How to Solve LinkedIn Queens Puzzle: Complete Strategy Guide

Understanding LinkedIn Queens Rules

LinkedIn Queens is a modern twist on the classic N-Queens problem. The board is divided into 4-6 colored regions. Your task: place exactly one queen per colored region such that:

• No two queens share the same row or column
• No two queens are adjacent (including diagonals)
• One queen per colored region

The adjacency rule (queens cannot touch, even diagonally) makes Queens significantly harder than standard chess queens placement.

Strategy 1: Identify Forced Placements (Most Important)

Start with regions that have only one possible position. Look for:

• Corner regions: Can only place in 1-2 specific cells
• Regions reduced to 1 cell after eliminating shared rows/columns
• Regions where only one cell avoids adjacency with other forced queens

Pro Tip: Place ALL forced queens first. Each placement eliminates entire rows, columns, and adjacent cells.

Strategy 2: The Elimination Grid Method

Mentally (or on paper) mark cells as "impossible" based on:

After marking eliminations, many regions reduce to 1-2 possible cells.

Strategy 3: The Balance Rule

Count available rows and columns remaining. If you have 3 regions left but only 2 rows available in their area, you know there's a conflict somewhere.

Advanced: Backtracking Tree

For 5+ region puzzles, build a decision tree:

1. Place all forced queens
2. Choose region with fewest options (2-3 cells)
3. Test each option, propagate eliminations
4. Dead end? Backtrack to previous choice

Common Mistakes & How to Avoid Them

• Overlooking adjacency: Queens cannot touch diagonally either
• Rush placement: Always check if new queen conflicts with ALL existing
• Forgetting regions: Double-check each region has exactly one queen
