Queens #821 solution, step by step

Pick any step to see it on the board.

  1. 1. Queen on R4C3 Green

    1. The open squares of columns 1 and 2 all belong to Purple and Orange. Both queens of those colors are therefore used up here, which removes R1C3, R1C4, R1C5, R1C6, R1C7, R1C8, R1C9, R2C3, R2C4, R2C5, R2C6, R2C9, R3C3, R3C9, R4C8, R4C9, R5C3, R5C8, R5C9, R6C3, R6C4, R6C8, R6C9, R7C3, R7C4, R7C5, R7C7, R7C9, R8C3, R8C5, R8C6, R8C7, R9C3, R9C6, R9C7, R9C8 and R9C9.

    2. Column 3 has exactly one open square left, R4C3, and it belongs to the Green region. That is where the queen goes. That rules out 10 more cells across row 4, column 3, the rest of the color and the squares touching it.

  2. 2. Queen on R8C9 Brown

    1. Scan column 9: everything except R8C9 is already blocked, so the Brown region takes its queen there. Crossing out its row, column, color and neighbours removes 5 candidates.

  3. 3. Queen on R9C4 Teal

    1. Column 4 still needs a queen and R9C4 is the only candidate, which settles the Teal region as well. After the usual cleanup (row 9, column 4, the touching squares and the rest of the color) 3 cells disappear.

  4. 4. Queen on R1C1 Purple

    1. Every open cell in column 8 is Blue. That line still needs a queen, so it must be the Blue queen, and the rest of the Blue region is out: R2C7.

    2. The Orange region cannot use R1C2 and R3C1: each of those squares leaves Purple with nowhere to go.

    3. Row 1 still needs a queen and R1C1 is the only candidate, which settles the Purple region as well. Crossing out its row, column, color and neighbours removes 5 candidates.

  5. 5. Queen on R2C8 Blue

    1. Row 2 has exactly one open square left, R2C8, and it belongs to the Blue region. That is where the queen goes. After the usual cleanup (row 2, column 8, the touching squares and the rest of the color) 2 cells disappear.

  6. 6. Queen on R6C7 Yellow

    1. Row 3 can only be filled by the Gray region. That pins the Gray queen to this line and removes R5C7.

    2. Column 7 still needs a queen and R6C7 is the only candidate, which settles the Yellow region as well. That rules out 5 more cells across row 6, column 7, the rest of the color and the squares touching it.

  7. 7. Queen on R7C2 Orange

    1. Every other cell of the Orange region has been crossed out by now, which leaves R7C2 for its queen. Nothing new is crossed out, since its neighbours were already blocked.

  8. 8. Queen on R5C5 Red

    1. The Red region is down to one open cell, so its queen goes on R5C5. Crossing out its row, column, color and neighbours removes 1 candidate.

  9. 9. Queen on R3C6 Gray

    1. Last one: the Gray region gets its queen on R3C6, the one square nothing else attacks.

In row order the same answer reads R1C1, R2C8, R3C6, R4C3, R5C5, R6C7, R7C2, R8C9 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.
