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 Teal region has only one open square left, so its queen goes in row 1, column 1 (R1C1).
Step 2: The Purple region has only one open square left, so its queen goes in row 8, column 2 (R8C2).
Step 3: The Blue region sits entirely in column 3, so no other queen can go in column 3. The Pink region sits entirely in row 5, so no other queen can go in row 5. The Orange and Pink regions sit entirely in columns 7 and 8, so no other queen can go in those columns. A queen in row 2, column 4 would leave the Blue region with no open square, so that square is out. A queen in row 3, column 4 would leave the Blue region with no open square, so that square is out. A queen in row 3, column 5 would leave the Green region with no open square, so that square is out. A queen in row 4, column 5 would leave column 4 with no open square, so that square is out. A queen in row 2, column 6 would leave row 4 with no open square, so that square is out. A queen in row 5, column 8 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 7 (R5C7).
Step 4: The Orange region has only one open square left, so its queen goes in row 7, column 8 (R7C8).
Step 5: The Red region has only one open square left, so its queen goes in row 6, column 5 (R6C5).
Step 6: The Green region has only one open square left, so its queen goes in row 4, column 4 (R4C4).
Step 7: The Blue region has only one open square left, so its queen goes in row 2, column 3 (R2C3).
Step 8: The Yellow region has only one open square left, so its queen goes in row 3, column 6 (R3C6).
Put the queens on R1C1, R2C3, R3C6, R4C4, R5C7, R6C5, R7C8, R8C2. That is one queen in every row, every column and every one of the 8 color regions, and no two queens touch.
