How to enter your board
- Pick the size. Count the squares along one side of your puzzle. LinkedIn’s Queens is usually 7 to 11 across.
- Choose a color and tap or drag over every square of one region. Then pick the next color for the next region. The colors don’t have to match your puzzle’s, only the shapes do.
- Keep going until every square is painted. The counter under the board tells you how many regions you have and how many squares are left. If a color ends up in two separate pieces, it says so: Queens regions are always joined.
- Press Solve. You can paint over a square at any time to fix it, and your board is kept on this device if you switch tabs.
On a keyboard, the arrow keys move between squares, space paints, backspace erases and the number keys pick a color.
Why it shows steps, not just the answer
A fair Queens puzzle has exactly one answer, and you can reach it by reasoning alone: a region that fits inside one row, a square that would leave a column with nowhere to go. The answer tells you where the queens are. The steps tell you why, and that is what gets you through tomorrow’s puzzle without help.
So the solver checks your board twice. First an exact solver counts every possible arrangement, to make sure there is one and only one. Then a second solver uses only the moves a person would make, and names each one. Every technique links to its lesson in How to solve Queens. Some very hard boards need a supposition the step solver can’t phrase as a single move; when that happens, it says so plainly and shows the answer. How we check every puzzle explains the same two solvers behind our daily puzzles.
Works with LinkedIn’s Queens
LinkedIn’s Queens uses the same rules as ours: one queen in every row, every column and every colored region, and no two queens touching, not even at a corner. So any board from its daily game can be painted here and solved. The same goes for Queens boards from apps, books and newspapers, and for one-star Star Battle puzzles, which are the same puzzle under another name.
Logic Puzzle Club is not affiliated with LinkedIn. We make our own Queens puzzles: today’s Queens is new every day, and unlimited Queens gives you a fresh board whenever you want one.
Questions
Is this solver free?
Yes. It runs in your browser, needs no account and sends your board nowhere.
Why does it say my board has more than one answer?
A real Queens puzzle has exactly one answer, so two or more almost always means a square was painted the wrong color. Compare the region shapes with your puzzle, square by square, and solve again.
Why does it say no arrangement works?
Every placement of queens broke a rule, which also points to a painting slip. A region that is one square too big or too small can be enough.
Can I get a hint without seeing the whole answer?
Yes. Press Show the first step and stop when you’ve seen enough. Each step highlights the squares it uses and explains the move, and the queens only appear as the steps place them.
Does Queens ever need guessing?
No. A fair Queens puzzle can always be finished by reasoning. The hardest moves are suppositions: imagine a queen on a square, follow what it forces, and see it break a rule. That is proof by contradiction, not a guess. Our lesson Deduce, don’t guess explains the difference.
