# Odd Object Out - A Simple Puzzle

## Recommended Posts

I had a frustrating day yesterday working on a game that I have been slowly building. So at lunchtime today, I decided to try something new and different - a break from the frustration. So this is an early version:

Puzzle 1

Can you decide which is the odd object out - and why? Post below if you think you know which one and why. Objects are number 1-5.

I will post the answer later in the week perhaps with a version with more bells and whistles.

I vote for number 1 ! Do I have to explain why ?

Explanations: It's the only one that has all its traits on others objects.

#2 is the only one without a black border.

#3 is the only cylindrical.

#4 is the only one green.

#5 is the only small one.

#1 is red (like 2, 3 and 5), has black borders (like 3 and 5), and is squared (like 2 and 4). It's the odd one by NOT being odd

#3, because it is the only one that no 90 angles facing forward

Temechon - of course you do ;-)

I agree with Temechon and go with #1.

I would put the explanation like this: It's the only one out of those 5 that can not be identified by naming only one property. Every other object can be uniquely identified by its shape, border, color or size. If you want to describe number 1 you need to name two properties to make sure that it is described enough, I guess.

Cool!   Gryff, #4 doesn't belong, because it is the only shape that is numbered with a non-Fibonacci number.

Sesame Street, right?

One of these things just doesn't belong.

Can you guess which thing is not like the others...

before I finish my song?  I'm gonna finish my song."

Yeah!

Brilliant Temechon . But when I first looked at the puzzle - I kept thinking it was like a javascript prototype - and you are a master at those

The puzzle was originally developed by Dr. Tanya Khovanova of the MIT Math Dept. Her interests include "recreational mathematics" - whatever that might be (puzzles?).

I have posted a new puzzle here

cheers, gryff
