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 3, so no other queen can go in row 3. The Teal region sits entirely in row 7, so no other queen can go in row 7. The Blue, Yellow and Pink regions sit entirely in rows 4, 5 and 6, so no other queen can go in those rows. The Orange region sits entirely in row 2, so no other queen can go in row 2. The Orange, Green and Yellow regions sit entirely in columns 5, 6 and 7, so no other queen can go in those columns. The Blue and Teal regions sit entirely in columns 3 and 4, so no other queen can go in those columns. The Pink region has only one open square left, so its queen goes in row 6, column 2 (R6C2).
2. Step 2: The Teal region has only one open square left, so its queen goes in row 7, column 4 (R7C4).
3. Step 3: The Blue region has only one open square left, so its queen goes in row 4, column 3 (R4C3).
4. Step 4: Column 7 has only one open square left, so its queen goes in row 2 (Orange region) (R2C7).
5. Step 5: The Purple region has only one open square left, so its queen goes in row 1, column 1 (R1C1).
6. Step 6: The Green region has only one open square left, so its queen goes in row 3, column 5 (R3C5).
7. Step 7: The Yellow region has only one open square left, so its queen goes in row 5, column 6 (R5C6).
8. Step 8: The Red region has only one open square left, so its queen goes in row 8, column 8 (R8C8).
