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 Red region sits entirely in column 8, so no other queen can go in column 8. The Orange region has only one open square left, so its queen goes in row 1, column 7 (R1C7).
2. Step 2: The Yellow and Red regions sit entirely in rows 4 and 5, so no other queen can go in those rows. The Blue and Green regions sit entirely in rows 2 and 3, so no other queen can go in those rows. The Blue, Green, Yellow and Teal regions sit entirely in columns 3, 4, 5 and 6, so no other queen can go in those columns. The Purple region has only one open square left, so its queen goes in row 6, column 2 (R6C2).
3. Step 3: The Pink region has only one open square left, so its queen goes in row 8, column 1 (R8C1).
4. Step 4: Column 3 has only one open square left, so its queen goes in row 3 (Blue region) (R3C3).
5. Step 5: The Green region has only one open square left, so its queen goes in row 2, column 5 (R2C5).
6. Step 6: The Yellow region has only one open square left, so its queen goes in row 5, column 4 (R5C4).
7. Step 7: The Red region has only one open square left, so its queen goes in row 4, column 8 (R4C8).
8. Step 8: The Teal region has only one open square left, so its queen goes in row 7, column 6 (R7C6).
