How to Solve Queens-Style Puzzles Without Guessing: The Complete Star Battle Strategy Guide
If you got hooked on the LinkedIn Queens game and want more boards, harder sizes, or just to stop guessing — this guide is for you. Queens-style puzzles (a one-star variant of the classic Star Battle) are 100% solvable by logic. Below are the five techniques that crack every board, from beginner 5×5 up to expert 11×11.
Technique 1 — Singles: play the forced moves first
If a region has only one cell, that cell is a diamond. If a row or column has only one non-excluded cell left, same thing. Every solve starts by sweeping for these freebies, and every diamond you place creates an exclusion halo: its whole row, whole column, and all 8 neighbors become dead cells. Mark them (✕ in the game) before hunting the next move.
Technique 2 — Region confinement: when a color locks a row
If all remaining cells of a color region sit in a single row, that region's diamond must be in that row — so every other cell of that row is dead, even outside the region. The same works for columns. This is the most powerful technique in the game and the engine behind most "aha" moments. Watch L-shaped and bar-shaped regions: they confine early and often.
Technique 3 — Exclusion zones: the diagonal squeeze
Because diamonds can't touch, a two-cell region always kills any cell that neighbors both of its cells. More generally: take a region, imagine every placement it could still use, and intersect the exclusion halos — any outside cell touched by all possible placements is dead. Small regions squeezed into corners generate huge dead zones this way.
Technique 4 — Counting: N regions need N rows
If three color regions live entirely inside three rows, those rows' diamonds must all come from those regions — so any other region's cells inside those rows are dead. This pigeonhole argument also works with columns, and it's what separates intermediate from expert solvers. On 10×10 and 11×11 boards, counting is usually the key that unlocks the middle game.
Technique 5 — Hypothetical elimination: test, don't guess
Stuck? Pick a candidate cell and mentally play it. If within two or three forced moves you hit a contradiction — a region with no cells left, two diamonds forced to touch — the candidate is dead: mark ✕ and move on. This isn't guessing: you never commit, you only disprove. Experts run these micro-simulations constantly.
A worked micro-example
Suppose region 🟦 has no cells outside rows 1–2, and region 🟥 is also confined to rows 1–2:
🟥🟥🟦🟦🟦
🟥🟥🟩🟦🟦
By counting, rows 1 and 2 must be claimed by 🟥 and 🟦 — so 🟩's cell in row 2 is dead immediately, before a single diamond is placed.
From 5×5 warm-ups to 11×11 marathons
Board size changes which technique dominates. On 5×5–7×7, singles and confinement carry you. On 8×8–9×9, exclusion zones start to matter. On 10×10 and 11×11 — sizes the LinkedIn game never reaches — you'll need counting and hypothetical elimination on almost every solve. That difficulty ramp is exactly what 11 Diamond's story mode teaches, one board size at a time.

FAQ
Is this the same as the LinkedIn Queens game?
Same rule set (one marker, no touching), more sizes, unlimited boards, and a competitive layer. Queens itself is a one-star Star Battle variant.
Are the puzzles guaranteed solvable?
Yes — every board is machine-verified to have exactly one solution reachable by the techniques above, never guessing.
Does it cost anything?
No. The game, daily challenge and contest entry are all free.
