What this pattern means
Three attributes (shape, colour, rotation, etc.) each take three values. They are not free — they are paired into a fixed triplet structure. For example, every red cell also has a triangle and a 90° rotation. Once you spot the locked groupings, the missing cell follows automatically.
How to spot it
- Three attributes vary, but certain combinations never appear.
- Visible cells partition into a small set of recurring triplets.
- Premium-tier questions; almost always Hard or Extremely Hard.
Common visual signals
- Listing the visible (attribute-A, attribute-B, attribute-C) triplets shows that only three distinct triplets recur — never nine.
- The constraint feels 'lawful' rather than free — the grid avoids mixing attributes that should be independent.
- Distractors mix attributes from different triplets, breaking the lock.
Step-by-step solving tactic
- 1List every visible (attribute-A, attribute-B, attribute-C) triplet.
- 2Confirm that only three distinct triplets appear and no impossible mixings exist.
- 3Identify which triplet the missing cell must complete.
- 4Pick the option whose triplet matches.
Common traps
- Treating the attributes as independent — distractors will exploit this.
- Picking an option whose attributes are individually correct but whose triplet doesn't match.
- Missing the dependency when only two attributes are obviously locked but a third also is.
