Theme: Threes

Author/Opus: This is the 263rd puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Standard Cross the Streams rules. Also, the shaded region must be able to be split into tetrominoes to form a valid LITS solution (meaning all tetrominoes are connected but no two tetrominoes sharing an edge are the same shape, including rotations and reflections).

Answer String: Enter the length in cells of each of the black segments from top to bottom for the marked columns, going in order from A to B to C to D and separating each entry with a comma.

Time Standards (highlight to view): Grandmaster = 4:45, Master = 7:30, Expert = 15:00.

    Nice ending! I wonder if it would be possible to construct such a puzzle which uses the LITS restraint throughout, not only later on in the puzzle?
