20 minutes. Up to 10 questions.
Work out which of the four cubes can be the same cube, rotated. You can go back to earlier questions until the timer runs out.
- • Pick the most distinctive pattern as your anchor and note what borders it
- • Eliminate on what demonstrably conflicts: a rotated pattern, or one that appears twice
- • A pattern you cannot see in the question may sit on a hidden face, and that is no reason to eliminate
- • Every question is explained afterwards, right or wrong.
