LinkedIn Tango #658 Answer & Analysis

Row 1 already ends with two Suns, so the two open cells beside them must be Moons to avoid three Suns in a row. In the same pass, the repeated givens at the tops of columns 1, 2, and 6 force the first few cells in row 3.

Once the outside cells are set, Row 3 has only one way to keep its 3 and 3 balance. The Equal link in the middle means the two linked cells must match, and the only balance-friendly choice is for both to be Suns, which then forces the next cell to be a Moon.

Row 4 has its own Equal link in the middle, and the columns above and below it limit the options. That makes the middle pair Moons, then the row balance and no-three rule split the ends into Moon, Sun, Moon, Moon, Sun, Sun.

With the upper rows settled, Row 5 is mostly a row-balance exercise. The existing fixed symbols and the column counts force the open cells into the alternating Sun and Moon pattern that matches the solved grid.

The remaining open cells are forced by the column totals. Row 2 must alternate correctly to stay balanced and avoid triples, and Row 6 finishes the last column counts cleanly.
