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 region has only one open square left, so its queen goes in row 4, column 2 (R4C2).
2. Step 2: The Yellow region sits entirely in column 4, so no other queen can go in column 4. The Pink region sits entirely in row 7, so no other queen can go in row 7. The Red region has only one open square left, so its queen goes in row 6, column 7 (R6C7).
3. Step 3: The Yellow region has only one open square left, so its queen goes in row 5, column 4 (R5C4).
4. Step 4: The Blue region has only one open square left, so its queen goes in row 1, column 6 (R1C6).
5. Step 5: The Purple region has only one open square left, so its queen goes in row 2, column 1 (R2C1).
6. Step 6: The Orange region has only one open square left, so its queen goes in row 3, column 5 (R3C5).
7. Step 7: The Pink region has only one open square left, so its queen goes in row 7, column 3 (R7C3).
