Introduction to Box Puzzle (Color-City-Item-Floor)
Complex Box Puzzles involve arranging boxes with multiple attributes: color, city, item, and floor (position in stack). Each attribute has unique values across boxes. These puzzles require systematic elimination and multi-dimensional reasoning.
Prerequisites
How to Solve Box Puzzle (Color-City-Item-Floor) Problems
Step 1: Create a table with floors as rows and attributes as columns
Step 2: Place direct assignments (e.g., 'Top floor box is Red')
Step 3: Apply floor gap constraints (e.g., 'exactly k boxes between')
Step 4: Apply adjacency constraints (e.g., 'immediately above/below')
Step 5: Apply even/odd floor constraints
Step 6: Use attribute matching clues (e.g., 'Red box is from Delhi')
Step 7: Use elimination to complete the table
Step 8: Answer questions about specific attributes
Example Problem
Example: Seven boxes with colors, cities, items on 7 floors. Top floor box is Red. Bottom floor box is from Pune. Exactly 2 boxes between Red box and Blue box. Green box immediately below Orange box. Box from Delhi on even floor. Box containing Laptop not at top or bottom. Find color of box on floor 3. Solution: Step 1: Create 7x4 table (Floor, Color, City, Item) Step 2: Place Red at floor 7, Pune at floor 1 Step 3: 2 boxes between Red and Blue → Blue at floor 4 (since 7-4=3, boxes between = 2) Step 4: Green immediately below Orange → consecutive floors Step 5: Delhi on even floor (2,4,6) Step 6: Laptop not at floor 1 or 7 Step 7: Use elimination to complete Answer: Color of box at floor 3 identified
Pro Tips & Tricks
- Floors: N (top) to 1 (bottom) or 1 (bottom) to N (top) - read carefully
- Each attribute (color, city, item) has unique values across boxes
- Use a table with floors as rows, attributes as columns
- Start with definite floor assignments
- Use gap constraints to calculate possible floor positions
- Even/odd constraints eliminate half the floors
