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 Orange region has only one open square left, so its queen goes in row 1, column 2 (R1C2).
2. Step 2: The Yellow region sits entirely in column 8, so no other queen can go in column 8. The Red region sits entirely in column 5, so no other queen can go in column 5. The Green and Yellow regions sit entirely in rows 2 and 3, so no other queen can go in those rows. The Red region has only one open square left, so its queen goes in row 4, column 5 (R4C5).
3. Step 3: The Purple region has only one open square left, so its queen goes in row 5, column 1 (R5C1).
4. Step 4: Row 3 has only one open square left, so its queen goes in column 8 (Yellow region) (R3C8).
5. Step 5: The Green region has only one open square left, so its queen goes in row 2, column 6 (R2C6).
6. Step 6: The Pink region sits entirely in column 7, so no other queen can go in column 7. The Blue region has only one open square left, so its queen goes in row 6, column 4 (R6C4).
7. Step 7: The Pink region has only one open square left, so its queen goes in row 7, column 7 (R7C7).
8. Step 8: The Teal region has only one open square left, so its queen goes in row 8, column 3 (R8C3).
