Line Complete

This row or column already has all the ship cells its number allows — everything else in it is water.

How it works

  1. 1The top row's clue is 2, and two ship cells are already confirmed there.
  2. 2Nothing cheaper settles the rest of it: the pair's diagonals are water already, and with a 3-ship still unplaced this run isn't yet at full length.
  3. 3The clue is what stops it — the row already holds every ship cell its number allows.
  4. 4So both of the row's remaining cells are water.
