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 Green and Red regions sit entirely in rows 7 and 8, 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 Green and Yellow regions sit entirely in columns 7 and 8, so no other queen can go in those columns. The Pink region has only one open square left, so its queen goes in row 5, column 6 (R5C6).
2. Step 2: The Yellow region has only one open square left, so its queen goes in row 6, column 8 (R6C8).
3. Step 3: The Green region has only one open square left, so its queen goes in row 8, column 7 (R8C7).
4. Step 4: The Red and Teal regions sit entirely in columns 4 and 5, so no other queen can go in those columns. The Orange and Teal regions sit entirely in rows 3 and 4, so no other queen can go in those rows. The Blue region sits entirely in row 2, so no other queen can go in row 2. Column 1 has only one open square left, so its queen goes in row 1 (Purple region) (R1C1).
5. Step 5: The Blue region has only one open square left, so its queen goes in row 2, column 3 (R2C3).
6. Step 6: The Orange region has only one open square left, so its queen goes in row 4, column 2 (R4C2).
7. Step 7: The Teal region has only one open square left, so its queen goes in row 3, column 5 (R3C5).
8. Step 8: The Red region has only one open square left, so its queen goes in row 7, column 4 (R7C4).
