LinkedIn Tango #651 Answer & Analysis

The Cross clues immediately set the cells below the top givens to the opposite symbol. That gives you a strong starting framework before any balancing work begins.

The Equal clues copy symbols between paired cells, so the lower section starts filling very quickly once one side is known.

Row 2 already has Suns at C2, C3, and C5, so C4 is forced to Moon and the remaining edge cells must be Moon to keep the row balanced. Row 3 has a Moon pattern at C2, C3, and C5, which forces the rest of the row to avoid three identical symbols in a row and to reach 3 Suns and 3 Moons.

With rows 2 and 3 set, columns 3 and 5 now force the remaining middle cells in rows 1 and 4. Row 4 then has Sun, Sun at the start, so the next cell must flip to Moon, and the row finishes with a matching Sun at the end to stay balanced.

At this point, the remaining cells are forced by column balance. Column 1, column 2, column 4, and column 6 each need the right mix of Suns and Moons, and the final row follows automatically without creating any three-in-a-row runs.
