How it works

👀 What's going on?

When four things sit in a row, one often jumps out before you have even counted — three match and one is different. That difference can hide in a few places, so a good detective checks each one.

💡 Here's the trick

Which shape is different?

First check what kind each one is — if three are frogs and one is a lizard, the lizard is odd. If they are all the same kind, the odd one is hiding in its look: is one bigger or smaller, or a different colour, or missing a small detail the others have?

  1. 1.Check the kind — is one a different sort of thing?
  2. 2.If they all match, check the size — is one bigger or smaller?
  3. 3.Still the same? Check the colour and details — is one a different colour or missing a mark?

✍️ Try it

  1. 1. — which is odd?
  2. 2. — which is odd?

Set 1 is three circles and one triangle, so the triangle is odd. Set 2 is three small circles and one big one, so the is odd.

⚠️ Watch out

Do not pick the one you like best just because it catches your eye. Find the rule the other three share — same kind, same size, same colour — then the odd one is the one that breaks it.
