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 and Yellow regions sit entirely in rows 2 and 3, so no other queen can go in those rows. The Red region sits entirely in row 4, so no other queen can go in row 4. The Pink region sits entirely in row 5, so no other queen can go in row 5. The Blue region sits entirely in row 6, so no other queen can go in row 6. The Yellow and Pink regions sit entirely in columns 5 and 6, so no other queen can go in those columns. The Green and Red regions sit entirely in columns 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 6, column 2 (R6C2).
2. Step 2: The Purple region has only one open square left, so its queen goes in row 1, column 1 (R1C1).
3. Step 3: The Orange region has only one open square left, so its queen goes in row 7, column 7 (R7C7).
4. Step 4: A queen in row 3, column 3 would leave the Red region with no open square, so that square is out. Row 3 has only one open square left, so its queen goes in column 6 (Yellow region) (R3C6).
5. Step 5: The Pink region has only one open square left, so its queen goes in row 5, column 5 (R5C5).
6. Step 6: The Red region has only one open square left, so its queen goes in row 4, column 3 (R4C3).
7. Step 7: The Green region has only one open square left, so its queen goes in row 2, column 4 (R2C4).
