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 Purple, Yellow, Red and Pink regions sit entirely in columns 1, 2, 3 and 4, so no other queen can go in those columns. The Blue region has only one open square left, so its queen goes in row 4, column 5 (R4C5).
2. Step 2: Column 4 has only one open square left, so its queen goes in row 1 (Purple region) (R1C4).
3. Step 3: The Orange region has only one open square left, so its queen goes in row 2, column 7 (R2C7).
4. Step 4: Row 3 has only one open square left, so its queen goes in column 3 (Yellow region) (R3C3).
5. Step 5: The Red region sits entirely in column 2, so no other queen can go in column 2. A queen in row 5, column 1 would leave the Red region with no open square, so that square is out. Row 5 has only one open square left, so its queen goes in column 2 (Red region) (R5C2).
6. Step 6: The Pink region has only one open square left, so its queen goes in row 7, column 1 (R7C1).
7. Step 7: The Green region has only one open square left, so its queen goes in row 6, column 6 (R6C6).
