Solution coordinates

Rows are counted from the top and columns from the left, so R1C1 is the top-left square. Small numbers show the order the queens are found.

Queens #851 solution, step by step

Pick any step to see it on the board.

  1. 1. Queen on R3C3 Orange

    1. Notice that the Orange region only has candidates in row 3. Any other color in that line can be removed, which clears R3C1, R3C2, R3C8 and R3C9.

    2. Purple and Red are confined to rows 1 and 2. Two colors packed into two rows use up every queen those lines can hold, so the stray cells of other colors go: R1C1, R1C2, R1C3, R1C4, R1C8, R1C9, R2C1, R2C2, R2C3 and R2C9.

    3. The open squares of columns 1 and 2 all belong to Blue and Green. Both queens of those colors are therefore used up here, which removes R4C3, R5C3, R5C4, R6C3, R6C4, R7C3, R7C4, R8C3, R8C4 and R9C3.

    4. Column 3 still needs a queen and R3C3 is the only candidate, which settles the Orange region as well. That rules out 7 more cells across row 3, column 3, the rest of the color and the squares touching it.

  2. 2. Queen on R9C4 Brown

    1. Column 4 has exactly one open square left, R9C4, and it belongs to the Brown region. That is where the queen goes. Crossing out its row, column, color and neighbours removes 9 candidates.

  3. 3. Queen on R4C6 Gray

    1. The Blue region is boxed into column 1. That column belongs to it, so cross out R6C1, R7C1 and R8C1.

    2. Counting argument: two regions (Purple and Gray) live entirely in two columns (columns 5 and 6). No other color can place a queen there, so remove R1C6, R5C6, R6C6, R7C6 and R8C6.

    3. Test R2C6 in the Purple region: a queen there would attack every remaining Red cell. Red would be left empty, so R2C6 is out.

    4. Scan column 6: everything except R4C6 is already blocked, so the Gray region takes its queen there. Crossing out its row, column, color and neighbours removes 8 candidates.

  4. 4. Queen on R5C1 Blue

    1. The Blue region is down to one open cell, so its queen goes on R5C1. Crossing out its row, column, color and neighbours removes 4 candidates.

  5. 5. Queen on R8C7 Yellow

    1. Only R8C7 is still free inside the Yellow region. The queen goes there. After the usual cleanup (row 8, column 7, the touching squares and the rest of the color) 8 cells disappear.

  6. 6. Queen on R2C8 Red

    1. The Red region has nowhere else to go: R2C8 is its last legal square. 2 cells drop out once you mark the row, column and the eight surrounding squares.

  7. 7. Queen on R1C5 Purple

    1. Every other cell of the Purple region has been crossed out by now, which leaves R1C5 for its queen. Nothing new is crossed out, since its neighbours were already blocked.

  8. 8. Queen on R7C2 Green

    1. The Green region is down to one open cell, so its queen goes on R7C2. Crossing out its row, column, color and neighbours removes 1 candidate.

  9. 9. Queen on R6C9 Teal

    1. Last one: the Teal region gets its queen on R6C9, the one square nothing else attacks.

Result for #851: R1C5, R2C8, R3C3, R4C6, R5C1, R6C9, R7C2, R8C7 and R9C4.

Game Rules

Master these rules to solve any Queens puzzle

  • One Queen Per Color

    Each colored region must contain exactly one queen.

  • No Attacks

    Queens cannot attack each other horizontally, vertically, or diagonally.

  • No Adjacent Queens

    Queens cannot touch each other, even diagonally.

Solving Strategies

Pro tips to solve puzzles faster

  • Look for Isolated Regions

    Regions that are separated from others often have unique solutions. Identify them early to gain an advantage.

  • Start with Corners

    Look at corner regions first. They often have limited placement options, making them easier to solve and providing a good starting point.

  • Mark Conflicts

    Use X marks to indicate where queens cannot be placed due to row, column, or diagonal conflicts. This visual aid helps narrow down options.

  • Process of Elimination

    If a color region has only one available cell after considering all conflicts, place the queen there with confidence.
