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 sits entirely in row 1, so no other queen can go in row 1. The Yellow region sits entirely in row 3, so no other queen can go in row 3. The Purple region sits entirely in row 2, so no other queen can go in row 2. The Blue region sits entirely in row 4, so no other queen can go in row 4. The Purple and Red regions sit entirely in columns 1 and 2, so no other queen can go in those columns. The Green and Yellow regions sit entirely in columns 6 and 7, 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: The Yellow region has only one open square left, so its queen goes in row 3, column 7 (R3C7).
3. Step 3: The Green region has only one open square left, so its queen goes in row 1, column 6 (R1C6).
4. Step 4: A queen in row 6, column 2 would leave the Pink region with no open square, so that square is out. Column 2 has only one open square left, so its queen goes in row 2 (Purple region) (R2C2).
5. Step 5: A queen in row 6, column 3 would leave the Orange region with no open square, so that square is out. A queen in row 6, column 4 would leave the Orange 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 5, column 3 (R5C3).
6. Step 6: The Orange region has only one open square left, so its queen goes in row 7, column 4 (R7C4).
7. Step 7: The Red region has only one open square left, so its queen goes in row 6, column 1 (R6C1).
