Queens solution, step by step

Each LinkedIn Queens step places one queen and closes its row, its column, its region and the squares touching it.

1. Step 1: The Green region sits entirely in row 1, so no other queen can go in row 1. The Orange and Blue regions sit entirely in rows 2 and 3, so no other queen can go in those rows. The Teal region has only one open square left, so its queen goes in row 4, column 9 (R4C9).
2. Step 2: The Green region has only one open square left, so its queen goes in row 1, column 8 (R1C8).
3. Step 3: The Yellow region has only one open square left, so its queen goes in row 5, column 4 (R5C4).
4. Step 4: The Orange and Red regions sit entirely in columns 2 and 3, so no other queen can go in those columns. The Blue and Pink regions sit entirely in columns 6 and 7, so no other queen can go in those columns. The Gray region has only one open square left, so its queen goes in row 9, column 5 (R9C5).
5. Step 5: A queen in row 7, column 2 would leave the Purple region with no open square, so that square is out. Column 2 has only one open square left, so its queen goes in row 2 (Orange region) (R2C2).
6. Step 6: The Blue region has only one open square left, so its queen goes in row 3, column 7 (R3C7).
7. Step 7: The Pink region has only one open square left, so its queen goes in row 7, column 6 (R7C6).
8. Step 8: The Red region has only one open square left, so its queen goes in row 8, column 3 (R8C3).
9. Step 9: The Purple region has only one open square left, so its queen goes in row 6, column 1 (R6C1).
