know where this came from, and any additional context you can provide is usually a big help to solvers.

Depending on interpretation, any of them is the odd one out:


Only one with a shape with more than 4 sides.


Only one with only one type of shape.


Only one in which some shapes do not touch each other.


Only one in which the total number of sides on all shapes is odd, assuming a circle is 1.


Only one with an odd number of shapes (as stated in the question)
or: only one in which one shape completely overlaps with another.

  • $\begingroup$ @Jordan.J.D that also assumes it's a well-written question. I think Apep's point here is that it's not. $\endgroup$ Commented Mar 28, 2018 at 16:28

    $\begingroup$ It could be that the goal of the question is not to see if the individual can find the correct answer, but which answer they find first and what that says about the way they approached the question. $\endgroup$

  • $\begingroup$ athin's answer is imo clearly the intended one, and all of these seem like reaches, albeit creative ones. Part of the puzzle for these kinds of puzzles is making a judgement about intention. You can say there's no objectively "correct" answer, and in a way that's true, but in another way it's just refusing to play a game because the rules aren't completely unambiguous. $\endgroup$

Maybe, the answer is



Count the sides. Only D has 5 sides, the others have 8.

My answer is:

E, because the circle is in front of two other shapes (the triangle and the square) whereas in all the others, each shape overlaps only one other at most.



Because the Pentagon is the only shape that doesn't appear twice.
