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 Red region has only one open square left, so its queen goes in row 5, column 5 (R5C5).
Step 2: The Gray region sits entirely in column 9, so no other queen can go in column 9. The Yellow region sits entirely in row 9, so no other queen can go in row 9. The Yellow and Teal regions sit entirely in columns 7 and 8, so no other queen can go in those columns. The Blue region has only one open square left, so its queen goes in row 2, column 6 (R2C6).
Step 3: The Orange region sits entirely in column 2, so no other queen can go in column 2. The Pink region sits entirely in row 8, so no other queen can go in row 8. Column 7 has only one open square left, so its queen goes in row 9 (Yellow region) (R9C7).
Step 4: The Green and Pink regions sit entirely in columns 3 and 4, so no other queen can go in those columns. Row 1 has only one open square left, so its queen goes in column 1 (Purple region) (R1C1).
Step 5: A queen in row 3, column 3 would leave the Orange region with no open square, so that square is out. A queen in row 4, column 3 would leave the Orange region with no open square, so that square is out. A queen in row 6, column 9 would leave the Teal region with no open square, so that square is out. The Gray region has only one open square left, so its queen goes in row 4, column 9 (R4C9).
Step 6: The Orange region has only one open square left, so its queen goes in row 3, column 2 (R3C2).
Step 7: A queen in row 7, column 3 would leave the Pink region with no open square, so that square is out. A queen in row 7, column 4 would leave the Pink 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 6, column 3 (R6C3).
Step 8: The Pink region has only one open square left, so its queen goes in row 8, column 4 (R8C4).
Step 9: The Teal region has only one open square left, so its queen goes in row 7, column 8 (R7C8).
Put the queens on R1C1, R2C6, R3C2, R4C9, R5C5, R6C3, R7C8, R8C4, R9C7. That is one queen in every row, every column and every one of the 9 color regions, and no two queens touch.
