LinkedIn Queens
Place one queen per row, column, and colour region. No two queens may touch — not even diagonally.
About LinkedIn Queens
LinkedIn Queens is a logic puzzle from LinkedIn's daily games lineup. You're given an N×N board partitioned into N coloured regions, and you must place exactly one queen per row, per column, and per region — with no two queens touching, not even diagonally. There is exactly one valid placement per puzzle.
On Ludingo we ship 200 easy 7×7, 200 medium 8×8, and 10 hard 9×9 hand-curated puzzles — no daily limit, no LinkedIn account needed, no install. Every puzzle is uniquely numbered so you can share a link and race the same puzzle with friends.
How to play
- Place exactly one queen per row.
- Place exactly one queen per column.
- Place exactly one queen per coloured region.
- No two queens may be adjacent — not even diagonally. Use X marks to track cells you've ruled out.
How to solve Queens — strategy and techniques
Start with the smallest coloured region. A region of one or two cells barely has options — a single-cell region IS a queen, and you can immediately cross out its entire row, column and the surrounding cells.
Use X marks aggressively. Every placed queen eliminates its row, its column and all eight surrounding cells. Marking those eliminations by hand feels slow but is exactly what reveals the next forced placement — most players stall because they try to keep the picture in their head.
Look for line monopolies: when all of a region’s remaining cells fall inside one row or column, that region’s queen will occupy the line — so every other region’s cells in the same line can be crossed out before you even know the queen’s exact position.
Chase forced moves to the very end before trying anything speculative. Every Ludingo Queens puzzle has a single solution, so a correct chain of eliminations always produces another forced queen; if you feel you must guess, an elimination was missed somewhere.
Tips for faster solves
- Single-cell regions are free queens — place them first and cross out around them.
- After every queen, X its row, column and all neighbouring cells before moving on.
- A region trapped in one row or column claims that line — cross it out for everyone else.
- On hard 9×9 boards start from the corners: cornered regions have the fewest options.
Questions about LinkedIn Queens
What are the LinkedIn Queens rules?
Place one queen in each row, column, and coloured region of the board, and ensure no two queens are touching — orthogonally or diagonally. The colour regions are the unique twist that turns a generic n-queens problem into a single-solution puzzle.
Is this the same Queens game as LinkedIn's?
Same rules, different board generation. Each Ludingo puzzle is generated and uniqueness-checked by our own engine so you can play unlimited times without a LinkedIn account or daily reset.
Do I need a LinkedIn account?
No. Ludingo Queens runs entirely in your browser — no login required for casual play. Signing in only enables persistent stats and cross-device sync.
How does the puzzle numbering work?
Every puzzle has a stable ID like `easy_42` or `hard_3` that's the same on every device. Share the URL with a friend and they'll get the exact same board — perfect for racing the time.
What is the fastest way to get better at Queens?
Play the easy 7×7 pool until the eliminations feel automatic, then move up. Speed comes from recognising the recurring patterns — single-cell regions, line monopolies and touch conflicts — not from clicking faster.
Can I play Queens on mobile?
Yes — the board works in any mobile browser with tap-to-cycle input (empty → X → queen). No app or account is required, and your current puzzle is saved locally.
