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.
Step 1: The Orange region sits entirely in row 2, so no other queen can go in row 2. The Blue region sits entirely in row 3, so no other queen can go in row 3. The Green region sits entirely in row 4, so no other queen can go in row 4. The Yellow region sits entirely in row 5, so no other queen can go in row 5. The Red region sits entirely in row 6, so no other queen can go in row 6. The Pink region sits entirely in row 7, so no other queen can go in row 7. The Teal region sits entirely in row 8, so no other queen can go in row 8. Column 8 has only one open square left, so its queen goes in row 1 (Purple region) (R1C8).
Step 2: Column 7 has only one open square left, so its queen goes in row 8 (Teal region) (R8C7).
Step 3: A queen in row 2, column 5 would leave the Blue region with no open square, so that square is out. The Orange region has only one open square left, so its queen goes in row 2, column 6 (R2C6).
Step 4: The Blue region has only one open square left, so its queen goes in row 3, column 4 (R3C4).
Step 5: A queen in row 4, column 2 would leave the Yellow region with no open square, so that square is out. The Green region has only one open square left, so its queen goes in row 4, column 1 (R4C1).
Step 6: The Yellow region has only one open square left, so its queen goes in row 5, column 3 (R5C3).
Step 7: The Red region has only one open square left, so its queen goes in row 6, column 5 (R6C5).
Step 8: The Pink region has only one open square left, so its queen goes in row 7, column 2 (R7C2).
Put the queens on R1C8, R2C6, R3C4, R4C1, R5C3, R6C5, R7C2, R8C7. That is one queen in every row, every column and every one of the 8 color regions, and no two queens touch.
