About

Queens Puzzle is a logic game with one rule set and a wonderfully unforgiving constraint: fill the board so that every row, every column, and every colored region contains exactly one crown — and no two crowns may touch, not even diagonally. There's no arithmetic and no guessing needed, only the steady elimination of what can't be true until only one answer remains.

The colored regions are what make this harder than a straightforward row-and-column puzzle. A region might be a single oddly shaped blob spanning two corners of the board, forcing you to satisfy its one-crown requirement while simultaneously respecting the rows and columns that cut through it. Marking cells with an ✕ as you rule them out — rather than committing crowns immediately — is what makes the deduction visible and reversible.

Every puzzle is generated with exactly one valid solution, and boards scale from a gentle 6×6 up to a demanding 10×10, with a fresh daily challenge resetting at midnight alongside unlimited practice puzzles. It's a clean, no-login logic break that rewards patient scanning over trial and error.

How to Play

• Tap a cell once to mark it with an ✕ (no crown allowed), tap again to place a crown, and a third tap clears it.
• On desktop, drag to paint ✕ marks across cells and right-click to place a crown directly.
• Place exactly one crown in every row, every column, and every colored region.
• No two crowns can touch each other, including diagonally adjacent cells.
• Enable Auto-✕ to automatically eliminate the surrounding cells whenever you place a crown.

Tips

• Start with color regions that only span a couple of cells — they narrow down fastest and cascade into other deductions.
• Use the ✕ mark liberally before committing to a crown; visible eliminations make contradictions obvious sooner.
• When a row or column has only one region-consistent cell left, its crown is forced — look for these single-candidate squares first.

History

Queens Puzzle belongs to the Star Battle family of pencil puzzles, adapted here into a single-crown-per-region variant that shares its core ruleset with LinkedIn's popular "Queens" game, though this site is an independent, unaffiliated implementation. The constraint-satisfaction genre it draws from — one item per row, column, and region, with an adjacency restriction — has circulated in puzzle magazines for decades under various names before being popularized to a mass daily audience by the recent wave of browser logic games following Wordle's success.
