LinkedIn Tango #615 Answer & Analysis

The Equal clue between the top two cells of column 4, followed by the Cross clue down to row 3, forces the first three cells of that column into a fixed pattern. Once the row/column balance is applied, the only fit is Sun, Sun, then Moon.

With R3C4 fixed as Moon, the Cross clue to the right forces R3C5 to be Sun. The Equal link from R3C5 to R3C6 then makes R3C6 Sun as well. That same column-6 chain also resolves the two cells above it.

The linked clues in row 4 and column 1 force a clean Sun-Moon structure. R4C1 has to match the cell below it, while the Cross clue to the right flips the next cell. That gives a strong anchor for the bottom half of the grid.

Once the left edge is settled, the balance rule and the remaining edge clues finish rows 5 and 6. The fixed Moon in row 5 and the Sun already placed in column 3 create the only pattern that avoids three identical symbols in a row.

With the middle and bottom of the board locked, the remaining open cells in rows 1 to 3 are forced by column balance. Each of the first three columns now has enough fixed symbols that the top-left block can only finish one way, and the no-three rule confirms the result.
