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 Red, Pink and Gray regions sit entirely in columns 6, 7 and 8, so no other queen can go in those columns. The Orange, Green and Teal regions sit entirely in columns 3, 4 and 5, so no other queen can go in those columns. The Purple region sits entirely in row 1, so no other queen can go in row 1. Column 6 has only one open square left, so its queen goes in row 8 (Gray region) (R8C6).
2. Step 2: The Green region has only one open square left, so its queen goes in row 7, column 4 (R7C4).
3. Step 3: Column 3 has only one open square left, so its queen goes in row 3 (Orange region) (R3C3).
4. Step 4: The Pink region has only one open square left, so its queen goes in row 2, column 7 (R2C7).
5. Step 5: The Teal region has only one open square left, so its queen goes in row 4, column 5 (R4C5).
6. Step 6: The Red region has only one open square left, so its queen goes in row 5, column 8 (R5C8).
7. Step 7: The Blue region has only one open square left, so its queen goes in row 6, column 2 (R6C2).
8. Step 8: The Purple region has only one open square left, so its queen goes in row 1, column 1 (R1C1).
9. Step 9: The Yellow region has only one open square left, so its queen goes in row 9, column 9 (R9C9).
