Queens #879 solution, step by step
Pick any step to see it on the board.
1. Queen on R1C9 Gray
Every open cell in row 1 is Gray. That line still needs a queen, so it must be the Gray queen, and the rest of the Gray region is out: R2C1, R2C5, R2C6, R2C8, R2C9, R3C1, R3C2, R3C8, R3C9, R4C1, R4C2, R4C9, R5C9, R6C9, R7C9, R8C9, R9C8 and R9C9.
Scan column 9: everything except R1C9 is already blocked, so the Gray region takes its queen there. After the usual cleanup (row 1, column 9, the touching squares and the rest of the color) 8 cells disappear.
2. Queen on R4C8 Green
Look along row 9: the only candidates left are Brown. Since the line needs a queen, Brown cells elsewhere (R5C7, R5C8, R6C1, R6C8, R7C1, R7C7, R7C8, R8C1, R8C2, R8C4, R8C5, R8C7 and R8C8) can be crossed out.
Column 8 has exactly one open square left, R4C8, and it belongs to the Green region. That is where the queen goes. That rules out 7 more cells across row 4, column 8, the rest of the color and the squares touching it.
3. Queen on R9C7 Brown
The Yellow region is boxed into row 3. That row belongs to it, so cross out R3C3.
A queen on R5C6 would wipe out the Teal region completely, which can never happen in a valid answer. Cross it off.
Inside the Orange region, R5C3 and R7C2 each attack every open cell of Blue and Red. Placing the queen on any of them would empty a region, so they are all eliminated.
Group Blue and Orange together: between them they fit inside rows 5 and 6 and nothing else. Those lines are spoken for, which knocks out R6C3, R6C5, R6C6 and R6C7.
Column 7 still needs a queen and R9C7 is the only candidate, which settles the Brown region as well. Crossing out its row, column, color and neighbours removes 7 candidates.
4. Queen on R7C6 Teal
The Teal region is down to one open cell, so its queen goes on R7C6. Crossing out its row, column, color and neighbours removes 4 candidates.
5. Queen on R8C3 Red
Only R8C3 is still free inside the Red region. The queen goes there. After the usual cleanup (row 8, column 3, the touching squares and the rest of the color) 1 cell disappears.
6. Queen on R5C1 Orange
Column 1 still needs a queen and R5C1 is the only candidate, which settles the Orange region as well. That rules out 4 more cells across row 5, column 1, the rest of the color and the squares touching it.
7. Queen on R6C4 Blue
Every other cell of the Blue region has been crossed out by now, which leaves R6C4 for its queen. That rules out 2 more cells across row 6, column 4, the rest of the color and the squares touching it.
8. Queen on R2C2 Purple
The Purple region is down to one open cell, so its queen goes on R2C2. Nothing new is crossed out, since its neighbours were already blocked.
9. Queen on R3C5 Yellow
Last one: the Yellow region gets its queen on R3C5, the one square nothing else attacks.
Done: R1C9, R2C2, R3C5, R4C8, R5C1, R6C4, R7C6, R8C3 and R9C7.
Region sizes
Yellow is the smallest region with 4 cells (queen on R3C5); Gray is the largest with 27 cells, and its queen sits on R1C9.

Solving Strategies
Pro tips to solve puzzles faster
Check Diagonals Carefully
Diagonal attacks are easy to miss. Always check all 8 surrounding cells when placing a queen to ensure no conflicts.
Work Row by Row
Focus on completing one row at a time. This systematic approach reduces mistakes and makes the puzzle more manageable.
Look for Isolated Regions

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.
