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 Teal region sits entirely in column 1, so no other queen can go in column 1. The Red, Pink and Teal regions sit entirely in rows 6, 7 and 8, so no other queen can go in those rows. The Purple and Green regions sit entirely in columns 2 and 3, so no other queen can go in those columns. The Red region has only one open square left, so its queen goes in row 8, column 4 (R8C4).
2. Step 2: The Yellow region has only one open square left, so its queen goes in row 5, column 5 (R5C5).
3. Step 3: The Green region has only one open square left, so its queen goes in row 4, column 2 (R4C2).
4. Step 4: The Purple region has only one open square left, so its queen goes in row 1, column 3 (R1C3).
5. Step 5: The Orange region has only one open square left, so its queen goes in row 2, column 6 (R2C6).
6. Step 6: The Blue region has only one open square left, so its queen goes in row 3, column 8 (R3C8).
7. Step 7: The Teal region has only one open square left, so its queen goes in row 7, column 1 (R7C1).
8. Step 8: The Pink region has only one open square left, so its queen goes in row 6, column 7 (R6C7).
