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 row 5, so no other queen can go in row 5. The Blue, Pink and Gray regions sit entirely in columns 4, 5 and 6, so no other queen can go in those columns. The Teal region has only one open square left, so its queen goes in row 6, column 7 (R6C7).
2. Step 2: The Red region has only one open square left, so its queen goes in row 4, column 3 (R4C3).
3. Step 3: The Orange region has only one open square left, so its queen goes in row 7, column 2 (R7C2).
4. Step 4: The Green region has only one open square left, so its queen goes in row 3, column 8 (R3C8).
5. Step 5: The Pink region has only one open square left, so its queen goes in row 5, column 5 (R5C5).
6. Step 6: The Blue region has only one open square left, so its queen goes in row 1, column 6 (R1C6).
7. Step 7: The Gray region has only one open square left, so its queen goes in row 9, column 4 (R9C4).
8. Step 8: The Purple region has only one open square left, so its queen goes in row 2, column 1 (R2C1).
9. Step 9: The Yellow region has only one open square left, so its queen goes in row 8, column 9 (R8C9).
