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 Purple region sits entirely in row 1, so no other queen can go in row 1. The Gray region sits entirely in column 9, so no other queen can go in column 9. The Pink region sits entirely in row 9, so no other queen can go in row 9. The Teal region sits entirely in column 1, so no other queen can go in column 1. The Blue and Green regions sit entirely in rows 6 and 7, so no other queen can go in those rows. The Teal region has only one open square left, so its queen goes in row 8, column 1 (R8C1).
Step 2: The Purple, Orange and Blue regions sit entirely in columns 2, 3 and 4, so no other queen can go in those columns. A queen in row 2, column 8 would leave the Gray region with no open square, so that square is out. A queen in row 3, column 6 would leave column 5 with no open square, so that square is out. A queen in row 3, column 8 would leave the Gray region with no open square, so that square is out. A queen in row 4, column 6 would leave the Red region with no open square, so that square is out. A queen in row 6, column 3 would leave the Orange region with no open square, so that square is out. Row 6 has only one open square left, so its queen goes in column 7 (Green region) (R6C7).
Step 3: The Pink region has only one open square left, so its queen goes in row 9, column 8 (R9C8).
Step 4: Column 6 has only one open square left, so its queen goes in row 2 (Yellow region) (R2C6).
Step 5: The Red region has only one open square left, so its queen goes in row 5, column 5 (R5C5).
Step 6: The Gray region has only one open square left, so its queen goes in row 3, column 9 (R3C9).
Step 7: The Orange region has only one open square left, so its queen goes in row 4, column 3 (R4C3).
Step 8: The Blue region has only one open square left, so its queen goes in row 7, column 4 (R7C4).
Step 9: The Purple region has only one open square left, so its queen goes in row 1, column 2 (R1C2).
Put the queens on R1C2, R2C6, R3C9, R4C3, R5C5, R6C7, R7C4, R8C1, R9C8. That is one queen in every row, every column and every one of the 9 color regions, and no two queens touch.
