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 4, so no other queen can go in column 4. The Orange and Pink regions sit entirely in rows 6 and 7, so no other queen can go in those rows. The Purple, Green and Red regions sit entirely in rows 1, 2 and 3, so no other queen can go in those rows. The Purple, Yellow and Pink regions sit entirely in columns 1, 2 and 3, so no other queen can go in those columns. The Green region sits entirely in column 5, so no other queen can go in column 5. The Orange region has only one open square left, so its queen goes in row 7, column 6 (R7C6).
2. Step 2: The Pink region has only one open square left, so its queen goes in row 6, column 2 (R6C2).
3. Step 3: Row 5 has only one open square left, so its queen goes in column 7 (Blue region) (R5C7).
4. Step 4: A queen in row 1, column 3 would leave the Red region with no open square, so that square is out. Column 3 has only one open square left, so its queen goes in row 4 (Yellow region) (R4C3).
5. Step 5: A queen in row 2, column 4 would leave the Green region with no open square, so that square is out. The Red region has only one open square left, so its queen goes in row 1, column 4 (R1C4).
6. Step 6: The Green region has only one open square left, so its queen goes in row 3, column 5 (R3C5).
7. Step 7: The Purple region has only one open square left, so its queen goes in row 2, column 1 (R2C1).
