Multiple Buildings: Cross-Building Analysis
Multiple Buildings puzzles involve people distributed across two or more buildings, each with its own set of floors. Clues may compare floor numbers across buildings (e.g., 'X in Building A lives on the same floor number as Y in Building B') or provide building-specific constraints. These puzzles test coordination of multiple parallel arrangements.

Introduction to Multiple Buildings: Cross-Building Analysis
Multiple Buildings puzzles involve people distributed across two or more buildings, each with its own set of floors. Clues may compare floor numbers across buildings (e.g., 'X in Building A lives on the same floor number as Y in Building B') or provide building-specific constraints. These puzzles test coordination of multiple parallel arrangements.
Prerequisites
How to Solve Multiple Buildings: Cross-Building Analysis Problems
Step 1: Identify all buildings and their floor ranges
Step 2: Create separate grids/tables for each building
Step 3: Place directly assigned people in their buildings and floors
Step 4: Apply cross-building constraints (same floor number, different floor numbers)
Step 5: Apply intra-building constraints within each building
Step 6: Solve simultaneously, updating all buildings as you deduce
Step 7: Answer the specific question (e.g., which building and floor)
Example Problem
Example: Building A has floors 1-5, Building B has floors 1-5. X in Building A lives on floor 3. Y in Building B lives on the same floor number as X. Z in Building A lives immediately above W in Building A. Find Y's floor. Solution: Step 1: Building A floors 1-5, Building B floors 1-5 Step 2: X in A at floor 3 Step 3: Y in B at same floor as X → Y at floor 3 Step 4: Z immediately above W in A Step 5: Y at floor 3 Answer: Y on floor 3 in Building B
Pro Tips & Tricks
- Draw each building as a separate column
- Same floor number across buildings links positions at the same vertical level
- Different floor numbers indicate inequality constraints across buildings
- Each building has its own set of floors (may have different ranges)
- The same person cannot be in two buildings
- Use building names in clues to identify which building is referenced
