A worked example

One question of the kind this skill is tested with, worked all the way through: the reasoning, and what the wrong answers are there to catch.

Find the rule first, then the exception

Which one of these four figures breaks the rule that the other three follow?

Four figures, three of which follow one shared rule.

  • Each figure is a single closed shape with a number of dots inside it.
  1. A white hexagon with five dots inside it
  2. A white triangle with three dots inside it
  3. A grey square with four dots inside it
  4. A grey pentagon with five dots inside it

Answer: A white hexagon with five dots inside it

How you get there

Look for what three of them share before you go hunting for what is wrong. The triangle has three sides and three dots. The square has four and four. The pentagon has five and five. So the shared rule is that the number of dots matches the number of sides. The hexagon has six sides but only five dots, so it is the one that breaks the rule.

Why the other answers tempt

Colour looks like a rule and is not one here: two figures are white and two are grey, so shading splits the set down the middle and cannot single anything out. A rule has to hold for exactly three of the four.

If they are stuck, say this

Do not start by looking for the odd figure. Find a rule that three of them obey, then test the fourth against it. If your rule only covers two, it is the wrong rule.

Now do it live in The Club

What this exercise is doing

The Club

Four of these belong to the same club. Drag them in - then put the odd one on the pedestal.

Odd-one-out puzzles hide the rule in ONE attribute, and everything else is noise. Run through them one at a time - shape, fill, how many, angle. Shape is different for all five, so it cannot be the rule. Count and angle repeat on both sides, so they cannot be it either. Only the fill lines up: four striped, one solid. Find the attribute that splits the group 4-and-1 and you have found the rule.

What to say if they get stuck

  1. Drag a card into The Club. If it belongs, it slides into a seat all by itself.
  2. One card keeps getting pushed back out. What do the four that fit have in common?
  3. Forget the shapes and how many there are - look at what is INSIDE each shape.

How identify a visual odd one out differs from the skills beside it

The same exercise practises one other skill, and telling them apart is often the difficulty rather than the exercise itself. On this page the skill is: select the figure that violates the shared visual rule, and it stops where one shared rule and one exception.

  • Compare visual attributes

    Compare shape, position, angle, number, size, or shading across figures. One named or inferable attribute change.
