Queens #815 solution, step by step

Pick any step to see it on the board.

  1. 1. Queen on R6C7 Brown

    1. Notice that the Yellow region only has candidates in row 5. Any other color in that line can be removed, which clears R5C1, R5C2, R5C3, R5C7, R5C8 and R5C9.

    2. Every open cell in column 1 is Purple. That line still needs a queen, so it must be the Purple queen, and the rest of the Purple region is out: R1C2, R2C2, R8C2 and R9C2.

    3. Column 2 can only be filled by the Orange region. That pins the Orange queen to this line and removes R1C3, R1C4, R2C3, R2C4, R3C3, R7C3, R8C3, R8C4 and R9C3.

    4. Look along column 3: the only candidates left are Red. Since the line needs a queen, Red cells elsewhere (R4C4, R4C5, R4C6, R4C7, R6C4 and R7C4) can be crossed out.

    5. Every open cell in column 9 is Gray. That line still needs a queen, so it must be the Gray queen, and the rest of the Gray region is out: R1C8, R2C8, R8C8 and R9C8.

    6. Column 8 can only be filled by the Green region. That pins the Green queen to this line and removes R1C7, R2C6, R2C7, R3C6, R3C7, R7C7, R8C7 and R9C7.

    7. Column 7 still needs a queen and R6C7 is the only candidate, which settles the Brown region as well. 12 cells drop out once you mark the row, column and the eight surrounding squares.

  2. 2. Queen on R4C3 Red

    1. The Red region has nowhere else to go: R4C3 is its last legal square. 7 cells drop out once you mark the row, column and the eight surrounding squares.

  3. 3. Queen on R7C2 Orange

    1. Every other cell of the Orange region has been crossed out by now, which leaves R7C2 for its queen. That rules out 3 more cells across row 7, column 2, the rest of the color and the squares touching it.

  4. 4. Queen on R3C8 Green

    1. The Green region is down to one open cell, so its queen goes on R3C8. Crossing out its row, column, color and neighbours removes 4 candidates.

  5. 5. Queen on R5C5 Yellow

    1. Only R5C5 is still free inside the Yellow region. The queen goes there. After the usual cleanup (row 5, column 5, the touching squares and the rest of the color) 3 cells disappear.

  6. 6. Queen on R1C6 Blue

    1. The Blue region has nowhere else to go: R1C6 is its last legal square. 4 cells drop out once you mark the row, column and the eight surrounding squares.

  7. 7. Queen on R9C4 Teal

    1. Every other cell of the Teal region has been crossed out by now, which leaves R9C4 for its queen. That rules out 2 more cells across row 9, column 4, the rest of the color and the squares touching it.

  8. 8. Queen on R2C1 Purple

    1. The Purple region is down to one open cell, so its queen goes on R2C1. Nothing new is crossed out, since its neighbours were already blocked.

  9. 9. Queen on R8C9 Gray

    1. Last one: the Gray region gets its queen on R8C9, the one square nothing else attacks.

Result for #815: R1C6, R2C1, R3C8, 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.
