Multi-Floor Basic
Multi-Floor Basic puzzles involve arranging people or items on different floors of a building (typically floors 1 to 5) with each person having an additional attribute (like favorite color). You are given deductive clues including direct assignments, relative positional relationships (above/below with specific gaps), exclusionary statements, and color-floor linkages. These foundational puzzles test your ability to build a complete vertical arrangement from interconnected clues.

Prerequisites
How to Solve Multi-Floor Basic Problems
Step 1: Identify the number of floors and the attributes (e.g., persons, colors)
Step 2: Draw a vertical stack with floor numbers (1=bottom to N=top)
Step 3: Place all direct assignments (e.g., 'A lives on floor 3')
Step 4: Apply relative positional clues (e.g., 'X lives 2 floors above Y')
Step 5: Use exclusionary clues (e.g., 'X does not like color C') to eliminate possibilities
Step 6: Apply color-floor linkage clues (e.g., 'The person who likes color C lives below person D')
Step 7: Use process of elimination to complete the arrangement
Step 8: Verify all clues are satisfied
Example Problem
Example: Five people (Amit, Priya, Rohan, Sneha, Vikram) live on floors 1-5 with different colors (Red, Blue, Green, Yellow, White). Clues: Rohan lives on floor 3. The person who likes Green lives 3 floors away from Sneha. Priya does not like Red and is not adjacent to Vikram. The person who likes Blue lives immediately below Rohan. Who lives on floor 4? Solution: Step 1: Rohan at floor 3, Blue lover immediately below → floor 2 = Blue Step 2: Green lover 3 floors from Sneha → possible pairs (1,4) or (2,5) Step 3: Priya not adjacent to Vikram, Priya not Red Step 4: Build grid and eliminate possibilities Step 5: Floor 4 occupant determined Answer: The person on floor 4 is determined by deduction
Pro Tips & Tricks
- Draw a vertical line with floor numbers from 1 (bottom) to N (top)
- Create a separate table mapping floors to persons and attributes
- 'Exactly k floors apart' means |floor(X) - floor(Y)| = k
- 'Immediately above' means consecutive floors with higher floor number
- Negative clues ('does not like') are as important as positive ones
- Use the process of elimination: if a floor can only have one person, assign it
