LinkedIn Tango #649 Answer & Analysis

First mark the given symbols and the visible edge relationships. The fixed symbols in rows 3, 5, and 6 create the strongest starting pressure, and the edge clues tell you where matching or opposite pairs must appear.

Row 3 has fixed symbols on both ends, and the Cross clue between the middle cells forces those two cells to be opposite. With the row still needing three Suns and three Moons, the entire row resolves cleanly without creating any three-in-a-row run.

The Equal clue in row 1 forces the two linked cells to match, and the row still has to end with exactly three Suns and three Moons. Once you also apply the no-three-in-a-row rule, the top row has only one clean arrangement left.

After rows 1 and 3 are fixed, the columns become much tighter. The Cross clue in row 4 forces opposite symbols in the middle, and the two given Suns on row 6 keep the last row from forming a Sun-heavy sequence in the center.

Once the other rows are fixed, the columns are close to balanced and the remaining cells are forced. The final two rows fall into place so that every column has three Suns and three Moons, and no row or column creates a three-in-a-row run.
