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 Purple, Orange, Blue, Green, Gray, Red, Yellow and Beige regions sit entirely in rows 2, 3, 4, 5, 6, 7, 8 and 9, so no other queen can go in those rows. A queen in row 2, column 8 would leave column 9 with no open square, so that square is out. A queen in row 4, column 6 would leave the Orange region with no open square, so that square is out. The Blue, Green, Gray, Red and Yellow regions sit entirely in rows 5, 6, 7, 8 and 9, so no other queen can go in those rows. Column 9 has only one open square left, so its queen goes in row 1 (Pink region) (R1C9).
2. Step 2: The Purple, Orange, Blue, Red, Yellow and Beige regions sit entirely in columns 3, 4, 5, 6, 7 and 8, so no other queen can go in those columns. The Gray region sits entirely in column 2, so no other queen can go in column 2. The Green, Gray and Red regions sit entirely in rows 7, 8 and 9, so no other queen can go in those rows. The Yellow region sits entirely in row 6, so no other queen can go in row 6. The Purple, Orange, Red and Yellow regions sit entirely in columns 3, 4, 5 and 6, so no other queen can go in those columns. The Blue region has only one open square left, so its queen goes in row 5, column 7 (R5C7).
3. Step 3: The Yellow region has only one open square left, so its queen goes in row 6, column 5 (R6C5).
4. Step 4: The Beige region has only one open square left, so its queen goes in row 3, column 8 (R3C8).
5. Step 5: Row 7 has only one open square left, so its queen goes in column 1 (Green region) (R7C1).
6. Step 6: The Gray region has only one open square left, so its queen goes in row 9, column 2 (R9C2).
7. Step 7: The Red region has only one open square left, so its queen goes in row 8, column 4 (R8C4).
8. Step 8: The Purple region has only one open square left, so its queen goes in row 4, column 3 (R4C3).
9. Step 9: The Orange region has only one open square left, so its queen goes in row 2, column 6 (R2C6).
