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 Orange and Pink regions sit entirely in columns 4 and 5, so no other queen can go in those columns. The Green region sits entirely in column 6, so no other queen can go in column 6. The Purple region sits entirely in column 7, so no other queen can go in column 7. The Blue and Green regions sit entirely in rows 3 and 4, so no other queen can go in those rows. The Purple region has only one open square left, so its queen goes in row 5, column 7 (R5C7).
2. Step 2: The Green region has only one open square left, so its queen goes in row 3, column 6 (R3C6).
3. Step 3: The Orange region has only one open square left, so its queen goes in row 2, column 4 (R2C4).
4. Step 4: The Red region has only one open square left, so its queen goes in row 6, column 3 (R6C3).
5. Step 5: The Blue region has only one open square left, so its queen goes in row 4, column 2 (R4C2).
6. Step 6: The Pink region has only one open square left, so its queen goes in row 7, column 5 (R7C5).
7. Step 7: The Teal region has only one open square left, so its queen goes in row 8, column 1 (R8C1).
8. Step 8: The Yellow region has only one open square left, so its queen goes in row 1, column 8 (R1C8).
