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 Blue region sits entirely in row 1, so no other queen can go in row 1. The Orange, Green and Teal regions sit entirely in rows 2, 3 and 4, so no other queen can go in those rows. The Yellow region sits entirely in row 5, so no other queen can go in row 5. The Red and Pink regions sit entirely in rows 6 and 7, so no other queen can go in those rows. Column 1 has only one open square left, so its queen goes in row 8 (Purple region) (R8C1).
2. Step 2: The Blue, Green and Pink regions sit entirely in columns 5, 6 and 7, so no other queen can go in those columns. The Yellow region has only one open square left, so its queen goes in row 5, column 4 (R5C4).
3. Step 3: A queen in row 2, column 6 would leave the Blue region with no open square, so that square is out. A queen in row 3, column 7 would leave the Teal region with no open square, so that square is out. Column 7 has only one open square left, so its queen goes in row 6 (Pink region) (R6C7).
4. Step 4: The Red region has only one open square left, so its queen goes in row 7, column 3 (R7C3).
5. Step 5: The Orange region has only one open square left, so its queen goes in row 3, column 2 (R3C2).
6. Step 6: The Green region has only one open square left, so its queen goes in row 4, column 6 (R4C6).
7. Step 7: The Blue region has only one open square left, so its queen goes in row 1, column 5 (R1C5).
8. Step 8: The Teal region has only one open square left, so its queen goes in row 2, column 8 (R2C8).
