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 Pink region sits entirely in row 6, so no other queen can go in row 6. The Orange, Blue and Green regions sit entirely in rows 2, 3 and 4, so no other queen can go in those rows. The Yellow region sits entirely in row 5, so no other queen can go in row 5. The Red region sits entirely in row 7, so no other queen can go in row 7. Column 7 has only one open square left, so its queen goes in row 1 (Purple region) (R1C7).
2. Step 2: Column 6 has only one open square left, so its queen goes in row 3 (Blue region) (R3C6).
3. Step 3: Column 5 has only one open square left, so its queen goes in row 5 (Yellow region) (R5C5).
4. Step 4: Column 4 has only one open square left, so its queen goes in row 2 (Orange region) (R2C4).
5. Step 5: A queen in row 6, column 2 would leave the Red region with no open square, so that square is out. The Pink region has only one open square left, so its queen goes in row 6, column 1 (R6C1).
6. Step 6: The Red region has only one open square left, so its queen goes in row 7, column 3 (R7C3).
7. Step 7: The Green region has only one open square left, so its queen goes in row 4, column 2 (R4C2).
