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 has only one open square left, so its queen goes in row 8, column 1 (R8C1).
2. Step 2: The Pink region has only one open square left, so its queen goes in row 7, column 3 (R7C3).
3. Step 3: The Orange region has only one open square left, so its queen goes in row 5, column 2 (R5C2).
4. Step 4: The Purple region has only one open square left, so its queen goes in row 6, column 5 (R6C5).
5. Step 5: The Blue region sits entirely in column 4, so no other queen can go in column 4. The Red region sits entirely in row 4, so no other queen can go in row 4. The Blue region has only one open square left, so its queen goes in row 3, column 4 (R3C4).
6. Step 6: The Teal region sits entirely in row 2, so no other queen can go in row 2. Column 8 has only one open square left, so its queen goes in row 1 (Yellow region) (R1C8).
7. Step 7: The Teal region has only one open square left, so its queen goes in row 2, column 6 (R2C6).
8. Step 8: The Red region has only one open square left, so its queen goes in row 4, column 7 (R4C7).
