Comparison
LinkedIn Queens vs Coronet
LinkedIn Queens is the crown-placement puzzle in LinkedIn's Games tab. Coronet is an independent daily built on the same ruleset, free in any browser with no LinkedIn account required.
What's the same
Both are colour-region queens puzzles: a grid split into coloured regions, exactly one crown per row, column, and region, and no two crowns touching — not even diagonally. Every board has a single solution reachable by deduction, so neither wants you to guess.
How Coronet differs
LinkedIn gives you one board a day inside the app. Coronet adds a 60-day archive to replay past boards and unlimited practice from 5×5 up to 12×12, so you are not done after one grid. It runs in any browser without a login and sits inside a nine-game arcade.
Verdict
If you like LinkedIn Queens, Coronet is the same puzzle with an archive, bigger practice boards, and nothing to sign into.
