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 Pink region sits entirely in column 1, so no other queen can go in column 1. The Red region sits entirely in row 9, so no other queen can go in row 9. The Purple and Red regions sit entirely in columns 2 and 3, so no other queen can go in those columns. The Orange region sits entirely in row 4, so no other queen can go in row 4. The Gray region sits entirely in column 4, so no other queen can go in column 4. The Orange region has only one open square left, so its queen goes in row 4, column 5 (R4C5).
2. Step 2: The Green region has only one open square left, so its queen goes in row 2, column 6 (R2C6).
3. Step 3: The Purple region sits entirely in row 1, so no other queen can go in row 1. 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 7, column 7 (R7C7).
4. Step 4: The Gray region has only one open square left, so its queen goes in row 8, column 4 (R8C4).
5. Step 5: The Red region has only one open square left, so its queen goes in row 9, column 2 (R9C2).
6. Step 6: The Purple region has only one open square left, so its queen goes in row 1, column 3 (R1C3).
7. Step 7: Row 6 has only one open square left, so its queen goes in column 9 (Yellow region) (R6C9).
8. Step 8: The Blue region has only one open square left, so its queen goes in row 3, column 8 (R3C8).
9. Step 9: The Pink region has only one open square left, so its queen goes in row 5, column 1 (R5C1).
