Exception Rule Questions

A consistent rule holds across most of the grid. One cell is deliberately exceptional. The missing cell either follows the rule (most common) or — in the hardest variant — is the exception itself. Recognising 'which cell is wrong' is the cognitive task.

• Almost every cell obeys a simple rule (rotation, Latin square, colour cycle).
• Exactly one visible cell breaks that rule in a small but unmistakeable way.
• The break is too consistent to be a rendering artefact.

• One cell's orientation, colour, or shape differs from what the rule predicts.
• Eight cells fit; one cell almost-fits.
• The exception is the question's punchline.

1. 1Find the rule that explains most of the grid.
2. 2Identify the exception cell and note what it would have been if the rule held.
3. 3If the missing cell would extend the rule, apply the rule.
4. 4If the question is asking for the exception slot, pick the deliberately broken value.

• Treating the exception as a hint to a different rule — it's a deliberate break, not a clue.
• Picking the rule-compliant answer when the exception slot was intended.
• Missing that the exception is a property of the question, not noise.
