Type	Key Feature
Floor-based puzzle	People/items assigned to floors using "above/below" clues
Box/Parcel puzzle	Items stacked or arranged by size, weight, or colour
Comparison puzzle	Quantities (age, marks) compared without exact ranking clues

Draw the structure first (floors, boxes, table) before reading conditions in detail
Place the most definite/fixed clues first, then relative clues
Re-verify the complete solution against every condition at the end

💡 Example: 5-floor building, A on even floor, B directly above A, C on topmost floor. Testing A=4 causes B=5=C (contradiction), so A=2, B=3.
