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: A queen in row 2, column 2 would leave row 1 with no open square, so that square is out. A queen in row 4, column 1 would leave the Purple region with no open square, so that square is out. The Green 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 Purple, Green, Red and Yellow regions sit entirely in columns 1, 2, 3 and 4, so no other queen can go in those columns. A queen in row 4, column 2 would leave the Green region with no open square, so that square is out. A queen in row 5, column 2 would leave the Red 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 5, column 1 (R5C1).
Step 2: The Red region has only one open square left, so its queen goes in row 6, column 3 (R6C3).
Step 3: The Yellow region sits entirely in row 8, so no other queen can go in row 8. The Purple, Gray and Beige regions sit entirely in rows 3, 4 and 7, so no other queen can go in those rows. The Orange region sits entirely in row 2, so no other queen can go in row 2. The Orange and Gray regions sit entirely in columns 7 and 8, so no other queen can go in those columns. The Beige region sits entirely in row 7, so no other queen can go in row 7. Column 7 has only one open square left, so its queen goes in row 2 (Orange region) (R2C7).
Step 4: The Blue region has only one open square left, so its queen goes in row 1, column 5 (R1C5).
Step 5: The Gray region has only one open square left, so its queen goes in row 4, column 8 (R4C8).
Step 6: The Purple region has only one open square left, so its queen goes in row 3, column 2 (R3C2).
Step 7: The Yellow region has only one open square left, so its queen goes in row 8, column 4 (R8C4).
Step 8: The Beige region has only one open square left, so its queen goes in row 7, column 6 (R7C6).
Put the queens on R1C5, R2C7, R3C2, R4C8, R5C1, R6C3, R7C6, R8C4. That is one queen in every row, every column and every one of the 8 color regions, and no two queens touch.
