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, Green, Red and Gray regions sit entirely in columns 1, 2, 3, 4 and 5, 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 6 (R5C6).
2. Step 2: The Blue region has only one open square left, so its queen goes in row 3, column 7 (R3C7).
3. Step 3: The Green region sits entirely in row 4, so no other queen can go in row 4. The Purple and Orange regions sit entirely in rows 1 and 2, so no other queen can go in those rows. The Pink region has only one open square left, so its queen goes in row 6, column 8 (R6C8).
4. Step 4: The Red region has only one open square left, so its queen goes in row 7, column 2 (R7C2).
5. Step 5: The Gray region has only one open square left, so its queen goes in row 8, column 4 (R8C4).
6. Step 6: The Green region has only one open square left, so its queen goes in row 4, column 3 (R4C3).
7. Step 7: The Purple region has only one open square left, so its queen goes in row 2, column 5 (R2C5).
8. Step 8: The Orange region has only one open square left, so its queen goes in row 1, column 1 (R1C1).
9. Step 9: The Teal region has only one open square left, so its queen goes in row 9, column 9 (R9C9).
