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 Orange region sits entirely in column 6, so no other queen can go in column 6. The Blue region sits entirely in column 8, so no other queen can go in column 8. The Teal region has only one open square left, so its queen goes in row 8, column 7 (R8C7).
2. Step 2: The Green region sits entirely in column 2, so no other queen can go in column 2. The Pink region has only one open square left, so its queen goes in row 7, column 3 (R7C3).
3. Step 3: The Red region has only one open square left, so its queen goes in row 6, column 1 (R6C1).
4. Step 4: The Green region has only one open square left, so its queen goes in row 4, column 2 (R4C2).
5. Step 5: The Yellow region has only one open square left, so its queen goes in row 5, column 4 (R5C4).
6. Step 6: Row 3 has only one open square left, so its queen goes in column 5 (Purple region) (R3C5).
7. Step 7: The Orange region has only one open square left, so its queen goes in row 1, column 6 (R1C6).
8. Step 8: The Blue region has only one open square left, so its queen goes in row 2, column 8 (R2C8).
