LinkedIn Queens #745 Answer & Analysis

The given queens are at R1C5 and R2C7. Because each row and column must contain exactly one queen, those placements immediately remove the rest of row 1, row 2, column 5, and column 7 from consideration. Their adjacent squares are also illegal because queens cannot touch.

The green region is forced into R3C4. Once that queen is placed, row 3 and column 4 are claimed, and the neighboring cells around R3C4 are also eliminated. This is the first major non-given placement in today's Queens solution.

The yellow region fits at R4C2, and the red region lands at R5C8. These two placements work well together because they stay separated from the already-placed queens while satisfying their own region constraints.

With the center stabilized, the taupe region becomes R6C3 and the blue region becomes R7C1. These placements keep the board non-touching and preserve one queen per column.

The last queen goes in the orange region at R8C6. At this point, every row, every column, and every color region has exactly one queen, and none of the queens touch each other.
