Basic Single Building: Direct Clues
Basic Single Building Floor Puzzles involve arranging a fixed number of people on different floors of a single building (typically floors 1 to N, where 1 is the lowest/bottom and N is the highest/top). You are given direct placement clues, immediate above/below relationships, simple comparative statements, and even/odd floor constraints. These foundational puzzles test your ability to translate verbal constraints into a complete vertical arrangement.

Introduction to Basic Single Building: Direct Clues
Basic Single Building Floor Puzzles involve arranging a fixed number of people on different floors of a single building (typically floors 1 to N, where 1 is the lowest/bottom and N is the highest/top). You are given direct placement clues, immediate above/below relationships, simple comparative statements, and even/odd floor constraints. These foundational puzzles test your ability to translate verbal constraints into a complete vertical arrangement.
Prerequisites
How to Solve Basic Single Building: Direct Clues Problems
Step 1: Identify the total number of floors (N) and the number of people
Step 2: Draw floors from 1 (bottom) to N (top) vertically
Step 3: Place all directly given people at their specified floors
Step 4: Apply 'immediately above/below' constraints to place consecutive people
Step 5: Apply simple 'above/below' constraints to establish relative ordering
Step 6: Use even/odd floor constraints to eliminate impossible floors
Step 7: Use process of elimination to fill remaining floors
Step 8: Verify that all clues are satisfied in the final arrangement
Example Problem
Example: 5 people A, B, C, D, E live on floors 1-5 (1=bottom). A lives on floor 3. B lives immediately above C. D lives on an even-numbered floor. E lives on the top floor. Find A's floor (given) and arrange others. Solution: Step 1: 5 floors: 1(bottom),2,3,4,5(top) Step 2: A at floor 3, E at floor 5 Step 3: B immediately above C → consecutive floors, B above C Step 4: D on even floor → could be 2 or 4 Step 5: Remaining floors: 1,2,4 for B,C,D Step 6: If D=4, then B,C must be 1,2 (consecutive with B above C → B=2,C=1) ✓ Step 7: Final: floor1=C, floor2=B, floor3=A, floor4=D, floor5=E Answer: Complete arrangement determined
Pro Tips & Tricks
- Floor 1 is lowest/bottom, Floor N is highest/top
- 'Immediately above' means floor difference = +1
- 'Immediately below' means floor difference = -1
- 'Lives above' (without 'immediately') means any higher floor
- Even-numbered floors: 2,4,6,8,...
- Odd-numbered floors: 1,3,5,7,9,...
