LinkedIn Queens #751 Answer & Analysis

The puzzle begins with queens already placed at R1C1 and R2C3. Once those are fixed, their rows, columns, and neighboring cells are immediately unavailable, which gives the first wave of X marks and anchors the solve.

The red region contains only one queen, and the no-touch restrictions around the given queens push it to R3C6. That placement clears the rest of the red cells, especially the ones sitting too close to the starting queens or in the same row and column lanes.

After the upper rows are constrained, the gray region in the center settles at R4C4. This is the key middle-board placement because it separates the top-half queens from the lower-half regions and removes several diagonal conflicts at once.

With the middle fixed, the green region falls into R5C7 and the yellow region into R6C5. These two placements are driven by the one-queen-per-region rule and the fact that nearby rows already have their rows, columns, and diagonals restricted.

The remaining white and blue regions complete the board at R7C2 and R8C8. Once these are placed, every row, every column, and every color region contains exactly one queen, and no queens touch.
